Automatically save an attachment

[BSimpson]

We use outlook 2000 in our office.
I'd like to find out how to automatically save an attachment (a Word .doc
file) when it comes in with specific conditions (from person X with Y in the
subject line, etc...). Right now, I have the messages that meet the
aforementioned criteria being saved to an outlook folder, but I also want to
automatically save the .doc attachment to a specific folder under "my
documents" for future use.

Ideas??

Thanks!
