Hi, thank you for reaching out to the Microsoft Q&A forum. I’m happy to help.
Unfortunately, if two-factor authentication (2FA) is enabled, the account recovery form cannot be used.
If two-factor authentication (2FA) is enabled on your account, are you able to access your second verification method? If yes, please try resetting your password.
If you’re unable to verify your identity using your recovery phone number or email address, you can complete the account reinstatement form.

Note: This is different from the account recovery form.
Microsoft Team will review the information provided. If they determine that you are the rightful owner, they will reinstate your account. Please note that they typically respond within 48 to 72 hours. Be sure to check your junk and spam folders for their response.
