If your MSN Hotmail account was closed and you don’t know why, it may have been closed because of a violation of the terms of use agreement.
Some examples of terms of use agreement violations include the following:
- Sending unwanted mail or "spam"
- Sending abusive or harassing e-mail
- Participating in phishing or account fraud
Visit the MSN Technical Support website to submit an inquiry about why your account may have been closed.
Also at one time it used to be that if you didn't use the account for a month it would be closed, but I don't know if that still applies.
