Hi @mwell ,
Welcome to our forum!
How did you update a single occurrence of the meeting?
Based on my test, i found that when i try to update a single occurrence of the meeting, i can find the person who was forwarded to is placed in the Optional field. And after i send the update message, the updated single occurrence of the meeting is both displayed in the calendar of the meeting recipients and the person who was forwarded to.
So please check Optional field before you sent the meeting update messages.
