View Sharing Information dialogue box
Use the View Sharing Information dialogue box to view information about a folder or document another user has shared with you. The dialogue box identifies the name of the shared item, the name of the user who shared it, and the names of the users with whom it has been shared and their permissions.
To access the dialogue box for a specific folder, open the My Folders page, select the Shared by Others option in the left pane, and select the folder whose sharing information you want to view. Select Actions to the right of the folder name and select View Sharing Info from the list that appears.
To access the dialogue box for a specific document, open the folder containing the document as described above, then open the document and select the View Sharing Info link at the top of the document.
