We’ve added a shared status indicator for folders on OneDrive For Business and OneDrive consumer so that it is easier to identify when others have access to a folder from the in-folder view.
Here, the folder Product Reports is shared.
Clicking on the sharing glyph provides more information about who the folder is shared with and how it is shared in the Manage Access pane. From this view, users can access the Share command to send shareable links to others or the Grant Access command to grant permissions to specific people and manage existing permissions to the folder.
