Managing personal Outlook.com account settings, security, and privacy
Thank you for the information.
Since you do not have 2FA and if you do not have any linked verification methods for a password reset, I'm afraid the only way to recover/unblock the account is through the account recovery web form: https://account.live.com/acsr
You'll need to keep trying until you're verified by Microsoft, and you can do this up to 2 times every 24 hours.
If your Microsoft account recovery request was not granted, please review this link for tips on improving your chances of a successful recovery: https://support.microsoft.com/office/dc56c3e3-dff0-4ed5-8edb-60290eea6b53
Please be advised that Microsoft Support will not be able to grant you access to your account.
Thank you for your understanding.
Best regards,
Darhyl
