I’ve been encountering an odd problem with Dorico files… whenever any of our staff sends them as an email attachment, Microsoft Exchange Online protection thinks the files are malware. This is true for any Dorico files from any computer, sent from any mailbox (internal or other external services). Weirdly we get the exact same issue with Musescore, but both sets of files are cleared by literally every other system.
Has anyone else encountered this? Microsoft support seem to not comprehend the concept of a false-positive…
