Outlook 2007 - Rules aren't processing correctly

Be sure to check the "stop processing more rules" after entering your Rules Wizard criteria.  If you don't check that box then you'll either get duplicate email messages in your folders, or the rule won't work at all.  This works differently than in Outlook 2003, Outlook Express, or Windows Mail.

You'll see "stop processing more rules" after the clicking Next under "What do you want to do with the message?"
