We are facing issues with conditional tag/comments for outlook like- (<!--[if gte mso 9]> Code <![endif]-->) which are no more working on outlook. We have checked it on Outlook-2016 and Outlook-2013. Please let us know if anyone facing same issue or there has been some update made for the syntax.
Just to specify we have checked almost all the conditions like (<!--[if gte mso 12]><![endif]--> or <!--[if mso]><![endif]--> or <!--[if gt mso 9]><![endif]--> etc.)
