Error on accessing outlook.com from the Family Safety Account: “Your account is not ready…. It looks like your parent hasn’t finished …..”

My son is trying to access the outlook.com. His account ( @live.com) is under the family safety.

After typing the user name and password, he gets an error 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." 

And clicking on the link takes him/me to "The page you have requested does not exist, has moved, or is temporarily down."

I removed the web filtering from his account by logging in using my account but it did not solve the problem for him.
