I am having an issue with microsoft exchange now. We have Exchange running and connected through the VPN. The user can load outlook and they will automatically be connected to their account.
The user can connect just fine and get the "connected to microsoft exchange" message but from time to time it will say "need password". When this happens a user is prompt to enter a username and password and clicks remember my password. Everything is entered correctly but it does not save anything.
Here is the kicker, emails still come in with no issues but the problem goes away for a few seconds if the user clicks on cancel instead of ok in the user/password prompt.
