Dear Jazz,
Thanks for reporting this issue in Microsoft Q&A forum.
I fully stand on your shoes when knowing that you are facing a situation where your long-standing account appears to have been deleted or compromised after a recent hacking incident, and I understand your feeling of urgency to recover it.
Since the account may be completely deleted, or the primary email alias has been removed by the hacker, the automated account recovery form will not work because the system cannot recognize the account in the initial recovery steps.
Please be aware that once a Microsoft account is completely deleted, or the primary alias is removed and replaced by a hacker, there is an extremely small chance to successfully regain access. However, live chat support is the only final step that can confirm the exact status and see if any recovery is possible on their security tools.
Please follow these steps to reach the live support team:
- Visit the Microsoft Support contact page: Contact - Microsoft Support
- In the search bar provided on the page, type "Account Recovery" and press Enter.
- Click the "Get Help" button that appears.
- Scroll down the page until you see and click on the "Contact Support" option.
- When prompted to select your product or service, choose "Other Products."
- For the category, choose "Manage Account Security."
- Find and click "Chat with a support agent in your web browser."
- When prompted, please provide a valid contact email where Microsoft can contact you regarding your case.
- Explain your situation clearly: Be concise but provide all the relevant details.
Your patience and cooperation are highly appreciated. Please feel free to let me know if you have any further updates, thank you.
