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.
Use of multiple accounts for abuse and other suspicious activity
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.
If it is this one, typically the TOS violations (breaching rules) means that you were reported for behavior activity.
Your account has been suspended for suspicious activity, sending unsolicited emails, or for violating of Microsoft’s Terms of Use agreement, such as hosting photos, video or other content in violation of the Code of Conduct.
