Fix blocking of non-Java archives containing META-INF subdirectory
.MUSX files, created by the Finale music notation application, contain a subdirectory named META-INF. From time to time, the Office 365 Exchange malware filter blocks them, falsely identifying them as .JAR files, which they aren't.

This affects .epub files as well
Hey Microsoft, could you please do something about this? It's a major hassle for teachers and students of music!
Patrick Taylor commented
Ouch. This is still a problem a year later. Like Andrew said, this is devastating to the music community. Please don't filter .musx files.
Andrew Levin commented
PLEASE look into this. The .musx file format is ubiquitous in the music world. Music professors, music students, those in the film industry, etc., etc., use this file, and to be blocked from sending them via email is extremely inconvenient. Yes, I can use Dropbox or other solutions to send files, but most of the time -- for me, at least -- it's so much easier to send via email. Please look into this.

We are also seeing this issue, and even with an extension exception they are still blocked.
