To ask directly the question that Dmitry's response implies, why would you
use a web application to extract data from a local Outlook user's folders?

At the moment, I need a stopgap solution and I'm most familiar with asp.net
in a web application. Ultimately (as in within the next 4-5 weeks), I plan on
moving it to a vba "macro" - which I have to figure out first since I'm
barely familiar with the Office programming environment. I recognize the
risks, doing what I can to minimize them. Just need to buy some time to
finish off two other applications first. Does this help?
