Is Microsoft's Outlook Team on Crack?

I’ve been playing with Outlook 2007 for a few weeks now, trying to get over the fact that it falls short of “impressive” in nearly every way. I wasn’t sure why HTML email messages were looking as though they had fallen out of the ugly tree – until I read this Campaign Monitor post that claims Microsoft takes email design back 5 years:

Previously you could send a HTML email in the comfort that the majority of your recipients would have very good CSS support. Other email clients were also catching up. Thunderbird uses the Firefox rendering engine, the new Yahoo! Mail beta has great CSS support. Things were looking good for us CSS based email designers. Unfortunately, that all goes down the toilet now.

What goes in the toilet – HTML email newsletters in general, or Microsoft Outlook? Not sure why people are so surprised about this turn of events; I’ve been telling you that every release of Outlook (beyond the 2000 client) has been craptacular. Then again, maybe Microsoft completely agrees with my “email is dead” argument? The jury is still out on this one.
