Forgot which Microsoft account I migrated my Mojang account to

On the same email account? Yes I have both emails available.

Hello Lucas thanks for getting back, I migrated my Mojang account to my Microsoft account in 2021 but continued to use my Mojang account to log in which worked fine until very recently when i tried playing again. When I try logging into my Microsoft account I thought was attached to it back in 2021 it says I don't own the game. I tried using my older account thinking maybe I had migrated it to the wrong one or something but it also said I don't own it on that account either.
After about a week of going back and forth between Mojang support they informed me they couldn't look at Microsoft accounts and all they knew was I was signed into the wrong one. They then told me that I need to contact microsoft support which brings me to today.
The aggravating part of this is I still have the original purchase email as well as the migration email which conveniently leaves out which account I migrated to. Any help would be appreciated at this point.

Thank you for your time,
-Ian

Hello, ippyk. Thanks for reaching out! My name is Lucas. I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

You mentioned that "Recently they have stopped letting me sign in". Would you please explain better so I can proper understand?

Were you already signing in with a Microsoft account to the Minecraft website and to the game and then it stopped working? Or were you signing in with your Mojang account (not migrated yet)?

Microsoft has a "Contact us" button at the bottom of their website but I'm pretty sure no Microsoft employee will tell you what Microsoft account is migrated from a Mojang account.

Waiting for your kind reply.

Thanks for sharing all this information. Do you have the purchase email for Minecraft and the migration email on the same account?

May I know if you purchased Minecraft Java or Minecraft for Windows? If you purchased Minecraft for Windows, is the order showing as completed on your Microsoft order history?

I ask this because if you actually purchased Minecraft Java, since the payment processing and licensing were all done by Mojang, it is their responsability to give you the game.

If you purchased Minecraft for Windows (which were being sold at the Microsoft Store), Microsoft is the one responsible for the game licensing. But, if the order is showing on your order history as completed - which means Microsoft is actually recognizing the order and giving you the game license - then Mojang is the one who is responsible for giving the game for you, since on Microsoft's side everything is normal.

So, the only case that Microsoft support would be able to assist you with this is if you actually purchased Minecraft for Windows, on the Microsoft Store, you received the order confirmation email but the order is not showing on your Microsoft account order history page (https://account.microsoft.com/billing/orders).

All the other case cenarios should be handled by Mojang support. And if they say they cannot help you (which they should be able to do), unfortunately nothing can be done. I'm really sorry about this.

Feel free to ask back any questions, my friend. I'm here for you.
