How do I apply or remove the "read-only" setting?
If the access control for a folder or other container item (such as a note, discussion topic, or any other webCafé item that can hold other items or comments) is set to "read-only," no one can create or edit any items at that specific folder level. To inspect or change the "read-only" access control setting: In some cases there will be more than one "Read only" checkbox to clear, particularly if you are trying to delete or move a folder that contains other items. This Help & FAQs article offers a procedure for iteratively removing "Read only" settings so that a high-level or mass deletion can take place.
