Hi Ray
Basically you cannot turn it off.
What you can do though is create a new Excel Template and remove the cut and paste buttons from the toolbar for that template only.
And for the shortcuts Ctrl+X and Ctrl+V you could create blank macros and assign Ctrl+X and Ctrl+V to them. That way if they try the shortcuts they will not work.
Hope this helps.
Good luck.
