Change or Revoke Shared Access You can change the role that you assigned and delete access. 1. Right-click the folder that is shared and select Properties. 2. Click the Sharing tab to see who has been given permission to access the folder. 3. Select the name and change the permission levels. To cancel the access, select the name and click Remove. 4. Click OK. The next time the grantee syncs with the Zimbra server, the shared folder information is updated. If you deleted access, the folder is removed when the grantee syncs. If you deleted an external or public share, the grantee cannot access the folder.
