Evolution + Exchange + Gmail

I've never used Evolution before although I had a look at it some years ago. Think it was around '01. Anyway, got myself together today and configured it for the company's Exchange server as well as POP against Gmail. I was actually quite suprised to learn that Evolutions Exchange plugin uses the OWA. I always thought it used something IMAP-ish and hence I assumed that I'd have to be connected to the internal network, through VPN etc. Really nice surprise that this wasn't the case. Everything works smooth.
