Enable-OutlookAnywhere

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:

  • Basic (Basic authentication)
  • Digest (Digest authentication)
  • Ntlm (NTLM authentication)
  • Fba (forms-based authentication)
  • WindowsIntegrated (Integrated Windows authentication)
  • LiveIdFba (Windows Live ID forms-based authentication)
  • LiveIdBasic (Windows Live ID Basic authentication)
  • WSSecurity (Windows SharePoint Security)
  • Certificate
  • NegoEx
  • MaxValidValue
  • Misconfigured
Bb124993.note(en-us,EXCHG.140).gifNote:
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:

  • Basic (Basic authentication)
  • Ntlm (NTLM authentication)
  • Digest (Digest authentication)
  • Fba (forms-based authentication)
  • WindowsIntegrated (Integrated Windows authentication)
  • LiveIdFba (Windows Live ID forms-based authentication)
  • LiveIdBasic (Windows Live ID Basic authentication)
  • WSSecurity (Windows SharePoint Security)
  • Certificate
  • NegoEx
  • MaxValidValue
  • Misconfigured
Bb124993.note(en-us,EXCHG.140).gifNote:
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 $true when an SSL hardware solution is running in front of the Client Access server.

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.

Bb124993.important(en-us,EXCHG.140).gifImportant:
This cmdlet can be successfully run only if the RPC over HTTP proxy Windows networking component is already installed.
Bb124993.note(en-us,EXCHG.140).gifNote:
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.

Exceptions Description

 

 

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.
