Ok, I'll try to explain the issue as thoroughly as I can. There is a meeting request that a users account seems to be sending out. The user did not create the meeting but is somehow a delegate. This meeting delegation seems to have jumped around to different users. For example, user C is the delegate now and his account is sending out the email. Before it was user B for a few months. Before user B, User A's account was the one sending out the requests. My guess is that someone who does not work here anymore created the meeting but no one know's who that was. Users A,B,and C have all deleted the meeting from their respective calendars but it does not seem to matter. Whomever's account is sending the meetings, their inbox get's flooded with decline meeting because everyone knows this meeting is rogue. Does anyone know how I can stop this? Any help would be appreciated.
We are using Exchange 2010 now. We were on Exchange 2007 when this begun.
User A is Outlook 2010
User B is Outlook 2007
User C is Outlook for Mac 2011
