Set-MapiVirtualDirectory

 

Applies to: Exchange Server 2016

Topic Last Modified: 2017-01-23

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Set-MapiVirtualDirectory cmdlet to modify Messaging Application Programming Interface (MAPI) virtual directories that are used in Internet Information Services (IIS) on Microsoft Exchange servers. A MAPI virtual directory is used by supported versions of Microsoft Outlook to connect to mailboxes by using the MAPIHTTP protocol.

Set-MapiVirtualDirectory -Identity <VirtualDirectoryIdParameter> [-ApplyDefaults <$true | $false>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-ExternalUrl <Uri>] [-IISAuthenticationMethods <MultiValuedProperty>] [-InternalUrl <Uri>] [-WhatIf [<SwitchParameter>]]

This example makes the following configuration changes to the MAPI virtual directory on the default web site of the server named ContosoMail:

  • Internal URL   https://contoso/mapi.

  • IIS authentication methods   NTLM, Negotiate, and OAuth.

Set-MapiVirtualDirectory -Identity "ContosoMail\mapi (Default Web Site)" -InternalUrl https://contoso.com/mapi -IISAuthenticationMethods NTLM,Negotiate,OAuth

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Client Access virtual directory settings" entry in the Clients and mobile devices permissions topic.

 

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Configuration.Tasks.VirtualDirectoryIdParameter

The Identity parameter specifies the MAPI virtual directory that you want to configure.

You can use any value that uniquely identifies the virtual directory. For example:

  • Name or <Server>\Name

  • Distinguished name (DN)

  • GUID

The Name value uses the syntax "<VirtualDirectoryName> (<WebsiteName>)" from the properties of the virtual directory. You can specify the wildcard character (*) instead of the default website by using the syntax <VirtualDirectoryName>*.

ApplyDefaults

Optional

System.Boolean

The ApplyDefaults switch specifies whether to apply the correct defaults to the related internal IIS application settings. Typically, this switch is used only by Exchange setup during the installation of Exchange Cumulative Updates or Service Packs, and you shouldn't need to use it.

This switch doesn't affect the values you configure by using the IISAuthenticationMethods, InternalUrl or ExternalUrl parameters.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

ExternalUrl

Optional

System.Uri

The ExternalURL parameter specifies the URL that's used to connect to the virtual directory from outside the firewall.

This setting enforces the Secure Sockets Layer (SSL) protocol and uses the default SSL port. Valid input for this parameter uses the syntax https://<Domain Name>/mapi.

When you use the InternalUrl or ExternalUrl parameters, you need to specify one or more authentication values by using the IISAuthenticationMethods parameter.

IISAuthenticationMethods

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The IISAuthenticationMethods parameter specifies the authentication methods that are enabled on the virtual directory in Internet Information Services (IIS). Valid values are:

  • Basic

  • Negotiate

  • NTLM

  • OAuth

You can specify multiple values separated by commas.

The default values are NTLM, OAuth, and Negotiate. We recommend that you always have the virtual directory configured for OAuth.

InternalUrl

Optional

System.Uri

The InternalURL parameter specifies the URL that's used to connect to the virtual directory from inside the firewall.

This setting enforces the Secure Sockets Layer (SSL) protocol and uses the default SSL port. Valid input for this parameter uses the syntax https://<Domain Name>/mapi.

When you use the InternalUrl or ExternalUrl parameters, you need to specify one or more authentication values by using the IISAuthenticationMethods parameter.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
