Hi All,
I have configured the HAAD joined + Automatic Intune enrollment for our on-premises devices, but whoever login with subdomain's UPN suffix, it won't enroll with Automatic Intune.
For example, let say our Azure AD primary UPN suffix is @abc.com, and if user xyz@abc.com logon to the device, it is working without an issue. the issue is that if user xbt@sd.abc.com logon to their PC, it will registered as a Hybrid AAD joined device, but it won't enroll with Intune.
When I checked the device management logs in event viewer below is the error that I can see.
Device Credential (0x0), Failed (Mobile Device Management (MDM) is not configured.)
further, if I checked the dsregcmd /status, I have identified SSO state showing as NO. please refer the below screenshot.


appreciate the help!
Thanks,
Dilan
