  • Folder Owner: The owner has all permissions for the folder (including the possibility to share the folder with other users).
  • Folder contact: The folder contact receives automated messages from the folder such as replication conflict messages, requests from users for additional permissions, and other changes to the folder status.
  • Folder visible: Users can see the folder.
