Administrators of a board portal can restrict documents within a folder from users who would normally be able to view these documents. Examples of this could be a conflict of interest or a discussion on remuneration.
Add a folder in Documents and give the folder a relevant name, such as "Restricted documents" or "Conflict of interest".
Click on the subfolder and go to More actions > Folder access permissions.
Untick the users whom should not have access to the selected documents. To confirm changes, click Remove. Users with an empty tick box will now not be able to see the restricted documents.
Add the relevant document(s) to the restricted folder. You can now attach the documents from the restricted folder to the correct agenda item to the meeting book.
