We have found this new problem when migrating a client from Google Suite over to Office 365, affecting mainly the Outlook service. Back in the day, just pointing the autodiscovery CNAME record would do the trick. Nowadays, they base this on a secondary service that was called ampli.net, nowadays outlookmobile.com.
