Some great tips from someone else on organizing high volumes of email in Outlook
If you, like me, use Outlook and need to manage large volumes of email, you may know about such techniques as folders, rules, and the new search folders. Whether you do or do not, I think you'll get great value out of the ideas (and helpful presentation of info) in the following entry. While the post is on a blog about Squeet, a tool and service I've posted on before, the info on Outlook is still substantial and well done.

I'll note that I also shared some similar thoughts in another blog a few years ago.
