We have been running an Exchange mail server, and just switched to using Google Apps Premier. Everything is generally working fine, and MX records now point to Google, so all mail is routed there.
The Exchange server is therefore no longer needed. However, we have a few legacy processes that still send mail through the Exchange server, and those won't be updated right away. Any e-mail sent to external addresses from the old Exchange server work fine. But and messages sent to users within the domain stay within Exchange, and never hit the new Google Apps mailboxes.
How can I change this so those messages sent within the domain look at the MX record and route appropriately? I think I have to change something within the Recipient Policies in Exchange System Manager, but I don't know what.
Thanks for any help.
