The issue you are facing:
When a folder is shared to some group, users of that group can rename or delete the name of the shared folder. The only way to keep it back to the users is to remove the sharing and do it again.
@jotoeri, thank you, groupfolders app is what I’ve been looking for. Though, in my case the app shows strange behaviour: I was not able to create any groupfolder on the site until I created the first one using occ.
Yeah, i also had some similar strange behaviour lately. The first try to create a folder does not work, but if i try a second time for the same folder, then it works… Probably worth to create an issue on Github…
