I have three Exchange 2003 Exchange servers. I moved all the mailboxes off the oldest server and was going to keep it around as a backup. I did notice that the Recipient Update Services are pointing to this old server. Can I change the Exchange server in the Recipient Update Service to one of the other newer servers with causing a problem? If I can just change the server, should I "Update Now" or "Rebuild" right after.
I appreciate any help you can give.
