Support tip: Upcoming Microsoft Intune network changes
12/18/25 Update - This post has been updated to include a new Azure Front Door (AFD) Connectivity Diagnostics Tool to help validate Intune network connectivity after firewall updates. We know many customers don’t always check their service change messages in the Microsoft 365 admin center or the corresponding Message Center content in the Microsoft Intune admin center, so in this blog post we’re highlighting an important upcoming change to Intune network service endpoints. Starting on or shortly after December 2, 2025, Intune will also use Azure Front Door IP addresses to improve security and simplify firewall management. If your organization uses outbound traffic policies based on IP addresses or service tags, you’ll want to review and update your firewall rules to avoid service disruptions. We’ll keep you updated if the timeline shifts. In the meantime, here’s the service change communication that posted to all Intune customers: MC1147982 - Action Required: Update firewall configurations to include new Intune network endpoints As part of Microsoft’s ongoing Secure Future Initiative (SFI), starting on or shortly after December 2, 2025, the network service endpoints for Microsoft Intune will also use Azure Front Door IP addresses. This improvement supports better alignment with modern security practices and over time will make it easier for organizations using multiple Microsoft products to manage and maintain their firewall configurations. As a result, customers may be required to add these network (firewall) configurations in third-party applications to enable proper function of Intune device and app management. This change will affect customers using a firewall allowlist that allows outbound traffic based on IP addresses or Azure service tags. Do not remove any existing network endpoints required for Microsoft Intune. Additional network endpoints are documented as part of the Azure Front Door and service tags information referenced in the files linked below: Public clouds: Download Azure IP Ranges and Service Tags – Public Cloud from Official Microsoft Download Center Government clouds: Download Azure IP Ranges and Service Tags – US Government Cloud from Official Microsoft Download Center The additional ranges are those listed in the JSON files linked above and can be found by searching for “AzureFrontDoor.MicrosoftSecurity”. How this will affect your organization If you have configured an outbound traffic policy for Intune IP address ranges or Azure service tags for your firewalls, routers, proxy servers, client-based firewalls, VPN or network security groups, you will need to update them to include the new Azure Front Door ranges with the “AzureFrontDoor.MicrosoftSecurity” tag. Intune requires internet access for devices under Intune management, whether for mobile device management or mobile application management. If your outbound traffic policy doesn’t include the new Azure Front Door IP address ranges, users may face login issues, devices might lose connectivity with Intune, and access to apps like the Intune Company Portal or those protected by app protection policies could be disrupted. What you need to do to prepare Ensure that your firewall rules are updated and added to your firewall’s allowlist with the additional IP addresses documented under Azure Front Door by December 2, 2025. Alternatively, you may add the service tag “AzureFrontDoor.MicrosoftSecurity” to your firewall rules to allow outbound traffic on port 443 for the addresses in the tag. If you are not the IT admin who can make this change, notify your networking team. If you are responsible for configuring internet traffic, refer to the following documentation for more details: Azure Front Door Azure service tags Intune network endpoints US government network endpoints for Intune If you have a helpdesk, inform them about this upcoming change. If you need additional assistance, contact Microsoft Intune Support and refer to this Message Center post. Note: The above post went to all customers in our public cloud. Customers in Microsoft Intune for US Government GCC High and DoD received the following post (the only difference is the focus on US government network endpoints): MC1147978 - Action Required: Update firewall configurations to include additional Intune network endpoints Note: The previously available PowerShell scripts for retrieving Microsoft Intune endpoint IP addresses and FQDNs no longer returns accurate data from the Office 365 Endpoint service. Instead, use the consolidated list provided in the Intune endpoints documentation. Using the original scripts or endpoint lists from the Office 365 Endpoint service is insufficient and may lead to incorrect configurations. For network best practices, make sure to check out the blog: Support tip: Aligning network policy with Intune and Zero Trust. New: Azure Front Door Connectivity Diagnostics Tool for Intune To help you validate or troubleshoot the recent Intune network changes, we’ve published a lightweight Azure Front Door (AFD) Connectivity Diagnostics Tool. The script tests DNS resolution, outbound TCP connectivity on ports 80 and 443, and HTTPS reachability to the AFD IP ranges used by Intune, directly from an Intune-managed device. This is useful for environments that rely on IP-based firewall, proxy, or VPN rules. Important: This script only tests Azure Front Door (AFD) endpoints. It does not validate connectivity to non-AFD Intune endpoints, including existing Intune IPs, service FQDNs, or related services such as Windows Notification Service (WNS) or Windows Autopilot.
