I read a good article this morning by Jeff Sandquist titled How I Get Things Done... which describes how he uses an outlook addin for organizing his email workflow. It is called the 'Getting Things Done In Outlook' addin.
Using a few simple toolbar buttons, the addin allows you to manage your emails in a timely manner. I haven't tried it out yet but I plan on doing so in the next week. Anybody out there have any experience with it?
