On our old exchange 2003 server we used to be able (I'm not sure how as the previous admin set this up) to stop externally forawrded emails from getting Out of Office replies.
So this being the scenario;
User A has all email copied to user B, User B set their Out of Office and on the old server anyone sending a message to User A would NOT get User B's Out of Office.
On the new server they do.
Any ideas on how this could be achieved?
