This can be done by Transport rule on Edge server if u have or the Hub transport server.

you can set message that your company doesn't supports .zip files or else u can simply drop this without NDR to others.

The ZIP file method is very old and a decent Exchange integrated anti spam/AV tool should be able to deal with them. The attachment filtering options built in to Exchange are a bit of blunt instrument - they just block everything which is a ZIP file, whereas a tool will actually look at the included files to strip them.

This is something you are going to need third party software to do.
