Setting up a spam filtering rule in Outlook
(This walk through was done in Office Outlook 2003 running Windows XP)

1. Open Outlook
   
2. Select the Tools menu
   
3. Select 'Rules and Alerts'.  this will bring up a window titled 'Rules and Alerts'
   
   
4. Click on the 'New Rule...' button
   
   
   This will open the 'Rules Wizard' window.
   
   
5. In Step 1 of the wizard, select 'Move messages with specific words in the subject to a folder'.
   
   
6. In step 2 of the wizard, click the blue link that says, 'specific words'
   
   This will open the 'Search Text' window.
   
7. In the Search Text window's first field, type '-SPAM-' (Capitalize the letters and be sure to put a hyphen on either side of the word).  It should look like the image below:
   
   
8. Click the 'Add' button in the 'Search Text' window.
   
9. Click the 'OK' button in the 'Search Text' window.
   
10. Return to step 2 in the 'Rules Wizard' window and click 'specified'.
    
    
11. This will open the '' window.  In this window, select the folder you'd like the spam placed in.  (If you'd like the spam to be deleted when it comes in, you can select the 'Deleted Items' folder.)
    
    After selecting the folder you want it to go into, click 'OK'.
    
12. Looking again at the 'Rules Wizard' window, click 'Next >' four times until your screen looks like the one below:
    
    
13. Rename your rule by typing something such as 'Spam Filter' into the first field under 'Step 1:Specify a name for this rule'.
    
14. Click 'Finish'.  This will return you to the 'Rules and Alerts' window where you can now click the 'Apply' button.
    

Done!  Now all email that has been marked as '-SPAM-' will be deleted or filtered to a folder of your choice when you receive it.
