Changing a Microsoft account from an (incorrectly entered) adult birthdate to the correct child's birthdate

The links provided in the above response pertain to an account which is already setup as a child. That is not my situation.

My issue is going from an ADULT account to a CHILD account. Currently, the account is setup (incorrectly) as an adult account. I would like to update the birthdate to reflect that this is a child account.

This is an easy scenario to test:

• Setup a new Microsoft account with a birthdate that makes you an adult.
• Log off and then log back in
• Go to your profile and attempt to change the birth date to make you a child.
• The system will prevent you from making this change.

Any suggestions?
