I am having issues with autodiscover on a new computer I am setting up. The process of setting up a MAPI account on Outlook 2016 on Windows 11 in my environment seemed successful after I walked away for about 15 minutes. I had to provide credentials multiple time but it does now come up and appears to be connected. However it now is asking if it is ok for autodiscover to make changes to the configuration. Other than upgrading to build 8839 no other changes to the mail server or dns server configurations have occurred. I'm struggling to figure out what isn't working anymore.
I ran the Microsoft Connectivity Analyzer and got the following ugly results:
