Out Of Office WIERD BEHVIOR

Hello everyone,

I’m running Ex2003 SP1.

Here’s a wierd situation that I am looking for a solution-

Buddy is in the office.
Deonna is NOT / her out of office is turned on.

Buddy’s wife emails Buddy (a meeting request) and she recieves an email OUT OF OFFICE REPLY FROM Deonna!!

How does this happen??? Anyone have any ideas???
