Knowing the email address is the most important thing to recovering your Xbox account. For security reasons, not even customer support will reveal the email address.

Look here on the
Forgot the Microsoft Account Email Solution and prepare to do a little "sleuthing" to figure out what that email address was. Consider also checking your personal files, records, or other email inboxes to see if anything has any relation to that old email
address.

Hello, first it's a pleasure to be able to help you today.

Xbox Support can’t provide this information, even if you know your Gamertag.

Well, maybe I dont tell exactly my problem. I try it with other words:

I bought the game with my regular email adress. That ist the email adress I also use to login in my microsoft account and I still use this email adress.

Somehow (and I dont know why it is so) I have now another gamertag but i still use the same email adress.

Because of this, I cannot login in another way in my microsoft account.

The game I bought (Minecraft) seems to be linked to my old gamertag.

I hope that someone from microsoft can look in my account details and fix this problem, because it is not very cool to buy a game and than have no access to this game

Greetings,

Christoph

I've done all stages, deleted cache, rebootet, unistall and install again but my old email adress keeps coming up when i try to login in Minecraft launcher.
I can't change that email adress to my active email.
Minecraft is bought trough Microsoft Store with my active email adress.

What should i do?
