Unlink Xbox Live account from Microsoft account?

Hello Brad,

Thank you for the answer.

I understand that unfortunately it's impossible. However is there a way to unlink or delete the Xbox Live Account linked to the B (target) Microsoft Account and then link the A Xbox Live Account? Or the other way around - unlink Xbox Live Account from the
A Microsoft Account (would the achievements be stored locally then?) and then link it to the B Microsoft Account?

unfortunately email accounts with Microsoft domains (Hotmail, Outlook, Live, etc) can't be unlinked from Xbox profiles

But there's no way to unlink my XBOX account from a Microsoft account without creating a new Microsoft account?

I had the same issue. Had to go to my EA Account and Unlink my Xbox Live account.

After Unlinking, follow the steps to install an EA Play game from the Xbox app. EA Desktop will ask to re-link your Microsoft account.

After doing that it all works fine. Hope this helped.

You can't, only deletes if you delete your Microsoft account
