You have a Microsoft 365 E5 subscription and 25 Apple iPads. You plan to enroll the iPads in Microsoft Intune using the Apple Configurator enrollment method. What should you do first?

To enroll Apple devices like iPads into Microsoft Intune, an Apple MDM Push Certificate is a fundamental prerequisite. This certificate establishes a secure connection between Intune and Apple's Push Notification Service (APNs), enabling Intune to manage and send commands to the devices. Without it, Intune cannot communicate with the iPads for enrollment or management tasks. Adding your user account as a device enrollment manager (DEM) is not the first step; it's a role assignment that might be needed later for specific enrollment scenarios but doesn't enable the core communication. Modifying enrollment restrictions might be necessary for specific policies but doesn't precede the MDM push certificate. Uploading device identifiers is part of the Apple Configurator enrollment process itself, but only after the push certificate is in place.
