Thank you for letting me know.
Please know that if a Microsoft account is hacked and the email address is changed, the account is essentially lost and cannot be recovered. In this case, the Account Recovery Form will no longer work.
If you haven’t already, you can try using the Microsoft Self-help tool.
- Visit https://support.microsoft.com/account-billing/how-to-recover-a-hacked-or-compromised-microsoft-account-24ca907d-bcdf-a44b-4656-47f0cd89c245 and click "Start".
- The tool will ask for your email address or phone number, and either show appropriate self-help, or offer the chance to talk to an agent.
- If nothing works, try contacting Microsoft support via live chat.
You can also use the Xbox recovery form here:
- Visit https://support.xbox.com/forms/recover-your-microsoft-account
- For guidance using the form please see "Guidance notes for the Microsoft account recovery form" https://support.microsoft.com/account-billing/guidance-notes-for-the-microsoft-account-recovery-form-4dd8fef1-33d2-4fbe-9352-66127ab9b50e
Let me know if you have any further questions or concerns.
