Microsoft Warns Stop using PowerShell Scripts for Intune Endpoint IPs and FQDNs

Microsoft Warns Stop using PowerShell Scripts for Intune Endpoint IPs and FQDNs. Many IT admins use PowerShell scripts to get Microsoft Intune IP addresses and FQDNs so they can set up firewalls and proxies. These scripts usually came from the Office 365 Endpoint service and made network setup easier.

But recently, Microsoft made changes that make these scripts unreliable. IP Addresses (IPs) are numerical addresses assigned to servers in Microsoft’s network. Devices use these to communicate with Intune. FQDNs are human readable names like endpoint.microsoft.com, that point to those servers.

If IT teams keep using PowerShell scripts to get Intune IP addresses and FQDNs, devices may stop connecting properly to Intune. This can prevent them from receiving updates, apps, and security policies, which can cause disruptions for employees and slow down work.

Using outdated IPs and FQDNs can also lead to wrong firewall or proxy settings. IT admins may spend extra time fixing connection problems, and devices might miss important updates, creating security risks for the organization.

Microsoft has updated their documentation with a critical warning that the old PowerShell scripts no longer return accurate data for Intune endpoints. The IP addresses and FQDNs provided by these scripts may be outdated, incomplete, or even incorrect.

  • Continuing to use these old scripts or endpoint lists can cause problems for modern Intune deployments:
    • Devices may fail to connect to Intune services.
    • Updates and apps may not reach the devices.
    • Remote management tasks could stop working.
    • Firewall and proxy rules may be applied incorrectly.

Use Official Intune Service Endpoints Guidance

Instead of using old PowerShell scripts, Microsoft recommends using the official Intune service endpoints guidance. Always check the latest documentation or endpoint URLs provided by Microsoft and update your network configurations.

Warning Message from MS – The previously available PowerShell scripts for retrieving Microsoft Intune endpoint IP addresses and FQDNs no longer return accurate data from the Office 365 Endpoint service. Instead, use the consolidated list provided in the MS article. Using the original scripts or endpoint lists from the Office 365 Endpoint service is insufficient and may lead to incorrect configurations.
