I'm planning to use Outlook as my tool to implement the GTD system. Unfortunately, I can't install the add-in template, because my company has locked down Outlook to prevent customization. That means I'll have to implement GTD via categories, user-defined fields, etc.

Has anyone had any experience doing this? I could really use some advice. For example, I'd like to track each task by (a) the person or persons to whom I delegated it, (b) the project it pertains to and (c) if it's a task I will perform, the place where I will perform it (e.g., at the computer). If I try to do all of that with categories, then I'm going to wind up with a ton of categories, which will make category selection difficult. But if I don't use categories, then I'm not sure my task information will sync to my Blackberry.

Anyway, I'd really value your advice. Thanks very much.
