In Box Drive, moving folder to a different owner looks like it works (a folder dragged to new Box location in Box Drive/Finder appears in the new location), but it actually fails and an OS notification pops up only briefly. The suggested fix (if the user notices the problem and can find the message about it) is also not ideal -- Box wants you to manually move the folder back yourself, but if you don't see this message right away then you might not remember where you moved it from.

Ideally, this would warn the user about the change in ownership in an obvious way (e.g., with a pop-up that doesn't go away until dismissed), then allow the user to continue and complete the move if desired.
