I have an Exchange 2010 SP1 server that I migrated all my users over to from version 2003. I am preping my old 2003 server to be removed from my network. As a test I have shutdown my 2003 server to see the effects it would have. As soon as I shut down the old 2003 server I have users that go offline. If you open Outlook you get an error that says that the server is unavailalbe.
I saw the issue posted here:
My Exchange 2010 SP1 server is set to Encryption Required = False. My users are on Outlook 2010. Their profile is set to encrypt data between Microsoft Outlook and Microsoft Exchange.
Any ideas why this is occuring? Thanks for your help
