Office 365 mscz qurantine
Some of our students have started to use musescore and are finding that when emailing .mscz files as attachments in office 365, the emails are not sent and are being quarantined.
I looked into this and it seems office 365 is detecting the attachments as jar files.
I've checked with Microsoft and when I tested changing a random file to .mscz, it sent successfully, so it is not the file extension, it's the content of the file.
has anybody experienced this?
