I have a user that is constantly being disconnected from our Exchange server at random times. The user will be working just fine in Outlook and periodically they will show up as "Disconnected" from the Exchange environment. I have been unable to pinpoint why exactly this user is having this issue. There isn't anything out of the ordinary with this user aside from they had a name change years ago. They state that the problem started a while after so I'm not sure this is related.
I'm not entirely sure where to start to get more information to pinpoint the issue.
Here is what I have looked at:
1. Event Viewer - nothing out of the ordinary and no particular errors that would direct me to a solution.
2. Reinstalled Outlook
3. Moved user to a completely different machine - Same problem occurs.
4. Removed SMTP Exchange address for their previous name.
5. Ping test Exchange server - clean
6. Trace Route - Clean
Windows 7 Professional - Microsoft Office 2010 Professional
