Yes, I'm having the same problem.
In my case, it happens when the template links to an external image (like a logo on a website) <img src=... />
If I remove the image, Outlook displays the entire template without any formatting, as in...

If I send the same email to a Yahoo! account, the body is completely empty, no matter what I do.
Anyone else have this problem?
