Report of free collaborators last access date
Does anyone know of a way to get a list or a report of the free collaborators and the date of their last access? I have a Workspace containing a lot of worksheets that has been shared to many free collaborator users. I'd like to see if I can do a clean up of the free users who have been shared to the Workspace but no longer access the sheets.
Has anyone done this? I currently have a Business Account that I administer.
