Out of the frying pan and into the fire. Of course, I'm being a little flippant, but the MS ecosystem is not without its problems. A colleague has 3 MS accounts for dealing with 3 different things (a government contract, a 3rd party company contract, our company account). Because of this, he was in hell for days because of some fubar on the MS side. I have (seemingly!) different MS accounts, for Azure development and Office 365 and I am regularly confused by the various MS websites.
MS Azure accounts always seemed odd and overly convoluted to me. I had an issue with my personal Microsoft account where I couldn’t sign up for an Azure trial (wanted to kick the tires on Codespaces before it moved to GitHub). Turned out, my account got associated to my kids’ schools MS account because that email address was on a school mailing list. That was a pain (and many hours) to get figured out.
my friends that have one MS/Outlook account at their jobs, which have enterprise support reps for their big enterprise accounts sometimes have multi-day lockout for unknown reason, 2FA failure for days, absurd issues with timezones being inconsistent across MS services, etc.
