Hybrid Joined PC's not showing in Intune

Hi jansgeorge,

Do you have all the prerequisites achieved to enroll your device hybrid? Have you enrolled any other devices using gpo?

Best way to try is enrolling your device manually from Setting and use your email address. If asks for mdm server name, this means CName is not properly configured and that’s why gpo is not working.

Hope this helps!

A Hybrid Joined Device needs to be enrolled into Intune before it's visible in Intune:
