This week I worked with a client to send out email messages with eROI and we were testing them in Outlook 2007. I discovered just how limited the HTML coverage is in Outlook 2007 and then finally found this wonderful reference for all of the limitations.
I was trying to add a table border using images, however this wasn’t supported in Outlook 2007.
We ended up going with a CSS border statement instead which was supported even though it didn’t look as cool as our images which used shading.
