Yikes..looks like Microsoft is going to effectively cripple HTML-based e-newsletters received by people using Outlook 2007. They are switching the rendering engine from IE6 (lousy) to Microsoft Word (craptacular).

Read it and (more than likely) weep. Considering the penetration of the Outlook bloatware. this is going to impact our mass email capabilities quite severely.
