Accepting the original meeting invitation on the server synchronizes the calendar event to the device.
Accepting a change (in description, notes, location, time, etc.) to the original meeting invitation event on the server, synchronizes the changed event to the device.  This results in the meeting invitation event appearing twice on the device since a change/delete for the original calendar event is not sent
