Configure Outlook Anywhere in an Environment with Earlier Versions of Exchange
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

When you deploy the Outlook Anywhere feature (formerly known as RPC over HTTP) on a Microsoft Exchange Server 2010 Client Access server that will provide access to Microsoft Exchange Server 2007 or Exchange Server 2003, you must disable Outlook Anywhere for the earlier versions. You need to do this because Exchange 2003 and Exchange 2007 can’t provide access to a mailbox that’s hosted on an Exchange 2010 server.
After you enable Outlook Anywhere on Exchange 2010 and disable Outlook Anywhere on Exchange 2003 and Exchange 2007, you should make sure that users who have mailboxes on computers running Exchange 2003 and Exchange 2007 can access their mailboxes through Exchange 2010. To do this, create a test mailbox on each computer running Exchange 2003 and Exchange 2007. Then, perform an Outlook Anywhere (RPC over HTTP) connectivity test on each test mailbox by using Microsoft Exchange Remote Connectivity Analyzer. For more information about testing Outlook Anywhere, see Test Outlook Anywhere Connectivity.
