Basic icons don't show up properly in Search results
Icons like ZIP or even MSG don't show up properly in Search Results. Could you please add them to the result templates ?
Thanks for your feedback! Are you seeing this in SharePoint Online or an on-premises SharePoint Server version?

To Microsoft: The issue is with the maptocion api (_api/web/maptoicon) that returns incorrect image url.
For zip file it returns _layouts/15/images/lg_iczip.gif. The image does not exists. Instead it should return _layouts/15/images/lg_iczip.png
For msg file it returns _layouts/15/images/lg_icmsg.png that does not exists. Instead it should return _layouts/15/images/lg_icmsg.gif (However, the issue here is that you should provide the png file...)
