How does Windows Live protect against spam/junk mail?
Windows Live provides spam and junk mail management as well as a Safety Bar that alerts you to potentially unsafe messages. The HotmailĀ® Team also helps protect you from email scams by posting safety alerts. When you see the Safety Notice shield while using Hotmail, click on it for updated information. NOTE: Some security options apply only when using the web-based Windows Live experience to access your email (e.g not on desktop clients such as Outlook).
