I am in the process of migrating mailboxes from Exchange 2010 to Exchange 2013. We use Outlook 2013 and can connect to mailboxes on Exchange 2010 with no issue. The problem is that when I migrate the mailbox to the DB on Exchange 2013 Outlook does not redirect Outlook to the new server. If outlook is open when the move is complete a message "The Exchange administrator has made a change that requires you to restart outlook". Upon reopening Outlook a prompt for credentials appears and even though I put the right username/password it keeps promtpting. If I hit cancel I get the "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete" message. Everything passes in the RPC/HTTP connectivity test at testconnectivity.microsoft.com. Not sure what to do at this point. Any help would be much appreciated.
-OWA works
- ActiveSync works
