Duplicate Appointments on Update RRS feed

  • Question

  • New and strange behavior when updating a meeting. 

    Within my Outlook add-in I make a minor change to an existing appointment (does not appear to matter what the change is) and save and send the updated appointment.  On resend, I have verified that the GlobalAppointmentID is the same as the orig appointment.  I now see two appointments side-by-side in my calendar. 

    Sometimes, this resolves itself over time.  For example, in my last test I logged-in as the invited user, accepted the updated appointment, logged back in as the sender and waited for Outlook to synch with exchange.  At this point, the second appointment had disappeared.  Sometimes, both appointments remain, which may simply be a synch timing issue.

    Can anyone shed light on what I'm seeing and why?
