We use SharePoint Online within the O365 environment. We have several document libraries. Within each library we have 30 folders relating to each of our business units. Each unit is responsible for the permissions of the folders within their folder.
What we've found is that each folder owner has been specifying individual users on the folders rather than using the security groups and assigning the users to the correct groups. As each library has a 50,000 limit on unique permissions, we need to recover the situation before it becomes a problem.
Is there a way we can force inheritance back down through the tree from the top level?
