We have moved our first couple users over as a test.
Autodiscover is not working us. It worked fine yesterda. No changes were made and now it doesnt work upon trying to migrate users.
Some users connect and work fine, then if they close and reopen outlook they dont work.
I have all the required settings from microsoft in external dns.
I am not sure what to try next as there is not a whole lot out there that I can find that applies to this situation.
