A Search Folder is a very handy folder for quickly viewing email meeting a certain criteria.  By default there are three standard folders within the Search Folder. 


The neat thing about Search folders is they allow you to search mail locally stored (Personal Folders), in your Outlook mail folders or in the case above, mail that has been filtered by the Spam program.

You can create a Search folder where you specify criteria.  For example, by words, date received/sent, by importance, etc.
