Re: You are not allowed to access online features on xbox one

I read somewhere of a solution and it worked for me.

I went into my sons Microsoft account, not on the xbox but on the website, there I was able to change his date of birth. Once it was saved I logged back into the xbox loaded his profile and Star Wars connected straight away. One happy little fella.

In order to find the email address associated with his account I opened his profile on the Xbox and in Settings, Sign in, Security & Passkey option. I found the email address.
Once I had the address I logged into his Microsoft Account and under Your Profile, Edit Personal Info I was able to change his Date of Birth.

Hope this helps and works for everyone else.
