Hey Chris,
Well, I've tried searching for the answer to this for you and have had absolutely no success.
I don't use Outlook though - I have Outlook Express. I had hoped that they were similar enough that I might find something useful, but no go.
I have discovered in my wanderings through Outlook websites today that nearly no one has anything good to say about it, so I wish you luck.
I've used OE for years and really like it, although I know there are large and very vocal groups of people who also think it is pretty stinkaroo.
From what I read on one site today, if you have Outlook you might also have OE. If so, you might give it a try as your email program...?
