Automatic registration at join phase

Paulo Silva

I still receiving the error:
User Device Registration Admin log – EventID 304 – adalResponseCode: 0xcaa1000e – recommended step is to check the AD FS claim rules per mentioned above https://docs.microsoft.com/en-us/azure/active-directory/device-management-hybrid-azuread-joined-devices-setup. It is important to have the AD FS claim rules in the described order and if you have multiple verified domains, do not forget remove any existing IssuerID rule that might have been created by Azure AD Connect or other means.

And

User Device Registration Admin log – EventID 204 – Error code: 0x801c03f2 (“The device object by the given id (xxx) is not found.”) – make sure the on-premises computer object is synchronized to Azure AD. Run the Delta Azure AD Connect sync.

Some devices in my environment register as Hybrid and another ones not.
I don't really understand what happens.

I have an ADFS and already followed all the docs from Microsoft.

Any ideia what could be ?
