RPC clients such as Outlook 2003, 2007, and 2010 use CAS servers as their MAPI endpoint for mailbox access in Exchange 2010. In this recipe, you will learn how to control which CAS server or CAS array will be used as the MAPI endpoint by configuring the properties of the user's mailbox database using the Exchange Management Shell.
To configure the CAS server that should be used by RPC clients, set the RPCClientAccessServer
property of the user's mailbox database. For example:
Set-MailboxDatabase -Identity DB1 ` -RpcClientAccessServer outlook.contoso.com
After running the previous command, any user with a mailbox in the DB1
database will use outlook.contoso.com
for RPC connections.
