We have recently upgraded to exchange 2013 running on server 2012 R2.
I have 2 identical exchange servers for high availability.
I am able to manually set the outlook profile correctly and successfully connect to Exchange.
When I exit Outlook and try to restart it outlook fails to connect.
When I go back and look at the profile some thing has changed the profile some times the authentication method has changed some times the proxy server name has changed.
I have to go back and remove the profile and create a new profile, and the user is able to log in again successfully.
The work stations are running windows 7 processional 64 bit.
Any ideas will be greatly appreciated.
