Thank you. 0 Cayenne OP Breakingcustom Nov 23, 2012 at 11:34 UTC I have Exchange 2003 and I have ran into this. Basically what I had to do was open up TCPView and get the IP address of the end-users machine and see how many sessions they have open. I always make sure wifi does not connect by default and if they have their phone or tablet as well all create sessions. Once I find the IP, I delete all the sessions and reopen Outlook and they are back up and running. 0 Pimiento OP Artiomm Nov 24, 2012 at 7:17 UTC You are right. But the problem returns after some time. 0 Habanero
