Has anyone had experience with MSO conditionals not working in Outlook 2014 on Mac? My templates use the <!--[if !mso]><!-->…<!--<![endif]--> conditional to hide mobile-only content from Outlook since it doesn't respect display:none. For some reason my client's Outlook doesn't seem to acknowledge the conditional comments, so it's showing both desktop and mobile content in the tests.

I've spent about an hour on Google and I can't find anything regarding this. Any help would be greatly appreciated!
