No, I am unable to open the document in Word Online.  As I said, this document existed already in the doc library before I created the MCAS file policy.  If I now create a new doc, it works as expected.  Very strange.  

 

I'm going to play around with this some more.  In the meantime, I would recommend opening a Microsoft support case to see if they can advise on this behaviour.
