I'm beginning to use Outlook 2003 as a GTD tool. The first thing I did was recognize that I would need a way to manage my projects (where a project is just a grouping of tasks) effectively. On this website, I found a trick to utilize the power of Outlook in managing my projects -- I could treat them as Contacts and create a new Contacts folder for my projects (I also found there a form to make entering new projects much easier). Using the Activities tab on the Projects/Contacts allows me to see all items (mail, contacts, notes, tasks, journals) that have the project attached to it -- this is great for doing weekly/monthly reports on projects!

Of course, the problem with this setup is that you really want to attach the proper Contacts and Categories to each item in Outlook. This is generally not a problem when creating new Tasks, Contacts, or Journals as the fields for entering this are right in front of you. It takes more work, however, to attach them to Notes and Emails as the fields are hidden in an unobvious place. And, in all cases, it's time-consuming to go back through a large folder of items to add the Contact/Category. Doing this, though, is necessary to getting the GTD process working well.

Can anyone point me at something (code, add-in, etc.) that would allow me to set a Contact or Category on all emails in a folder?

(long-winded leadup to a simple question)
