Intune Enrollment Error 0x800705b4


The device platform enrollment restriction policy can used to block the enrollment of personally owned (BYOD) Windows devices. When you encounter this error you should check the policy to confirm if BYOD devices are blocked.

You can follow the below steps to check the device enrollment restriction policy.

  • On the Intune admin center navigate to Devices / Device onboarding / Enrollment
  • Select Device platform restriction
  • Click on Windows restrictions
  • Under Device type restriction, click All users under the default restriction policy. If you have custom policies then click on Policy name.
  • Select Properties and validate the restriction settings configured for the policy.

The solution depends on the organization’s policy.

If your organization allows the enrollment of Windows BYOD devices then edit the platform restriction policy and change the setting to Allow. That will fix the issue and you can enroll personally owned devices to Intune.

If your organization does not allow the enrollment of personally owned Windows 10 and later devices then technically you can’t do anything. However, you can reach out to your IT decision-makers to discuss the possibility of allowing personally owned Windows (BYOD) devices.
