We are currently using CM 7.1.2.20000-2 (will be upgrading to CM 7.1(3) in a couple weeks), Presence Presence 7.0(2), and Exchange 2003 R2. We recently set up the Outlook Calendar integration with Presence and users are not able to change their status in Presence, when a meeting has ended early, without either deleting the calendar entry or changing the time for the meeting.
Thanks!
