Outlook leaves logon sessions on Exchange

I have a problem with a setup where the number of logons (Shown under Mailbox Store) listed against a particular user keeps increasing until Outlook will no longer connect to the server. Restarting the Information Store cleare all the logins and he can then reconnect.
He connects using RPC over HTTPS, but at the moment is the only one connecting remotely, so I don't know if it's user specific or RPC.
I can check later, but I'll post now incase someone knows the answer.

Sounds like TCP Chimney strikes again.

Make sure the server has the latest drivers, most of the major vendors (Broadcom, Intel etc) now have updated drivers to deal with this issue. Or just disable TCP Chimney.

I have also seen this on a few occasions caused by a firewall tearing down the session incorrectly or in a way that Exchange doesn't recognise and the session stays running. A firmware update on the firewall fixed the problem.
