Duplicate Appointments on Update

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?

Thanks.

Answer 1

I wrote VBA Outlook code to eliminate duplicate.

If you want to delite your downloaded messages without instal addins that: 

• Simple Export poprzez makro jako metoda na duplikaty wiadomości
• More experienced Usunięcie duplikatów
  

 

Use translator if you want to know more.
