Intune - some iPads showing as unknown ownership, most show as corporate

Carol M. Chisholm 26 Reputation points

I have 10 new iPads to register with Intune
All users have EOL Plan 2 and E5 Mobility and Security
They are all in the same groups and we are trying to make al the devices identical.
They are all new devices.

7 have registered fine, 3 show as unknown devices.

We have tried all sorts of things, basically the processes and devices are as far as we can tell are identical but the results inconsistent.

    @Carol M. Chisholm Thanks for posting in our Q&A.

    To clarify this issue, we appreciate your help to collect some information:

    1. Which enrollment method did you use to enroll these iPads?The enrollment methods are listed in the following article:
    2. Please try to sync the device and check if the ownership is changed.
    3. Please check if the management profile exists in Settings > General > Device Management in the iPad.
    4. If possible, please check if there is any enrollment failure message under Troubleshooting + support > select the user you used to enroll iPads > Enrollment failures in intune portal.
    5. Based on my research, corporate device identifiers will affect the ownership. If you import multiple IMEI numbers for a device, uninventoried numbers display Unknown for enrollment status. For more details, please read the following article:
      Please check if there is any corporate identifiers created in intune portal.

    If there is anything update, feel free to let us know.

    We solved this - go more slowly. at the beginning we were testing and documenting the process - wait after each step.
    Then we went faster and it started to fail.
    When we slowed down again it worked again.
