Hello!
We've had this problem quite long now.
Some times we get support requests, which does have only "(empty)" there, where the message should be.
We have narrowed down the issue and it seems when the message is sent from Office 365 mail and message contains scandic letters such ö or ä (which are common in Finnish language) mail body comes empty.
I attach my example email in this post.
