I have everything up and working for the old server but when I migrated my mailbox to 2013 Outlook can't connect. When looking at the connection status it is still looking at "legacy.domain.com". So it appears it isn't picking up the new information after the migration.
I am external and currently only have the SRV record configured (not autodiscover A host or CNAME).
How do I troubleshoot this? I'm using Outlook 2013
