Hi, thank you for reaching out. I’m happy to help.
Your account has likely been blocked due to reasons such as suspicious login activity, multiple failed login attempts, or access from unverified devices or location. This is typically a security measure to protect your information.
When your account is blocked, Microsoft provides instructions on how to unblock it:
If you no longer have access to any of your verification methods, 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.
