Lets say you schedule an ad-hoc meeting because you're on a call with a client. You setup a 1hr meeting that eventually goes for 3 hours. There's nothing in the activity history to show that meeting duration but what's more, the calendar didn't readjust to suit the actual duration of the meeting.

Performing this adds major benefits to us, in that client meetings may go over time, but if that meeting which is a support call extends, then this should increase the billable time for a case or work order in Dynamics. Without integrating directly (regardless of the integration), auto-extending the calendar appointment to the REAL start and end times can also show managers how much overtime (or under time) the meeting went for.
