Managing personal Outlook.com account settings, security, and privacy
Thank you for the information.
Since you have two-factor authentication (2FA) enabled, do you have the 25-character recovery codes for the 2FA?
If yes, please go to account.microsoft.com > Forgot Password > click "I don't have any of these" on both verification methods > click "Yes" on the 25 recovery code (if you have one) > from here, you will be asked to wait 30 days in order to update your security info and recover your account.
During this time, you will not be able to sign in to sites or services with your account.
However, if you do not have access to all of your verification methods and the 25-recovery codes from your 2FA, I'm afraid it is no longer possible to recover/unblock the account.
Thank you for your understanding.
Best regards,
Darhyl
