Any ways to recover a minecraft account that got hacked and migrated to a microsoft account...

Yes, unfortunately that’s the case
If maybe the hacked account was a Microsoft account, you could try to recover it

But as the hacker stole your Minecraft and then they migrated the account to a new Microsoft account
There is no way to know (from Microsoft side) which was the account used to migrate this Minecraft account
They only have the tools to work with Microsoft accounts

If you migrated Minecraft to your Microsoft account, and it was this account that was hacked, it will be the one you have to try to recover.

Hi Reid,

To login to Minecraft you would need to use your Microsoft account. Where you signing in via Mojang account? There was a migration deadline where you had to migrate your Mojang account over to a Microsoft account. If you haven't done this it is not possible to migrate your account anymore, you can read more here: Account migration last call | Minecraft

If you are stating Microsoft account has been compromised you can follow the steps here: How to recover a hacked or compromised Microsoft account - Microsoft Support

Please let me know if you have any additional questions.

I appreciate the response.

I understand that the hacking incident happened pre-migration era however I'm afraid you will need to know the Microsoft account that was hacked and associated with your Minecraft account in order to recover your Minecraft.

Once you know the Microsoft email account, try to contact Microsoft Xbox Support again to request for an escalation to recover your account from the hacker.

Best Regards,

Hello again, I don't know what kind of email you used to open your Minecraft account, if you used an email with a Microsoft domain you can try to retrieve it using the form, however if it wasn't, I believe that Mojang support informed you correctly and it will not be possible to recover your account.
