A couple months ago I noticed that Microsoft Outlook (more specifically 2007, 2013 and 2013 DPI Scaling) started supporting retina sized background images. I keep testing this each week to see if it was a fluke but I am getting consistant results that indeed MSO is supporting 2x images and not scaling them within the table cell. Has anyone else noticed consistent support for retina sized background images in MSO? Please confirm.
Thank you,
