Answer 2

I had the same error code and same message in OOBE when setting up my work machine. Not sure if the root cause is same as yours. I fixed the issue by deleting this device from Company Portal and re-install OS then go through OOBE, the "Preparing your device for mobile management" step still took long time but finally pass.
