Recovering an account without an email

There is but you gotta remember enough details of your account to pass PII

Reset or recover your Microsoft account password

Go to the above site and follow the instructions there you can recover the account without knowing the email etc. Once you recover your account and can get back in you should then be able to see what your child's account email is under the family feature.

Since it's an online account and not offline, you could recover it without a 360 console, but you would need the email.

If your account has been inactive for over 2 years it may have been deleted. For general consumer accounts, Microsoft only retains inactive accounts if:

• you have an outstanding amount payable.
  
• you have a positive account balance.
  
• you have purchased digital licenses associated with the account.
  

That said, your only option for account recovery is the recovery form. You do not need access to any specific e-mail address for the recovery process, you just need to nominate an address at which you are contactable and supply sufficient information to validate your account ownership. If you do not at least know the Microsoft Account's e-mail address though, you have no avenue to recover the account.

Hi there! This is Ronnie, an independent advisor.

Nice to meet you and I hope you are having a great day!

I understand you need help recovering your account.

If you forgot the email to your account, you can try recovering that here:

https://account.live.com/username/recover

If you are trying to recover the account but do not have access to the security proofs from the account, you can use the recovery form:

https://account.live.com/acsr

Just a heads up that recovering an account email needs to have access to the security proofs that the email has because without access to those information, it will be difficult to recover the username.
