Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow Export Contact to Personal Mode" setting in the "Android Knox Container -> Container Restrictions" rule. 2. Verify the setting is disabled. On the Samsung Knox for Android device: 1. Open the Knox container. 2. Select "Knox Settings". 3. Select "Share data". 4. Verify "Export to Personal Mode - Contact" is disabled and attempt to enable this setting.
