Over the last 6 weeks or so, I've had/seen several questions about the junk mail folder icon and didn't understand why they insisted the icon was wrong...  I do now.

“My junk email folder is blocked, how do I unblock it?  Nothing goes into the  folder automatically.  There is a small red circle with a diagonal line thru it on the folder symbol.  Outlook 2007.”

This is the correct icon for the folder and doesn’t mean the junk mail filter is blocked or broken.
