Nikitha-MSFT , thanks for checking.We found an issue performing with update as belowUpdating the attendees for the event replaces the previous attendees and not adds them into invite

Niketa_Mane&nbsp;_ when you update the attendees you need to add all the attendees - update&nbsp; attendees will be replaces with the new attendees. This is by design.
