Autodiscover issues after upgrading from exchange 2013 to 2019
2019 is up and running. 2 servers in a DAG with full creative originality in the naming of exchmb1 and exchmb2. I have not moved all mailboxes yet from the old 2013 server. I have moved some of the affected mailboxes from the old servers to the new servers with no change in the end result.
Most users are connected and working fine, but about 100 or so out of 1100 plus will not connect.
I can ping autodiscover.domain.com and mail.domainname.com and they resolve to the correct servers just fine from these machines but outlook will not connect.
They are windows 7 machines. that originally had office 2010. they now have 2016.
domain firewall is turned off and all antivirus is uninstalled.
Outlook gives the error message "Log onto Exchange ActiveSync mail server (EAS): The server cannot be found."
I have read this article stating that EAS isn't supported, but that is the ONLY option to install.

I have tried to use this article which tries to oversimplify it, but get the same result and same error message.

Pulling my hair out here. Thanks in advance for any tips...
