Scanning ZIP folders for executable's in Office 365

I recently had an issue of  a user opening a zip file that had the Crypto virus. I was able to restore from backup and everything is back. So I went in to harden the rules a little on incoming attachment and I have gotten 365 to not allow normal executable's. The issue that I am having is that it is not scanning incoming zip files so you can get executable material in by zipping it, which is how it got in the first time. What do I need to do to get Exchange Online Protection to scan the incoming zip files?

It does scan in archives, see here for example:

If it's a know virus, it should have been detected, last time I checked they had a financially backed SLA for those so you might as well open a SR.

OK I submitted that file using the above link. If they are scanning I wonder why they did not catch this one. It has been around for a little bit. I will see what they come back with.

Sending it in did prompt an security update roll out from Microsoft, and the ticket helped in setting up more defines rules
