Hello! Anyone else having issues with Outlook Autodiscovery (for current versions, Outlook New for Windows, Outlook for Mac and Outlook for Mobile)? Axigens documentation for this isn’t exactly clear or up to date, and for Outlook only references 2016 which is quite old now. Outlook seems to use now use autodiscover.json and autodiscover.xml but with additional queries as a post request and things know (honestly not sure, Microsofts docs aren’t exactly clear on this).
That said, watching everything.log, I can see basic autodiscover.xml attempts from Microsoft are being given a 501 Not Impemented.
Can anyone clarify the required setup subdomains/DNS Records for Autodiscovery to work with Outlook nowadays? I’ve gotten it working before - does the AutodiscoveryParams have to use subdomains, i.e autodiscover.axigentesting.xyz or imap.axigentesting.xyz - or can I just use the root domain?
