@MojangSupport Hello, I need help about my Minecraft Account. I would like to revoke the migration of my Mojang Premium account to a Microsoft account.

Unfortunately, the migration cannot be reverted, and we are unable to transfer games between Microsoft accounts. Can you tell us a bit more about the issue you're having so we can point you to the right team for support? ^AM

I just lost the access of the Microsoft Account who it was transfered, so I just cannot login it. And it was not me who has did the transfer at my microsoft account.
