Forgot email address, it was only created to purchase Minecraft and nothing else.

Hi PrimusWren, 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 regards to your concern.

I apologize but that will be the only way or option to recover the account. If you can use a device where you previously signed in to the account that may help but other than that, other information needs to be filled up accurately.

Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I'm afraid only way to recover an Xbox account is via the account recovery form here https://account.live.com/password/reset

You can try all the emails you remember or if you had a phone number attached to the account, you can use that too.

Unfortunately, an account cannot be recovered using the gamertag alone nor the card details.

Unfortunately without knowing the email address there would be no way to recover the account. Due to security and privacy reasons Microsoft wont tell you the email.

In these cases youll basically have to look through all the email accounts you can think of that you own to narrow down and find out which one is the one you made your minecraft account with.

so the ones who have multiple email addresses use one address online for LIVE and nothing else? thats the only email address you put on the internet for is the one for LIVE and the other things that require an email address is for other things?

Please be aware that it is also possible that you accidentally created this account on your email address. More people than you think do this accidentally without realizing that they have done it.

This is the most likely reason if nothing else relating to your email address has been accessed. Remember, to create a gamertag they would need to know both the email and password.
