Outlook 2007 and email newsletters

News about Microsoft’s release of Outlook 2007 next month, and the fact that the new release breaks HTML rendering, is causing lots of comment from anyone involved with email newsletters.

Instead of using Internet Explorer 7 for rendering HTML, Outlook 2007 will use Microsoft Word’s rendering engine, which we all know produces lovely non-standard compliant HTML. Background images will no longer be supported; neither will forms, floats, and clears.

I know I’ll be spending time with clients in the next month re-working their email newsletter templates to get them to display well in Outlook 2007. Microsoft kindly provides an HTML and CSS validation tool to validate your newsletter in Outlook 2007.
