Family Setting in Outlook is not working

My child tries to access his email account and gets this message: Your account is not ready It looks like your parent hasn't finished setting up the Family Safety settings for your account. Click "Go to Family Safety settings" to finish the process and get into your account.

We go to Family Settings as indicated and this is the Error message:

The page you have requested does not exist, has moved, or is temporarily down.

Thank you.
