Forgot my password and email after being offline for 3 years

Hi okBoomer9, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

To access your Xbox account and other Microsoft services, you need to know the email address and password you used to set up your Microsoft account. Xbox Support can’t provide this information, even if you know your Gamertag.

This means that we need to locate the Microsoft email address first then we will proceed with attempting to recover it.

I got you here a link where you can check methods available in locating the email address that you used previously.

Here you go: https://support.xbox.com/en-US/help/account-pro...

I mean my other account

Well if you remember your actual email address password but just don't remember your xbox account password then your in luck. Go to microsoft.com and click on sign in and then click on forgot password. It should send something to your actual email address
so you can reset your password and verify some stuff. Then once you get your account back while still on microsoft's website I suggest adding some proofs to your account like your phone number and alternate email address just to be proactive if anything like
this happens again. Hopefully this helps you.

Well, unfortunately, you have to use your Windows Live ID (now called Microsoft Account ID) to get your account back. I would suggest contacting Xbox Customer Support by phone preferably, since you can't access your account there's no need to go to chat.
The phone number is 800-469-9269 if you're US/Canada. Explain to them what's going on and they can give you the best course of action. If you got an email from the form you filled out saying that there was a code on it I suggest keeping it handy.

Hi there,

contacting Xbox Support won't help, because this is an Microsoft Account issue, the only steps available to try and reset the password or to recover the account are mentioned on this link:

support.xbox.com/.../forgot-microsoft-account-password

If both of those fail, there is not mucht left to try...
