Managing personal Outlook.com account settings, security, and privacy
Hello Pongpon MOOMON,
I understand that the attacker changed the password, recovery email, and Authenticator method, leaving you unable to complete two-step verification.
Please note that this is a user-to-user forum, so contributors cannot access account records, verify ownership, remove two-step verification, or restore the account.
When two-step verification is enabled and none of the registered verification methods are accessible, the standard recovery form cannot bypass that protection. Support agents are also not permitted to send password-reset links or directly change an account’s security information. Purchase receipts and billing details may help document ownership if requested, but they do not guarantee recovery or override the security requirements. See Help with the Microsoft account recovery form.
Since you have already attempted the available recovery process, contact Microsoft Support for account-specific guidance:
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.
The available contact options may vary by region and sign-in status, and the agent must still follow the same account-security restrictions. However, this is the appropriate channel to ask whether any account-specific review option remains available.
I hope you are able to reach the appropriate support team through these steps.
