Ensure "Allow documents from managed sources in unmanaged destinations" is set to "Disabled"
Description

The terms "managed" and "unmanaged" refer to app classifications made through Managed Open In, a feature introduced in iOS 7. Managed Open In provides for data containerization. Institutionally-provisioned apps are designated managed. Apps elected by the end user are designated unmanaged. Profile: Level 1 - Institutionally-Owned Devices.
