Who on actual planet Earth decided that a good workflow is: 1. Receive an invitation to a meeting 2. RSVP "Accept" that meeting 3. Automatically move the meeting invitation to the Deleted folder _AND MARK IT AS UNREAD_ That 3. is the reason why everyone hates Microsoft. No one — absolutely no one — needs an unread item in their deleted folder, let alone something they have already accepted and added to their calendar.
