Had Small Business Server 2003. Moving to Hosted Exchange. Autodiscover record points to Hosted Exchange. We are able to setup a new profile in Outlook for the hosted exchange mailbox.
When we open the new profile, we are prompted for the password for the hosted exchange mailbox. It accepts it and status of Outlook changes to 'Connected to Exchange'. After a minute or two, the status changes to 'Trying to connect to Microsoft Exchange' and we get another prompt for credentials. However, the credentials it is looking for are for the Small Business Server.
Also, it appears that we never get disconnected from Hosted Exchange because we can still send a receive mail. Just can't figure out why it is trying to make a connection to the old server.
