I posted something about a month ago about this....thought it was some kind of flook. I was pointed to the "recover deleted items" under the "tool" menu and was able to recover this users emails. However this has happened two more times since then. As far as i know there are no size limitations on the mailboxes at exchange. I have looked over rules and properties on this users account in outlook. Nothing set up there. They are archiving but only "sent items". This is only happening to the "inbox"...none of his other folders are being affected. It is happening anywhere from 7 to 9 PM when no one is working at that location. The inbox email do not go into deleted items they go straight past it. This does not make any sense to me. Anyone have any ideas.
