Check Contents

Review configuration settings to confirm "Allow documents from managed apps in unmanaged apps" is disabled.

This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad.

Note: If an organization has multiple configuration profiles, then the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the iOS management tool, verify "Allow documents from managed apps in unmanaged apps" is unchecked.

Alternatively, verify the text "<key>allowOpenFromManagedToUnmanaged</key><false/>" appears in the configuration profile (.mobileconfig file).

On the iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles" or "Profiles & Device Management" or Profiles" or "Device Management".
4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Opening documents from managed to unmanaged apps not allowed" is listed.

If "Allow documents from managed apps in unmanaged apps" is checked in the iOS management tool, "<key>allowOpenFromManagedToUnmanaged</key><true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Opening documents from managed to unmanaged apps not allowed", this is a finding.
