Hi Gabriel Alejandro Hoyo Granado,
Welcome to the Microsoft Q&A forum.
I can see that there is already a Q&A Assist answer in the thread. Its general guidance is appropriate for compromised Microsoft accounts, especially the suggestion to use the official account recovery process.
However, based on the details you shared, there is an important limitation to clarify. Since the attacker has changed your email address and security information (recovery email, verification methods, and possibly Windows Hello linkage), the automated recovery options - such as the standard recovery form - will no longer be effective. Once the original security information has been replaced, those automated systems are unable to verify ownership, even if you have strong historical proof.
Please also note that as a user‑to‑user support forum, there is no ability here to manually review accounts, restore access, or override recovery decisions. That level of review can only be done by supported channels.
Because of this, the remaining and most appropriate next step is to contact Microsoft Support via live chat so your account can be reviewed directly by a support agent. Please follow the steps below to start a live chat session with Microsoft Support:
1, Visit the Microsoft Support contact page: Contact - Microsoft Support
2, In the search bar provided on the page, type "Account recovery" and press Enter.
3, Click on the "Get Help" button that appears.
4, Scroll down the page until you see and click on the "Contact Support" option.
5, When prompted to select your product or service, choose "Other Products".
6, For the category, choose "Manage account security".
7, Look for and click on "Chat with a support agent in your web browser".
8, Confirm your personal email when prompted - this is the email Microsoft will use to communicate with you during and after the support session.
9, When connected, clearly explain your situation. Be concise but include all relevant details.
I hope this helps clarify why the automated recovery paths are not working and points you to the correct next step for further assistance.
