Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Over two years later and NO REAL SOLUTION TO THIS PROBLEM!
I tried the password reset process and they asked me to provide a bunch of information I didn't really have. My kid doesn't send emails! He's not even 10 years old! I just made the stupid email account because that's the only way I could redeem a stupid minecoin card. Microsoft made my kid cry because he's had the card for over two weeks and I still don't have access to his account to be able to enter the code!
How freaking hard would it have been to provide a password reset option for Family Group managers or at least asking for the parent to sign-in to allow the reset to go through? And to top it all off Microsoft makes it as hard as any other billion-dollar company to find any kind of support number or email to resolve the issue!
Edit: Oh, I thought I was done complaining, but not even close! Despite the fact that my account and my child's account are in a Family Group, their knowledge article states that if I don't know pretty much all of the details about an account I made solely because I was forced to make one for a kids game then I'm SOL! That account is trash and can never be used by anyone unless I miraculously remember the password (which won't happen because I always make highly secure passwords)!
