Change XBL account from child account to adult account

A child account will not be promoted to an adult account until the 18th birthday of the account holder. The is no way to change the birthdate on an XBL account.

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

I apologize but that’s not possible.

Its not possible to change from an organizer (adult account) to a member (child account). Whether the account is an adult account or child account is dependent on the date of birth entered when the account was first created. The date of birth on the Xbox
account cannot be changed either.

Hey Xwarrior,

Did this account graduate naturally from a child account to an adult account or was there a birthday change attempt? You can change the birthdate to the Microsoft account but it will not change the birthdate that was entered originally to the Xbox profile.

In other words, a child account will remain a child account until it graduates naturally to an adult account. No way around it.

So, if I understand, you account is an child account and you want to unlink your parent's account from yours? Unfortunately, child account are not allowed to be managed without and adult account attached, you can ask yours parent's (adult account owner)
to contact support and ask for a change of adult account, re-alocating the child account to another MSA adult
