Even if I've set a start and end time for an Out Of Office message to be sent, every time I start up Outlook while I'm on vacation, the silly "Out of Office messages are still on.  Do you want to turn them off?" dialog.  If I have Outlook open for some long amount of time (hours, not days), the dialog again pops up.  The problem is, many automated tasks (my spam filter, updating the items badge in the dock, &c.) do not work while the popup dialog is present.

Is there a way to disable this popup dialog "feature"?  I don't want the Out Of Office message off... that's why I set a start and end time!!
