Managing personal Outlook.com account settings, security, and privacy
Hi,
If you cannot sign in to your account and you are unable to reset your password, your account may be blocked. I suggest using the Sign-in Helper tool to unblock it: https://go.microsoft.com/fwlink/?linkid=2214157
If unsuccessful, you will need to fill out this account recovery form to regain access to your account: https://account.live.com/acsr
Microsoft takes account security seriously, so the recovery process is fully automated to prevent unauthorized access. Complete the form using a device and location you've used before, and make sure to provide an accessible email address.
Microsoft typically reviews recovery requests within 24 hours. If your request is successful, they’ll send instructions to help you recover your account.

You can submit the form up to twice within a 24-hour period, so feel free to include any new details you remember each time until you recover your account.
