At the moment, we have different sites in Sharepoint for every department. However we want to transfer everything to one site for the entire company, and in that site have subfolders for every department instead. However one problem that I encounter with that is that at the moment, each department head are owners of their respective sites. This enables them to control their department site/folder and modify access and permissions for each document.
If we make one site however, and each department has their own subfolder. How can we assign them ownership of their subfolder, but not ownership of the entire site. Because we do not want the department head of IT to be able to go into HR and be able to see everything, or modify access.
