Thoughts on this one?

User A created two meetings on shared calendar A. She created the meetings from shared calendar B. People were invited to attend and they accepted and then she later canceled the meetings but they were only removed from shared calendar B, they are still showing up on A and the calendars of the other users who accepted and cannot be deleted from the other calendars by those users.

Will the meeting need to be deleted by an Exchange admin?

Thanks!

Kevin
