Which is ridiculous but strikes me to be done so as to ensure that emails prepared in MS Word render correctly in Outlook?

Of course they could fix MS Word's HTML output and fix Outlook to use MSIE's rendering engine ... but that'd only reduce lockin by allowing Outlook users emails to be read properly in other MUA. Never going to happen.

What is funny is that Word 2013 can be configured to generate pages that even MS's own IE10 won't render properly by default.
