Q&A: What does Outlook:Mac use to render HTML mail?

I saw this question on Twitter:

Does anyone know what Outlook 2011 for Mac is using to render HTML emails?

Outlook:Mac uses WebKit to render HTML mails.  We also use WebKit to create HTML mail.  For those of you who didn’t like Entourage’s HTML mail, I think you’re going to find Outlook’s WebKit mail more to your liking.
