Forget across services, I somehow have at least three Microsoft accounts all tied to the same email address, with no way to know which account any particular service wants on any given day. Teams is particularly bad, signing me into one of the three seemingly at random so that I have to keep logging out and back in until it miraculously gets me into the correct account, guessing which password it wants each time. Any support avenue I’ve tried has no idea what I’m talking about and offers no fix. Thankfully I don’t much rely on my Microsoft accounts.
