I am building an email with a background image that doesn't scale up well on the Outlook 2013 120 DPI email client. I am able to target Outlook 2013 and Outlook 2013 120 DPI by using <!--[if mso 15]> and pass in a different background image that scales well. However, it would be great if I could target Outlook 2013 120 DPI exclusively and use the original background image in Outlook 2013. Does anyone know how to target only Outlook 2013 120 DPI? Thanks in advance for your help!
