Hello, I have Dropbox Enterprise account. My research shows that I can view the history of views for a document or folder. I feel like I found where to do this in the "activity tab" but the people to whom I need to know that they viewed show up as 'external participant' with locations that suggest a VPN. Am I looking in the wrong place? We need to know if someone viewed a document to help us close on a RE transaction. If this feature does not exist is there a way to require confirmation of viewing to those people we share a folder with?
