Intune managed devices are receiving MAM policies configured for Unmanaged devices
You have MAM Policies for Managed and Unmanaged Devices, Intune managed devices are receiving MAM policies configured for Unmanaged devices
As a rule, if you didn't configure IntuneMAMUPN for each targeted app on the managed device, App protection policy will apply to all devices whether it's managed or unmanaged.
In the easy words, the target app will not understand whether it's installed on managed device or unmanaged device.
After i deploy a configuration policy towards managed apps to configure the IntuneMAMUPN, issue got resolved.
I have also noticed the profile is not applicable for some of the devices. As confirmed, the pre-request for app configuration policy is:
· For iOS: the app must be downloaded via Company portal (store app or LOB app)
· For android: the app must be downloaded via managed Google play store
Workaround is to deploy the app as required or re-install from company portal app, app configuration policy could be successfully applied.
