Intune Managed Device duplicates and errors joining Intune

Question

Hello everyone, i think i misconfigured my Microsoft Intune Management: My devices get automatically registered to Intune when joining my domain. The output of dsregcmd /status is then:

Then i need to manually add the device to intune management by adding the primary owner of the device:

The device is now connected to the local domain and to Azure MDM via Intune. After a while i will see the applied policies and settings via the Info Button in the MDM Connection if everything went right:

But mostly i´ll see this error when trying to manually add the device to Intune:

Administrative Events is showing this error: When i take a look at Entra ID i will see these devices:

The first entry comes from the automatic hybrid device join via GPO, the latter ones come from my attempts to manually join the device to Microsoft Intune. After some minutes the device shows up with a generic name:

Which will eventually change to the correct name for the device after "some time". I think i do something wrong in the process of adding devices to my Intune Management. But this specific device is stuck with the above error. What is the correct procedure to add devices to Intune? How do i prevent duplicate entries in Azure AD Devices? Thanks for clarification.

@Simon-Timothy Folaji, Thanks for posting in Q&A.

From your description, I know you encountered problems with Intune Managed Device duplicates and Intune enrollment.

Due to Q&A only support English, please provide the error message with English. And could you please inform us what kind of Intune enrollment you are trying.

As for how to prevent duplicate entries in Azure AD Devices, here is a link can help.

The enrollment might take some time to finish, please wait. And if you want to switch the device's Ownership, you can go to Intune portal > click Devices > All devices > Select one device > Click Properties > Change the Ownership.

Please try above information, if there is any update, feel free to let me know.
