Why was my family member's account locked?

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

By locked, may I ask what is the exact error message that your family member is getting whenever he/she is signing in to https://account.microsoft.com?

Hi. My name is Brilliant and I am happy to assist you today.

Unfortunately only organizers of a family group can remove family members. Only the adult who granted consent can remove a child account from the family group. If the adult cannot access their account, the adult or appropriate guardian should attempt to recover the adult account. If you're locked in a family group, then your account may be lost forever.

Yes, what I tried was the alias of the Microsoft account, but the detail is that the family member's account is associated with Facebook and other things, so I can't delete that account and use the personal, and having the two accounts, mine and that of
my family member, because the information is linked and what I want is to separate the family account from everything that has to do with xbox, to be able to use my personal account, because I have problems because when I change the name in the xbox live account,
the name is changed in the mail of my family member, and because it generates problems, I don't know if there is a way to separate the account from this family member and not have it as an alias or as a principal.

Two ways to tell if he is in a family as a child account already.

Sign into his account at account.microsoft.com/family if there is no other family members then he is an adult in his own family.

Sign into his account on the xbox console go into settings and under the account tab go to family settings and go down to manage family members and it will tell you if there are any family members in the family there.

Hi Chris,

Thanks for reading my post.

I believe Mojang was contacted through Minecraft.net which we were informed that this was not their problem since everything has been migrated over to Microsoft. The issue is that we cannot log into (name of family member's) Microsoft account through the Microsoft webpage log in or Minecraft client due to the account being locked due to who knows what.

Every time I buy a PC with Windows I need to create a new Microsoft account because as soon as the account is created I am immediately locked out of it. So I know this issue is a very common one that should have an answer but I cannot find it.

We just need stable access to this account so that (family member) can continue to enjoy this service.
