Had a go. Last night disabled one server to no allow any logons. It flushed, and sat in my environment this morning with 0 sessions.
Step 1: Open desktop as an administrative user, start Outlook and see about the problem - Sadly, still there. I verified I was the only user on the system at that point.
Step 2: Start Outlook as a user through Citrix, and see about the problem. I logged on, found a couple of other users had logged on to that server in the short timeframe I was working, booted them off so I was the only one on the system, logged out the Administrative user I was logged in as, and saw about the problem. Still the problem persists.
Said hotfix doesn't seem like it will solve the issue for me
Further suggestions are welcome!
