Outlook 2K3 sending items to delete box.

Has anyone came across the problem of outlook automatically deleting items in inbox, whether read or unread? I have a machine that is doing that. It looked as if it was a task that was scheduled, but when I looked in the tasks there was nothing there. I also went through all of the settings and nothing jumped out at me. I’ve a virus check and nothing was found. Anyone have any clues as to what it could be?
