dear support, 

I got 3003 error when tried to cancel a recursive meeting in outlook which was created by our service account, but I can cancel occurrence one while cannot cancel the series one. please help.

This is the exact issue I am having. The meeting is recurrent but I would like to now cancel the series and I cannot. I can only cancel the calls one at a time. This is not a solution as the number of emails will cause mass confusion.
