MS Word's HTML rendering engine used in Outlook 2007

Why on earth would MS not take advantage to all the improvements made in the IE7 engine with standards compliance and use Word's rendering engine? Just wait until users start complaining about newsletters and other HTML emails not looking right in the new Outlook.

Here's another fine mess you've gotten us into. Thanx Microsoft.
