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.
If the account has been unlocked but you are still unable to recover your account, you will need to try the Account Recovery Form: https://account.live.com/acsr
Detailed steps on how to use the Account Recovery Form can be found here: https://support.microsoft.com/office/b19c02d1-a782-dee6-93c3-dc8113b20c42
Microsoft takes account security very seriously, that's why Account Recovery is an automated process with no human influence. If you don't have the correct information, you may not be able to get through account verification using the Recovery Form.
The Account Recovery Form requires adequate information to prove that you are the owner of the account. The Account Recovery Process can be a time-consuming process, but providing as much info as possible from the start of the process will increase the possibility of being verified by the automated process. You'll need to keep trying until you're verified by Microsoft.
Remember to use a familiar device from which you've frequently accessed your Microsoft account, as well as a familiar location. Microsoft will review your responses and respond within 24 hours. If you are verified, instructions on how to log back into your account will be sent to you, and if you are not verified, you will need to submit the Account Recovery form again. You can do this up to 2 times every 24 hours.
It's important to note that Microsoft Support will not be able to grant you access to your account, you will be sent back to the Account Recovery pages that have been linked above.
If your Microsoft account recovery request was not granted or was unsuccessful, please click the attached link for more information: https://support.microsoft.com/office/dc56c3e3-dff0-4ed5-8edb-60290eea6b53
Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.
Best regards,
