Azure AD registered devices not in MDM intune

Question

Hi I have a question regarding Azure AD registered devices not being shown in Intune

1) the user scope is set to all
2) The only device that is listed under MDM Intune and is Azure AD registered is a virtual machine which is quite odd.

@Anzy21 , For your issue, I would like to confirm if you means when we do Azure AD register, and the user scope is set to all. the device did not enroll into Intune automatically? If there's any misunderstanding, feel free to let us know.

Firstly, we need to confirm which user scope we set for all? did we set the "MDM user scope" as All and "MAM user scope" as None. If not, change to it.

I notice there's only one virtual machine can enroll into Intune MDM. What are the other not working devices? Are these devices with a supported OS version?

Meanwhile, we can go to Event Viewer, checking the log under Applications and Services Logs/Microsoft/Windows/DeviceManagement-Enterprise-Diagnostics-Provider/Admin :to see if there's any error with the enrollment. Here is a link to troubleshoot windows device enrollment in intune for the reference:

Please check the above information and if there's any update, feel free to let us know.

Answer 2

First, these answers assume Windows is the target OS.

Is this a BYOD scenario? AAD registration of Windows endpoints is generally meant only for BYOD scenarios. Anything else and you should strongly consider either hybrid Azure AD join or [full] Azure AD join.

Have you enabled auto-enrollment (see https://learn.microsoft.com/en-us/mem/intune/enrollment/quickstart-setup-auto-enrollment)?

Are your users licensed for Azure AD P1 (or above)?
