I am trying to do something which I'm not sure is possible. I have an Excel sheet loaded up to our Office 365 SharePoint. The idea is to share that excel file in a folder where certain users CAN edit the file but CAN'T download a personal copy of the excel file. This seems relatively simple, but apparently isn't. Is it possible to have an edit permission which prevents downloading the file? If so....how? OR...is there another way to implement what I'm trying to achieve?
