S4B Update Tool wreaking havoc

[Peter Rininsland]

I have a pretty weird thing driving me nuts. I setup a recurring meeting as a chair the other day. Once I got the PSTN calling feature enabled for my conference account I used the S4B Update tool to update this meeting. When I later wanted to delete it that worked pretty fine in the first place. But a while later it was back. Invitees of this meeting tried to do the same and failed as well. Meeting just comes back.

Any idea how I could eventually get rid of that meeting? Could it be related to me using the update tool for it previously?

I'd investigate the exhcange calendar helper. If necessary, open a service request for Office 365 or premier case. removed meetings should be cleared, but agents on Exchange can sometimes "help" and bring them back due to thinking you accidentally removed them.
