I had this issue before with users getting an error that the exchange server is unavailable and the event logs show they have "too many sessions" open. The problem was resolved with the netsh tcpchimney disable command. That resolved it instantly for the affected users. However now I have one user who is still having this problem from time to time. I know of no way to remove her login sessions except to reboot the exchange server, and I am not going to do that for one user unless it's the president of the organization! Has anyone else encountered this problem and found a way to remove the excess login sessions? Moving her mailbox does work, but then she is without any email for about an hour. Exchange 2007 SP1 rollup 6. She has no open outlook sessions on any computer and it still shows 34 logins on the server.
