Other Intune-related topics, including unsupported scenarios and platform-specific behaviors
@HM_IT,Thanks for posting in Q&A.
From your description, I know you cannot register device to Intune.
Honestly, I haven't met this issue before. Let's do some check.
1.Please check whether you meet the Intune enrollment requirements follow the link below.
https://learn.microsoft.com/en-us/windows/client-management/mdm-diagnose-enrollment
2.Please check if there is any "Enrollment failures" showing in Intune portal.
3.Please check if there is any error message in “Application and Services Logs –> Microsoft –> Windows –> Provisioning-Diagnostics-Provider –> Admin"
If there is anything update, feel free to let us know.
