Keep junk out
Windows Live uses SmartScreen technology, which is designed to catch spam before it reaches your inbox. Despite this, every once in a while, spam messages appear in your inbox, or legitimate messages are sent to your junk email folder. With Hotmail, you can decide what you want and don’t want to see.
Is it safe?
If you see a message in your inbox that you think is spam, select the check box next to the message, and then click Junk on the menu.
My friend's been hacked!
Getting spam from friends or family? Help defeat hackers by letting us know something's wrong.
Select the check box next to the spam message, click Mark as on the menu, and then click My friend's been hacked! We'll look for other evidence of hacking and if we find it, we'll help your friend get their account back.
Wait, that's not junk
If you see a message in your junk email folder that isn't spam, click the check box next to the message, and then click Not junk on the menu. Or, move the message out of the junk email folder.
Decide what you want or don't want to see.
