How can I fix 'MCCloudConfigErrorDomain – 0x80EF (33007)' error on my iPad Air 2?

Hi everyone.

Currently trying to setup some iPad Air 2 (15.8.4) for one of my schools and adding it to our MDM and ASM.

The way that we do this, is by using a MacBook with Apple Configurator 2 on it, wiping the iPad first, connecting it to the Mac, then using AC2 to 'Prepare' it. Our MDM is InTune, so after it appears as a device in MDM, we sync it with InTune and assign it a profile and it usually works fine.

The issue we are having at the moment is that for a couple of the iPads we are currently getting the below error message when trying to 'Prepare' the device in apple school manager:

MCCloudConfigErrorDomain – 0x80EF (33007)

After looking through different forums/discussions, along with the one here, and trying lots of the solutions that seem to work for others, nothing seems to be successful for us.

We have tried making sure it is connected to the WiFi after being reset and then preparing it while still on the setup screen. Making sure the proxy/DNS settings are all configured correctly. Making sure that the exact steps on the Macbook/AC2 work with other iPads, etc.

Any other option to get these working?

Thanks in advance
