I have some clients that are getting randomly disconnected from the exchange server. (Exchange is running Exchange 2010 on Server 2008 R2). does not seem to matter if they are in cache mode or not. They will get password challenged by there outlook (office 2010) and when they type there password in the box it does not go away. They have to shut outlook down and restart it. It will then connect with no issues for any given period of time. No synch errors in the log, the event just shows that connection to the exchange server has been lost and will connect back once available. However, a quick shutdown of outlook and restart fixes the issue. I have checked to see if it is on 32 bit or 64 bit, problem has happened on both types. I have checked antivirus by disabling and still happens. Any idea's?
Thanks
