Hi all..... I have just come across the weirdest Exchange 2010 problem I've ever heard of...... I have a user (user A)..... When any other user on this exchange server puts on their Out of Office.... user A starts to receive their email..... The messages arent being forwarded from originating user..... User A is getting external emails delivered to his inbox, that are addressed to other users. So emails get delivered to both the addressed users (who has out of office turned on) and to user A..... For no apparent reason. I wouldnt even know where to begin with this problem. Has anyone seen this problem before? TIA, dekkar

Did he create a forwarding rule under Out of Office?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Did you check the transport rules?

Are you sure the user isn't an alternate recipient of the primary mailbox?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."
