Configure incoming email for a SharePoint Server farm

APPLIES TO: yes-img-132013 yes-img-162016 yes-img-192019 yes-img-seSubscription Edition no-img-sopSharePoint in Microsoft 365

This article describes how to configure incoming email for SharePoint Server. This article also describes how to install and configure the SharePoint Migration Tool service to enable incoming email.

When incoming email is enabled, SharePoint sites can receive and store email messages and attachments in lists and libraries. This article describes two scenarios, one basic and one advanced. The basic scenario applies to a single-server farm environment and is recommended if you want to use default settings. The advanced scenario applies to a single-server farm or a multiple-server farm and contains several advanced options from which to choose. For more information, see Plan incoming email for a SharePoint Server farm.

Before you begin

Before you begin this operation, make sure to review the following information:

  • Your system is running SharePoint Server 2016, SharePoint Server 2019, or SharePoint Server Subscription Edition.

  • Read and understand Plan incoming email for a SharePoint Server farm.

  • For the basic scenario, each SharePoint application server must be running the Simple Mail Transfer Protocol (SMTP) service and the SharePoint Foundation Web Application service.

Note

The basic scenario is not available for SharePoint Server 2019 or SharePoint Server Subscription Edition.

  • For the advanced scenario, you can use one or more servers in the server farm to run the SMTP service and to have a valid SMTP server address. Alternatively, you must know the name of a server outside the farm that is running the SMTP service and the location of the email drop folder.

If you have not installed and configured the SMTP service and do not choose to use an email drop folder, you must complete the steps in Install and configure the SMTP service before you configure incoming email.

Install and configure the SMTP service

Incoming email for SharePoint Server uses the SMTP service. You can use the SMTP service in one of two ways. You can install the SMTP service on one or more servers in the farm, or administrators can provide an email drop folder for email that is forwarded from the service on another server. For more information about the email drop folder option, see Plan incoming email for a SharePoint Server farm.

Note

The IIS 6 management features used by the IIS SMTP service have been deprecated. Administrators should instead use “Advanced Mode” and configure an e-mail drop folder, as detailed in Does SharePoint 2019 still need the SMTP Service.

Install the SMTP service

If you are not using a drop folder for email, the SMTP service must be installed on every application server in the farm that you want to configure for incoming email. To install the SMTP service, use the Add Roles and Features Wizard in Server Manager. After you complete the procedure, the SMTP service is installed on the application server.

To install the SMTP service

  1. Verify that the user account that is performing this procedure is a member of the Administrators group on the application server.

  2. Open Server Manager, select Manage, and then select Add Roles and Features.

  3. Select Next until the Select features page appears, select SMTP Server, select Add Features, and then select Next.

  4. On the Confirm Installation Selections page, select Install.

  5. On the Installation Results page, check that the installation finished successfully, and then select Close.

Install IIS 6.0 Management tools

To manage the SMTP service on Windows Server 2012 R2, Windows Server 2016, Windows Server 2008, and Windows Server 2008 R2 you must use Internet Information Services (IIS) 6.0 Manager. However, if you install the SMTP service on Windows Server 2016, the Add Roles and Features Wizard automatically installs the IIS 6 Management tools.

To install IIS 6.0 Manager

  1. Verify that you have the following administrative credentials:
  • You must be a member of the Administrators group on the front-end web server.
  1. Open Server Manager, select Manage, and then select Add Roles and Features.

  2. Select Next until the Select server roles page appears, select Management Tools and IIS 6 Management compatibility, and then select Install.

  3. In Application Server section, select Add Role Services.

  4. On the Select Role Services page, select Management Tools and IIS 6 Management compatibility, and then select Install.

Configure the SMTP service

After you install the SMTP service, you configure it to accept email from the mail server for the domain. You can decide to accept relayed email from all servers except those that you specifically exclude. Alternatively, you can block email from all servers except those that you specifically include. You can include servers individually, in groups by subnet, or in groups by domain.

After you configure the service, set it to start automatically.

To configure the SMTP service

  1. Verify that the user account that is performing this procedure is a member of the Administrators group on the application server.

  2. Open Server Manager, select Tools, and then select Internet Information Services (IIS) 6.0 Manager.

  3. In IIS Manager, expand the server name that contains the SMTP server that you want to configure.

  4. Right-click the SMTP virtual server that you want to configure, select Start, and then right-click the server again, and select Properties.

  5. On the Access tab, in the Access control area, select Authentication.

  6. In the Authentication dialog, verify that Anonymous access is selected, and select OK.

  7. On the Access tab, in the Relay restrictions area, select Relay.

  8. To enable relaying from any server, select All except the list below.

  9. To accept relaying from one or more specific servers, follow these steps:

  • Select Only the list below.

  • Select Add, and then add servers one at a time by IP address, or in groups by using a subnet or domain.

  • Select OK three times to close the Computer, Relay Restrictions, and Properties dialogs.

To set the SMTP service to start automatically

  1. Open Server Manager, select Tools, and then select Services.

  2. In Services, right-click Simple Mail Transfer Protocol (SMTP), and then select Properties.

  3. In the Simple Mail Transfer Protocol (SMTP) Properties dialog, on the General tab, in the Startup type list, select Automatic, and select OK.

Configure incoming email in a basic scenario

You can use the following procedure to configure incoming email in a basic scenario by selecting the Automatic settings mode and using the default settings. After you complete the procedure, users can send email to lists and libraries.

Note

Automatic mode is not available in SharePoint Server 2019 or SharePoint Server Subscription Edition.

To configure incoming email in a basic scenario

  1. Make sure the user account that is performing this procedure is a member of the Administrators group on the server that is running the SharePoint Central Administration website.

  2. In Central Administration, select System Settings, and in the E-Mail and Text Messages (SMS) section, select Configure incoming e-mail settings.

  3. To enable sites on this server to receive email, on the Configure Incoming E-Mail Settings page, in the Enable Incoming E-Mail section, select Yes.

  4. Select the Automatic settings mode.

  5. In the Incoming E-Mail Server Display Address section, in the E-mail server display address box, enter a display name for the email server, for example, mail.fabrikam.com.

  6. Use the default settings for all other sections, and then select OK.

After you configure incoming email, users who have Manage Lists permissions can configure email-enabled lists and document libraries.

Configure incoming email in an advanced scenario

The following procedure explains how to configure incoming email in an advanced scenario by selecting the Advanced settings mode and additional options that you want to use for your incoming email environment. After you complete the procedure, users can send email to lists and libraries.

You can also use the Automatic settings mode in an advanced scenario. In the Automatic settings mode, you can select to receive email that has been routed through a safe-email server application. In the Advanced settings mode, you can instead specify a drop folder. For more information, see Plan incoming email for a SharePoint Server farm.

Several of these steps mention prerequisite procedures that are documented in Prepare your environment for incoming email in an advanced scenario later in this article.

To configure incoming email in an advanced scenario

  1. Make sure the user account that is performing this procedure is a member of the Administrators group on the server that is running the SharePoint Central Administration website.

  2. In the Central Administration website, select System Settings, in the E-Mail and Text Messages (SMS) section, select Configure incoming e-mail settings.

  3. To enable sites on this server to receive email, on the Configure Incoming E-mail Settings page, in the Enable Incoming E-Mail section, select Yes.

  4. Select the Advanced settings mode.

    You can specify a drop folder instead of using an SMTP server. The default location of the drop folder is C:\inetpub\mailroot\drop. You can configure a different location if you want but this drop folder must be the same on all SharePoint Servers.

    Note

    You can also select the Automatic settings mode and select whether to use Directory Management Service and whether to accept email from all email servers or from several specified email servers. For more information, see Plan incoming email for a SharePoint Server farm.

  5. If you want to connect to Directory Management Service, in the Directory Management Service section, select Yes.

    If you select this option, you must first configure Active Directory Domain Services (AD DS). If you use Exchange Server, you must also configure the DNS Manager and add an SMTP connector. For more info, see Configure AD DS to be used with Directory Management Service, Configure DNS Manager, and Add an SMTP connector in Microsoft Exchange Server 2016 later in this article.

  • In the Active Directory container where new distribution groups and contacts will be created box, enter the name of the container in the format OU= ContainerName , DC= domain , DC= com, where ContainerName is the name of the OU in AD DS, domain is the second-level domain, and com is the top-level domain.

    The application pool identity account for Central Administration must be delegated the Create, delete, and manage user accounts task for the container. Access is configured in the properties for the OU in AD DS.

  • In the SMTP mail server for incoming mail box, enter the name of the SMTP mail server. The server name must match the FQDN in the A resource record entry for the mail server in DNS Manager.

  • To accept messages only from authenticated users, for Accept messages from authenticated users only, select Yes; otherwise, select No.

  • To enable users to create distribution groups from SharePoint sites, for Allow creation of distribution groups from SharePoint sites, select Yes; otherwise, select No.

  • Under Distribution group request approval settings, select the actions that will require approval. Actions include the following:

  • Create new distribution group

  • Change distribution group e-mail address

  • Change distribution group title and description

  • Delete distribution group

  1. If you want to use a remote Directory Management Service, select Use remote and complete the remainder of this step. Otherwise, select No, and proceed to step 8.

    If you select this option and you are using Exchange Server, you must configure the DNS Manager and add an SMTP connector. For more info, see Configure DNS Manager, Add an SMTP connector in Microsoft Exchange Server 2016 later in this article. The AD DS has most likely already been configured, so you do not need to do this.

  • In the Directory Management Service URL box, enter the URL of the Directory Management Service that you want to use. The URL is typically in the following format: http:// server:adminport/_vti_bin/SharePointEmailWS.asmx.

  • In the SMTP mail server for incoming mail box, enter the name of the SMTP mail server. The server name must match the FQDN in the A resource record entry for the mail server in DNS Manager on the domain server.

  • To accept messages from authenticated users only, for Accept messages from authenticated users only, select Yes; otherwise, select No.

  • To allow creation of distribution groups from SharePoint sites, for Allow creation of distribution groups from SharePoint sites, select Yes; otherwise, select No.

  1. In the Incoming E-Mail Server Display Address section, in the E-mail server display address box, enter a display name for the email server (for example, mail.fabrikam.com). You typically use this option together with the Directory Management Service.

    Tip

    You can specify the email server address that is displayed when users create an incoming email address for a list or group. Use this setting together with Directory Management Service to provide an email server address that is easy to remember.

  2. In the E-Mail Drop Folder section, in the E-mail drop folder box, type the name of the folder from which the Windows SharePoint Services Timer service retrieves incoming email from the SMTP service. This option is available only if you selected Advanced settings mode. If you select this option, ensure that you configure the necessary permissions to the email drop folder. For more information, see Configure permissions to the email drop folder later in this article.

    It is useful to have a dedicated email drop folder if the default email drop folder is full or almost full. The default location of the drop folder is C:\inetpub\mailroot\drop. You can configure a different location if you want but this drop folder must be the same on all SharePoint Servers.

    Ensure that the logon account for the SharePoint Timer service has Modify permissions on the email drop folder.

  3. In the Safe E-Mail Servers section, select whether you want to accept email from all email servers or from specific email servers.

    This option is available only if you selected Automatic settings mode.

  4. Select OK.

After you configure incoming email, site administrators can configure email-enabled lists and document libraries.

If you selected Directory Management Service, contact addresses that are created for document libraries appear automatically in Active Directory Users and Computers. The addresses are displayed in the OU of AD DS for SharePoint Server and must be managed by the administrator of AD DS. The AD DS administrator can add more email addresses for each contact. For more information about AD DS, see AD DS Getting Started.

Alternatively, you can configure the computer running Exchange Server by adding a new Exchange Server Global recipient policy. The policy automatically adds external addresses that use the second-level domain name and not the subdomain or host name for SharePoint Server.

Prepare your environment for incoming email in an advanced scenario

Before you configure incoming email in an advanced scenario, you need to perform additional procedures depending on how you want your incoming email environment to work.

If you want to use Directory Management Service, you must first configure AD DS, and if you use Exchange Server, you must also configure the DNS Manager and add an SMTP connector.

If you want to use a specific email drop folder, ensure that you configure the necessary permissions to the email drop folder.

In this section:

Configure AD DS to be used with Directory Management Service

If you plan to use Directory Management Service, you should first create an organizational unit (OU) and make the necessary configurations in AD DS.

To use Directory Management Service on a SharePoint farm, you must configure the application pool identity account for the SharePoint Central Administration website to have the Create, delete, and manage user accounts user right to the container that you specify in AD DS. The preferred way to do this is to assign the right to the application pool identity account for the SharePoint Central Administration website. An AD DS administrator must set up the OU and assign the Create, delete, and manage user accounts right to the container. The advantage of using Directory Management Service on a remote server farm is that you do not have to assign rights to the OU for multiple farm service accounts.

The following procedures are performed on a domain controller that runs Windows Server 2008 and Windows Server 2012 R2 with DNS Manager. In some deployments, these applications might run on multiple servers in the same domain.

To create an OU in AD DS

  1. Make sure the user account that is performing this procedure is a member of the Domain Administrators group or a delegated authority for domain administration on the domain controller that is running DNS Manager.

  2. Open Server Manager, select Tools, and then select Active Directory Users and Computers.

  3. In Active Directory Users and Computers, right-click the folder for the second-level domain that contains your server farm, point to New, and then select Organizational Unit.

  4. Enter the name of the OU, and then select OK.

    After you create the OU, you must delegate the Create, delete, and manage user accounts right to the container of the OU to manage the user accounts.

To delegate the right to the application pool identity account for Central Administration

  1. Make sure the user account that is performing this procedure is a member of the Domain Administrators group or the Enterprise Administrators group in AD DS, or a delegated authority for domain administration.

  2. In Active Directory Users and Computers, right-click the OU that you created, and then select Delegate control.

  3. On the Welcome page of the Delegation of Control Wizard, select Next.

  4. On the Users and Groups page, select Add, and then enter the name of the application pool identity account that the Central Administration uses.

  5. In the Select Users, Computers, and Groups dialog, select OK.

  6. On the Users or Groups page of the Delegation of Control Wizard, select Next.

  7. On the Tasks to Delegate page of the Delegation of Control Wizard, select the Create, delete, and manage user accounts check box, and then select Next.

  8. On the last page of the Delegation of Control Wizard, to exit the wizard, select Finish.

To create and delete child objects, you must also delegate Create all Child Objects and Delete all Child Objects control of the OU to the application pool identity account for Central Administration. After you complete this procedure, the application pool identity account for Central Administration has Create all Child Objects and Delete all Child Objects control on the OU, and you can enable incoming email.

To delegate Create all Child Objects and Delete all Child Objects control of the OU to the application pool identity account for Central Administration

  1. Make sure the user account that is performing this procedure is a member of the Domain Administrators group or the Enterprise Administrators group in AD DS, or a delegated authority for domain administration.

  2. Right-click the OU, and then select Delegate control.

  3. In the Delegation of Control Wizard, select Next.

  4. Select Add, and then enter the name of the application pool identity account for Central Administration, select OK, and then select Next.

  5. On the Tasks to Delegate page of the Delegation of Control Wizard, select Create a custom task to delegate, and then select Next.

  6. Select This folder, existing objects in this folder, and creation of new objects in this folder, and then select Next.

  7. In the Permissions section, select Create all Child Objects and Delete all Child Objects, and then select Next.

  8. On the last page of the Delegation of Control Wizard, to exit the wizard, select Finish.

Delegating Create all Child Objects and Delete all Child Objects control of the OU to the application pool identity account for Central Administration enables administrators to enable email for a list. After these controls have been delegated, administrators cannot disable email for the list or document library because the Central Administration account tries to delete the contact from the whole OU instead of from the list. To avoid this problem, you must add Delete Subtree permissions for the application pool identity account for Central Administration. Use the following procedure to add these permissions. After this procedure is complete, you can disable incoming email for a list.

To add Delete Subtree permissions for the application pool identity account for Central Administration

  1. Make sure the user account that is performing this procedure is a member of the Domain Administrators group or the Enterprise Administrators group in AD DS, or a delegated authority for domain administration.

  2. In Active Directory Users and Computers, select the View menu, and then select Advanced Features.

  3. Right-click the OU, and then select Properties.

  4. In the Properties dialog, select the Security tab, and then select Advanced.

  5. In the Permission Entries area, double-click the application pool identity account for Central Administration.

    If the application pool identity account is listed more than once, select the first one.

  6. In the Permissions area, for Delete Subtree, select Allow.

  7. Select OK three times to close the Permissions, Properties dialogs, and Active Directory Users and Computers.

After you add these permissions, you must restart IIS for the farm.

Configure DNS Manager

If you are using Exchange Server and are routing email internally in your organization, you must create a host (A) resource record in DNS Manager to associate DNS domain names of computers (or hosts) to their IP addresses. Your organization might already have a configured DNS Manager and an A resource record. If not, then use the following procedure.

To create an A resource record for a subdomain

  1. Make sure the user account that is performing this procedure is a member of the Administrators group on the local computer.

  2. In DNS Manager, select the forward lookup zone for the domain that contains the subdomain for SharePoint Server.

  3. Right-click the zone, and then select New Host (A or AAAA).

  4. In the New Host dialog, in the Name text box, enter the host or subdomain name for SharePoint Server.

  5. In the Fully qualified domain name (FQDN) text box, enter the FQDN for the server that is running SharePoint Server. This is typically in the format subdomain.domain.com.

  6. Ensure that the domains that are listed under the SMTP server in IIS match the FQDN of the server that receives email. If they do not match, you must create a local domain. For instructions, see To create a local domain later in this article.

  7. In the IP address text box, enter the IP address to which you want the FQDN to resolve.

  8. Select Add Host.

  9. In the message that confirms the creation of the host record, select OK, and in the New Host dialog, select Done.

    The A resource record now appears in DNS Manager.

If you use the E-mail server display address option and if the email address to which you are sending email messages is not the same as your server name, you must create a local domain.

To create a local domain

  1. Open Server Manager, select Tools, and then select Internet Information Services (IIS) 6.0 Manager.

  2. In IIS Manager, expand the SMTP server, right-click Domains, and on the Action menu, point to New, and then select Domain.

  3. In the New SMTP Domain Wizard dialog, select Alias, and then select Next.

  4. In the Domain Name area, in the Name box, enter the address of the mail that is to be received by this domain.

    This address must be the same as the one that you specified in step 4 in To create an A resource record for a subdomain, and in step 6b in To configure incoming email in an advanced scenario.

  5. Select Finish.

  6. In the message that confirms the creation of the host record, select OK.

  7. Restart the SMTP server so that all email messages that are still in the Queue folder move to the Drop folder. The messages are then sent by the Windows SharePoint Services Timer service to their destination list or library.

Note

If you are routing email from outside your organization to an SMTP server, you must use an MX record. For more information, see Add a mail exchanger (MX) resource record to a zone.

Add an SMTP connector in Microsoft Exchange Server 2016

An SMTP connector gives you more control over the message flow in your organization. Other reasons to use an SMTP connector are to set delivery restrictions or to specify a specific address space. If you use Exchange Server to route incoming email to SharePoint lists and libraries, you must have an SMTP connector so that all mail that is sent to the SharePoint domain uses the servers that are running the SMTP service.

Use the following procedure to add an SMTP connector in Exchange Server. After you complete the procedure, the SMTP connector ensures that incoming email messages are sent to the correct list and library in the farm.

Important

A “Send Connector” should only be selected if you are using a local IIS SMTP service on the SharePoint servers, which has been deprecated in Windows Server.
If you are using an e-mail drop folder, which is required for SharePoint Server 2019 and SharePoint Server Subscription Edition, a Foreign Connector must be used, as outlined in Does SharePoint 2019 still need the SMTP Service.

To add an SMTP connector in Exchange Server

  1. Verify that the user account that is performing this procedure is a member of the Administrators group on the server that is running Exchange Server.

  2. In Exchange Admin Center, select mail flow, highlight send connectors, and to open the new send connector wizard, select the + (Add) icon.

  3. On the Introduction page, do the following, and then select Next.

  4. In the Name box, enter a name for the SMTP connector.

  5. In the Select the intended use for this Send connector box, select the Custom usage type for the connector.

  6. On the Network settings page, select MX record associated with recipient domain, and then select Next.

  7. On the Address Space page, select the + (Add) icon, and in the Address Space webpage dialog, do the following:

  • In the Full Qualified Domain Name (FQDN) box, enter an email domain for the connector. This is the FQDN for the SharePoint Server that runs the SMTP service.

  • In the Cost box, assign an appropriate cost. By default, the cost is 1.

  1. To return to the Address Space page, select Save, and then select Next.

  2. On the Source Server page, select the + (Add) icon. The Select a Server page appears.

  3. Select add, and then select OK.

  4. On the new send connector wizard, select Finish.

    The Source server page requires a server that contains transport roles.

For more info, see Learn more about Send connector types in the Exchange Server Technical Library.

Configure permissions to the email drop folder

You can specify a particular email drop folder, which enables SharePoint Server to retrieve incoming email from a network share on another server. You can use this option if you do not want to use an SMTP service. However, the drawback of using this option is that SharePoint Server cannot detect configuration changes on the remote email server that is delivering email to the drop folder. The result is that SharePoint Server cannot retrieve email if the location of the email messages has changed. However, this feature is useful if the default email drop folder is full or almost full.

If you specified an email drop folder, you must ensure that the application pool identity accounts for Central Administration and for the web application have the required permissions to the email drop folder.

Configure email drop folder permissions for the application pool identity account for a web application

If your deployment uses different application pool identity accounts for Central Administration and for one or more web applications, each application pool identity account must have permissions to the email drop folder. If the application pool identity account for the web application does not have the required permissions, email will not be delivered to document libraries on that web application.

In most cases, when you configure incoming email and select an email drop folder, permissions are added for the following worker process groups:

  • WSS_Admin_WPG, which includes the application pool identity account for Central Administration and the logon account for the SharePoint Timer service, and has Full Control permissions.

  • WSS_WPG, which includes the application pool accounts for web applications, and has Read & Execute, List Folder Contents, and Read permissions.

In some cases, these groups might not be configured automatically for the email drop folder. For example, if Central Administration is running as the Network Service account, the groups or accounts that are needed for incoming email will not be added when the email drop folder is created. Check to determine whether these groups have been added automatically to the email drop folder. If the groups have not been added automatically, you can add them or add the specific accounts that are required.

To configure email drop folder permissions for the application pool identity account for a web application

  1. Verify that the user account that is performing this procedure is a member of the Administrators group on the server that contains the email drop folder.

  2. In File Explorer, right-click the drop folder, select Properties, and then select the Security tab.

  3. On the Security tab, under the Group or user names box, select Edit.

  4. In the Permissions for Drop dialog, select Add.

  5. In the Select Users, Computers, Service Accounts, or Groups dialog, in the Enter the object names to select box, enter the name of the worker process group or application pool identity account for the web application, and then select OK.

    This account is listed on the Identity tab of the Properties dialog for the application pool in IIS.

  6. In the Permissions for User or Group box, next to Modify, select Allow.

  7. Select OK.

Configure email drop folder permissions for the logon account for the SharePoint Timer service

Ensure that the logon account for the Windows SharePoint Services Timer service has Modify permissions on the email drop folder. If the logon account for the service does not have Modify permissions, email-enabled document libraries will receive duplicate email messages.

To configure email drop folder permissions for the logon account for the SharePoint Timer service

  1. Verify that the user account that is performing this procedure is a member of the Administrators group on the server that contains the email drop folder.

  2. In File Explorer, right-click the drop folder, select Properties, and then select the Security tab.

  3. On the Security tab, under the Group or user names box, select Edit.

  4. In the Permissions for Drop dialog, select Add.

  5. In the Select Users, Computers, Service Accounts, or Groups dialog, in the Enter the object names to select box, enter the name of the logon account for the SharePoint Timer service, and then select OK.

    This account is listed on the Log On tab of the Properties dialog for the service in the Services snap-in.

  6. In the Permissions for User or Group box, next to Modify, select Allow.

  7. Select OK.

Are attachments missing from email messages that are sent to a SharePoint document library?

If attachments are missing from email messages that are sent to a SharePoint document library, it might be because you associated the document library with an email address. When you do this, Directory Management Service may not add the following two attributes to the user associated with the email address:

  • internet Encoding = 1310720

  • mAPIRecipient = false

You must use Active Directory Service Interfaces (ADSI) to manually add these two missing attributes.

On servers that are running Windows Server 2012 R2, Windows Server 2016, Windows Server 2008, or Windows Server 2008 R2, ADSI Edit is installed when you configure a server as a domain controller by installing the AD DS role.

To add attributes by using ADSI Edit

  1. Select Start, and then select Run.

  2. In the Run dialog, enter Adsiedit.msc, and then select OK.

  3. In the ADSI Edit window, expand ADSI Edit, expand Domain [DomainName], expand DC=DomainName, DC=com, and then expand CN=Users.

  4. Right-click the user name to which you want to add the missing attributes, and then select Properties.

  5. In the Properties dialog, on the Attribute Editor tab, double-click Internet Encoding.

  6. In the Integer Attribute Editor dialog, enter 1310720 in the Value box, and then select OK.

  7. In the Properties dialog, on the Attribute Editor tab, double-click mAPIRecipient.

  8. In the Boolean Attribute Editor dialog, select False, and then select OK two times.
