Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I am experiencing the same issue and have just gotten off of the phone with Microsoft. The only solution that I was provided was to send an email with feedback on my issue and wait for a response, which is pathetic. I do recall this issue happening when Hotmail users were forced to switch to an outlook domain in order to log in, but can't recall how it was resolved. You would think that since this has happened in the past that Microsoft would keep this on their radar when doing future updates, but that would make too much sense.
