CSS/HTML Rendering for Outlook 7

Oh lovely! You know the HTML email you tested on Outlook and Outlook Express? It's gonna render all different on the new version of Outlook, which is version 7. Check the MSDN note about this big change in the rendering engine (it used to be IE, now it's Word?). Also of interest: a Windoze-only validator plug-in for use in Dreamweaver or in the new MS Expression Web when coding for the MS Word xhtml/css parser....

Update: Bill Burns sends this exhaustive look at what the new-old rendering engine in Outlook 7 can and cannot do with display markup in email.
