Applies to: Exchange Server 2010
Topic Last Modified: 2011-03-19
Use the Enable-OutlookAnywhere cmdlet to enable Outlook Anywhere on a computer running Microsoft Exchange Server 2010 that has the Client Access server role installed. Running the Enable-OutlookAnywhere cmdlet enables the server to accept requests from Microsoft Office Outlook 2007 and Outlook 2003 client computers from the Internet by using Outlook Anywhere, also known as RPC over HTTP.

| Parameter | Required | Type | Description |
|---|---|---|---|
|
ClientAuthenticationMethod |
Required |
Microsoft.Exchange.Data.Directory.SystemConfiguration.AuthenticationMethod |
The ClientAuthenticationMethod parameter specifies the authentication method that the Autodiscover service provides to the Outlook Anywhere clients to authenticate to the Client Access server. The authentication method can be set to one of the following:
 Note:
This parameter must be specified if you don't use the DefaultAuthenticationMethod parameter. When you use this parameter without specifying the IISAuthenticationMethods parameter, IISAuthenticationMethods parameter is set to both NTLM and Basic.
|
|
DefaultAuthenticationMethod |
Required |
Microsoft.Exchange.Data.Directory.SystemConfiguration.AuthenticationMethod |
The DefaultAuthenticationMethod parameter specifies whether to set both the ClientAuthenticationMethod and IISAuthenticationMethods parameters to the same authentication value. When you set an authentication value by using the DefaultAuthenticationMethod parameter, you force the specified authentication method to be used on the /rpc virtual directory in Internet Information Services (IIS). The authentication method can be set to one of the following:
Note:
If the DefaultAuthenticationMethod parameter is specified, neither the ClientAuthenticationMethod nor the IISAuthenticationMethods parameter can be used.
|
|
ExternalHostname |
Required |
Microsoft.Exchange.Data.Hostname |
The ExternalHostname parameter specifies the external host name to use in the Outlook profiles for users enabled for Outlook Anywhere. |
|
SSLOffloading |
Required |
System.Boolean |
The SSLOffloading parameter specifies whether the Client Access server requires Secure Sockets Layer (SSL). This value should be set only to |
|
Confirm |
Optional |
System.Management.Automation.SwitchParameter |
The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch. |
|
DomainController |
Optional |
Microsoft.Exchange.Data.Fqdn |
The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory. |
|
IISAuthenticationMethods |
Optional |
Microsoft.Exchange.Data.MultiValuedProperty |
The IISAuthenticationMethods parameter specifies the authentication method that's enabled on the /rpc virtual directory in IIS. All other authentication methods are disabled. This authentication method can be set to Basic or NTLM. |
|
Server |
Optional |
Microsoft.Exchange.Configuration.Tasks.ServerIdParameter |
The Server parameter specifies the name of the Client Access server to be enabled for Outlook Anywhere. |
|
WhatIf |
Optional |
System.Management.Automation.SwitchParameter |
The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch. |
The Enable-OutlookAnywhere cmdlet enables the Exchange 2010 Client Access server for Outlook Anywhere. This lets the server accept requests from Outlook 2007 and Outlook 2003 clients from the Internet by using Outlook Anywhere.
| Important: |
|---|
| This cmdlet can be successfully run only if the RPC over HTTP proxy Windows networking component is already installed. |
| Note: |
|---|
| When you run this cmdlet, it can take as long as an hour for the settings to become effective, depending on how long it takes for Active Directory to replicate. |
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 "Outlook Anywhere configuration settings" entry in the Client Access Permissions topic.

This example enables the server Server01 for Outlook Anywhere. The external host name is set to mail.contoso.com, both Basic and NTLM authentication are used, and SSL offloading is set to $true.
Enable-OutlookAnywhere -Server:Server01 -ExternalHostname:mail.contoso.com -ClientAuthenticationMethod:Ntlm -SSLOffloading:$true
This example enables Outlook Anywhere on the server that has the Client Access role installed. The SSLOffloading parameter is set to $false, the ExternalHostname parameter is specified as mail.contoso.com, and the DefaultAuthenticationMethod parameter is set to NTLM.
Enable-OutlookAnywhere -DefaultAuthenticationMethod:Ntlm -ExternalHostname:mail.contoso.com -SSLOffloading:$false
This example enables the Exchange Client Access server for Outlook Anywhere. The SSLOffloading parameter is set to $false, the ExternalHostname parameter is set to mail.contoso.com, the IISAuthenticationMethods parameter is set to NTLM, and the ClientAuthenticationMethod parameter is set to Basic.
Enable-Outlookanywhere -IISAuthenticationMethods NTLM -SSlOffloading:$false -ClientAuthenticationMethod:Basic -ExternalHostname:mail.contoso.com
