Can anyone tell me why my deleted items box may have disappeared? Not just the messages, but the whole folder. I didn't think Outlook would let you delete that. I'd like to have it back. Any suggestions will be appreciated.

Have you tried the Diagnose and Repair option in Office?

Meh... apparently, somehow the darn thing was set to "hidden"... and, of course, since I couldn't see it, I didn't even think of this. I turned on "show hidden files and folders" and there it was!!!! Unhid the thing and it showed right up. Thx though.
