Hey there!
Nice to meet you! I'm Darhyl, an Independent Advisor.
Based on your description, according to the official Microsoft website: https://support.microsoft.com/en-us/account-bil...
"Microsoft accounts are usually locked if the account holder has violated our Microsoft Services Agreement. Here are some common reasons why accounts are locked, though not all account locks occur for these reasons:
Malware, phishing, and other harmful activities
Microsoft forbids the use of our services for:
Malware: Sending intentionally unwanted or harmful code or software.
Phishing: Stealing private information from others by tricking or spoofing them into providing it.
Interfering with, harming, or spoofing Microsoft networks, services, or other systems.
Spam
Spam takes many forms. Don't use Microsoft networks to send, share, or publish unwanted emails, comments, messages, photos, reviews, or any other content.
Tips:
Don't send unsolicited promotional or commercial content.
Don't send content to people you don't know or to many people at the same time.
Don't use programs, scripts, or bots to create Microsoft accounts.
Don't spoof or reuse information across multiple accounts when signing up.
Don't create or use multiple accounts to violate Microsoft policies."
Kindly follow the guide to unblock your account through the same link I provided above: https://support.microsoft.com/account-billing/a...
If the issue persists, I highly recommend you submit a reinstatement form as a last resort:
https://www.microsoft.com/concern/AccountReinst...
(This is not an account recovery webform)
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
