We have the following folder structure:
Folder A
------------Folder A.1
------------Folder A.2
------------Document A.1
I want UserA to be able to see Folder A.2 but nothing else in that folder. So I share Folder A.2 to UserA and using the link in the resulting email they can see the contents of that folder. However if they browse to the SharePoint site they can't see Folder A to then get to Folder A.2. What have I not done?!
