Exchange 2007 to 2013 Co-Existence Issues
Posted on 2014-11-24
I am in the middle of migrating from 2007 to 2013. Both servers are up and running. I have mail flowing between them successfully, as well as out to the internet. I have moved a few users from 2007 to 2013. My question is once I moved the user mailbox the server name in Outlook changes to a weird name (not the new server name as I would expect). It prompts for Outlook to close and then re-open.... and then asks for credentials..... and then connects. When I go to the server settings I see the server name changed, but it looks like a crazy Hex thing....
What is that? and will it change again once I remove the old exchange server from the Org? Why prompting for credentials?
