I’am currently working on a project where we want to AzureAD join some Windows 10 devices after we have deployed them with SCCM.

In our test the uninstall of the SCCM client failed – and it resulted in a error code 8018000a when AzureAD joining the device.

Is seems normal until after user sign in to AzureAD for the AzureAD domain join in the Windows OOBE.

The the error “Something went wrong” shows

It is because it is not possible to AzureAD join a device with the SCCM client installed.

Solutions:

Uninstall the SCCM client with this command “c:\windows\ccmsetup\ccmsetup.exe /uninstall”

Then run c:\windows\system32\sysprep\sysprep.exe /oobe

Now it is possible to AzureAD join the device.
