Manage connections from Windows 10 operating system components to Microsoft services using Microsoft Intune MDM Server

Applies to

  • Windows 10 Enterprise 1903 version and newer

This article describes the network connections that Windows 10 components make to Microsoft and the Mobile Device Management/Configuration Service Provider (MDM/CSP) and custom Open Mobile Alliance Uniform Resource Identifier (OMA URI) policies available to IT Professionals using Microsoft Intune to help manage the data shared with Microsoft. If you want to minimize connections from Windows to Microsoft services, or configure privacy settings, there are a number of settings for consideration. For example, you can configure diagnostic data to the lowest level for your edition of Windows and evaluate other connections Windows makes to Microsoft services you want to turn off using the instructions in this article. While it is possible to minimize network connections to Microsoft, there are many reasons why these communications are enabled by default, such as updating malware definitions and maintaining current certificate revocation lists. This data helps us deliver a secure, reliable, and up-to-date experience.


  • The Allowed Traffic endpoints for an MDM configuration are here: Allowed Traffic
    • CRL (Certificate Revocation List) and OCSP (Online Certificate Status Protocol) network traffic cannot be disabled and will still show up in network traces. CRL and OCSP checks are made to the issuing certificate authorities. Microsoft is one of these authorities. There are many others such as DigiCert, Thawte, Google, Symantec, and VeriSign.
    • There is some traffic which is specifically required for the Microsoft Intune based management of Windows 10 devices. This traffic includes Windows Notifications Service (WNS), Automatic Root Certificates Update (ARCU), and some Windows Update related traffic. The aforementioned traffic comprises the Allowed Traffic for Microsoft Intune MDM Server to manage Windows 10 devices.
  • For security reasons, it is important to take care in deciding which settings to configure as some of them may result in a less secure device. Examples of settings that can lead to a less secure device configuration include: disabling Windows Update, disabling Automatic Root Certificates Update, and disabling Windows Defender. Accordingly, we do not recommend disabling any of these features.
  • To ensure CSPs take priority over Group Policies in case of conflicts, use the ControlPolicyConflict policy.
  • The Get Help and Give us Feedback links in Windows may no longer work after applying some or all of the MDM/CSP settings.
