Intune Policy causes error: iOS Guided Access Unavailable. Please contact your administrator.
Have you run into the following error when using Intune for Mobile Device Management?
iOS Guided Access Unavailable. Please contact your administrator.
Don’t panic. If you’ve run into this, you may be stymied on what to do as the device is essentially unresponsive. Even hard power resets do not resolve it. A full OS wipe will resolve the issue only until it is re-enrolled.
The cause is simple: a Kiosk mode policy has been deployed to manage an app, which is not installed. Upon booting up, the iOS device attempts to load the application and lock it in the foreground as a Kiosk. When the app is not found, it ends up locking the entire device down in a non-responsive state.
To resolve it, simply remove the Kiosk policy for the device.
This situation only applies if:
- The iOS device is in Supervised Mode
- A Kiosk policy is deployed
- The Kiosk app is not installed
The error may also occur do misconfiguration of other Accessibility related settings, but will typically not fully lock the device down in a non-responsive state. In that case, just navigate to settings > accessibility and turn off guided access.
