Hey there! Nice to meet you!
Based on your description, please try resetting your password using different browsers, network services, and devices to see if it works.
If it doesn't work, kindly follow the guide to unblock your account through this link:
If the issue persists, I highly recommend you submit a reinstatement form as a last resort:
https://www.microsoft.com/concern/AccountReinstatement?SilentAuth=1&wa=wsignin1.0
(This is not an account recovery webform/ACSR)
You may receive the results via email within 48 - 72 hours.
If you haven't received a response to the reinstatement request you have submitted after 72 hours, please check your email inbox, junk, and spam folders in case you receive it there.
Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.
Best regards,
Darhyl
