Renew Apple MDM Push Certificate for Microsoft Intune Apple Enrollment

When you configure Apple enrollment on Microsoft Endpoint Manger (https://endpoint.microsoft.com), you must have configured Apple MDM Push certificate which is a prerequisites for configuration of Apple enrollment for Microsoft Intune. The certificate expiry is normally 365 days and when its near its expiry date you get notified 30 days and then 10 days before.

If you do not renew the certificate and it gets expired then a new certificate will need to be generated and installed which will require all the apple devices to get re-enrolled. Therefore, its easier to just renew the certificate before expiry date. I will suggest to note down the certificate expiry date and add a reminder in outlook or a powershell script or something which will send an email to the admins that the certificate is about to expire.
