I'm struggling with library/folder permissions and I cant resolve one issue in sharepoint online.
I have a library, everybody can read and the owner can create folders. For each folder, the owner sets a title, breaks inheritance and let some users with contribute permissions.
Users will be able to create/upload/delete files and folder within this folder, but I don't want these users to edit folder name or delete it.
This is impossible to achieve with permissions or permission levels, I wonder if a cant manages this constraint with remote handler or policy. Any suggestion? Has anybody been in this situation before?
