I've got a SharePoint document library with a folder structure as follows:
The library is called Customers. Inside of this library, there are about 150 folders for each of our different customers. Within each customer folder, there are several uniform folders such as CustomerInfo, Contacts, Billing, etc. I want to make it so that the users of the site are able to create new folders directly inside each Customer's top level folder, but not delete any of the uniform folders that we have created. They should not be able to add/delete Customers to the document library, but should be able to have 'full control' once they are below each individual Customer's top level folder.
Is there a way to do this for the entire document library at once, and for all future additions to the library? The permissions need to be unique based on how many folders "deep" you are.
