My clients are running Windows 7 x64 and Outlook 2010. My servers are running Windows Server 2012 R2 in addition to Exchange Server 2013 CU15.
I had some major problems with my Exchange 2013 installation, such as Service Error 503 in the ECP and various other errors in the Event Viewer, so I decided to reinstall Exchange. I already did this in a test environment and I replicated the same procedure in my production environment today but there is a problem.
My procedure was as follows:
- Create a new VM running Windows Server 2012 R2 + Exchange Server 2013 CU15
- Migrate mailboxes from old to new server using the ECP > Migration method
- Uninstall Exchange 2013 from the old server
- Shutdown the old server and remove from the AD including all DNS entries
- Delete client Outlook profile, recreate and restart Outlook
Outlook has downloaded the mailbox fine and I can send/receive emails using Outlook and via my iPhone without an issue.
However when I first open Outlook, it says "trying to connect" for what seems like a good minute or so. Using CTRL and right-clicking the Outlook tray icon, followed by Connection Status, it lists all the connections; there are 4 connections (1x Directory and 3x Mail), except one of the Mail connections has a different server name to the other two. Despite this, it says all connections have been established, but I wondering whether this other server name is the old server and could this be causing the delay to connect each time?
