Well, here's the thing. We have a written policy, but I'm not sure what, if anything, enforces it. We don't want to inadvertently give someone a new way to copy and paste. We could probably use something like Conditional Access to restrict it. Then we would have to test to see if MP's copy and paste was subject to Conditional Access.
What I originally wanted to know was whether MP had any built-in mechanisms to turn off the ability to copy and paste. You may have given me an alternate possibility.
