Exchange Server 2010 Server is Unavailable

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:
http://support.microsoft.com/kb/2006508

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

For starters, install SP 2 for exchange and let your users stay on the old exchange server until it's upgraded...

Sorry, I meant on your exchange server...Your Exchange is SP1 ?  Install SP 2 on the exchange server

Paul can you explain why this is occuring only when my Exchange 2003 is down. All my clients profiles point to the 2010 server. All is migrated over. All my roles are migrated over etc. What function in Outlook causes the client to still rely on 2003? How can I diagnose that?

PaulD77Commented:
well let me ask is this only on a few clients?  or your whole organization?  If it's a few clients, go to one and double check where their outlook is pointing to to find the Exchange Server...

Is it looking for your new 2010 servername and yopu're still getting this error?

Yes. All my clients point to my new Exchange server. It occurs with all my clients.

Are you able to connect via outlook web ap with the old server down?

There has to be a legacy issue if your whole organization goes down...

1.  Hold down Ctrl and Right Click the Outlook icon in the Notification Area, select "Connection Status...".  
2. Under the Server Name column, is your Exchange 2003 or your Exchange 2010 listed?

In particular, make sure your Public Folders and OAB are moved over.  Make sure you dismount the old Inf Store and public folders before you mount the new Database and public folders

David, yes everything points to my new server. I also did a manual autodiscover test and all points to the new server. My new server passes all the tests at testexchangeconnectivity.com with no errors.

When your exchange 2003 server is shut down.

Connect to connection status, where you will see TYPE.

Does it say connection etc., for one type of connection.

Is it directory, pf or mail.

Also is your exchange 2003 holding any DC GC roles.

I think the issue is mail profile related. Some of my users have two email profiles, Exchange and BACKUP of Exchange. When I take down the old email server I cant open their profile Exchange to view or edit it. When I startup my old email server the profile will open. I have deleted both profiles and recreated a new profile and that seems to solve my issue.

Issue was profile related. I deleted the profiles and recreated the profiles.
