Although I send HTML newsletters for a social club, I've only just had to get ready to sending them (from the web mail server)for my company. I use Outlook 2003 as my email handler - and the test newsletters work in them no problem (as they do in hotmail, gmail, and Thunderbird).BUT in Outlook 2007, in a colleagues PC, although they work fine when opened, the preview window shows the html code, not the render.
Anyway of making the render OK in Outlook 2007 preview?
