Configure the Autodiscover Service for Multiple Forests
Applies to: Exchange Server 2010
You can use the Shell to configure the Autodiscover service when your Microsoft Exchange deployment has two or more trusted forests.
To configure the Autodiscover service when your deployment has two or more trusted forests, you must update Active Directory so that users who are running Microsoft Office Outlook 2007 or Outlook 2010 in one forest can access the Client Access servers in the remote (or target) forest to use the Autodiscover service. To do this, you run the Export-AutodiscoverConfig cmdlet in each forest that contains the Client Access servers that provide the Autodiscover service against the target forests. This configures the service connection point (SCP) information for the Autodiscover pointer in Active Directory.
