Microsoft Intune can be used to send custom notifications to managed iOS/iPadOS and Android devices. These messages appear as standard push notifications from the Company Portal app and from the Microsoft Intune app on a user's device, just as notifications from other applications on the device appear. Intune custom notifications aren't supported by macOS and Windows devices.
As an iOS/iPadOS device, the notification displays within the Company Portal app instead of being pushed out as a push notification if the app is open at the time the notification is received. Until the notification is dismissed, it remains on the screen.
The device must be MDM enrolled.
The device must have the Company Portal app
The Company Portal app must be allowed to send push notifications.
