If you have Windows XP and Outlook 2003 this is what you
need to do. (I'm not sure if this will work on other
versions of Windows/Outlook but try it out anyway)
With outlook closed
Go to this folder in your hard drive...
C:\Documents and Settings\(username)\Application
Data\Microsoft\Outlook
Delete the file "Outlook.NK2" or rename it to something
else.
That's it! Next time you open Outlook, you'll see that
you will start to recreate the list. Anytime you want to
clear it just follow the same steps.
The file will be rebuilt when you close Outlook again.
Good luck!
