When enrolling Windows devices into Microsoft Intune, administrators may encounter the error code 0x800705b4, often during the Device Preparation stage. This error typically occurs when Bring Your Own Device (BYOD) enrollment is blocked by Intune’s platform restriction policies. While the message itself can be frustrating, the underlying cause is straightforward: Intune is preventing personal devices from joining due to policy settings. In this guide, we’ll walk through the root cause of error 0x800705b4 and provide clear steps to resolve it, ensuring a smoother enrollment experience for both IT admins and end users.

Causes of Intune Enrollment Error 0x800705b4
The device platform enrollment restriction policy can be 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.
Step-by-Step to Validate BYOD Enrollment Restrictions
Follow the steps below 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.
As highlighted in the screenshot below, you can see that Windows MDM is blocked for personally owned (BYOD) devices.
Solution
The solution depends on the organization’s policy.
If your organization permits the enrollment of Windows BYOD (Bring Your Own Device) devices, you can resolve this error by editing the platform restriction policy and setting it to Allow. Once updated, personally owned Windows devices can be successfully enrolled in Intune.
If your organization does not allow enrollment of personally owned Windows 10 or later devices, there’s no direct fix available. In that case, the best approach is to engage with your IT decision-makers to discuss whether enabling BYOD enrollment aligns with your organization’s policies and security requirements.
