Need to restrict Saving & Printing a spreadsheet

Hi everyone,

While my request may seem repetitive, I have a certain need that I hope some of the experts here can help me with.

I need to restrict printing & saving functionality on a excel spreadsheet that is shared with a large group of people.

I was also hoping for the restricting save part, to do an AD lookup to see if they are a member of group "X", if they are then allow the save, if they are not then deny the save.

Any help provided is greatly appreciated.

Thanks,
