I am in the process of migrating from exchange 2007 on server 2008 to exchange 2013 on server 2008 r2. So far the install and migration was going without issue. I have moved the majority of the mailboxes to the new database and the move is going without issue.
Outlook anywhere is working from outside of the office and phones are syncing without issue.
The issue I am having is the local Outlook clients will not work. When I open them up I expected them to switch to the new server like in previous exchange migrations but they just give me a username and password prompt and won't take any credentials.
I blew away one of the Outlook profiles and it won't let me create a new one, I get the same username and password.
I have switch the internal url for autodiscovery back and forth between server.domain.local and mail.domain.com and tried many combinations with no success. I have already applied a cert for mail.domain.com from godaddy to everything except for UM.
The users are a mix of Outlook 2007 and 2010 (fully patched)
Any help would be great!
