Hi priyamshah1, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

Just a friendly reminder though that on our Microsoft account we don't have an option to check what in-game account it is linked to. This means that you may need to reach out to Mojang in that way they can validate it for you.

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?
