I have a user that joined the company earlier this year. She sends out a lot of meeting planner requests. Ever since she started she has been receiving a ton of Emails that read "Microsoft Outlook on behalf of" XXXuser. The users are varied but they are all part of the same group that she has sent the meeting request to. They all come at the same time and they automatically get pushed into deleted items folder.
The only thing I have been able to find out is that the time she receives these message coincide with the time of day that my exchange server was rebooted. For instance I just installed CU10 and rebooted the server at about 5pm and that is when her messages are coming.
I have no idea what is causing this and not really sure where to look. She is the only person in my company who is experiencing this.. Can someone please shed some light on this..She has no rules set up and we have an onsite exchange Server not Office 365.
Thanks
