Wait - are you saying both the start & end dates are set for last November (11/2009)? If so then there should not be an out of office message sent in this case.
Unless the current date is between the start & end date, then the log will show "outofoffice not sent (until date reached)".
If you have an account which has an active out of office message, and such a message is not shown between the set dates, can you show us the log for such a message?
