If you use Microsoft Intune (aka Microsoft Endpoint Configuration Manger) and are filtering Internet access from your corporate network, you need to update your firewall filtering configuration to update the allowed IP addresses for Microsoft Intune.
Microsoft has updated the network endpoints used by Intune due to the added Azure services (Azure Scale Units).
The below IP ranges need to be removed from your rule:
- 13.75.39.208/28
- 104.214.164.192/27
- 20.189.105.0/24
The below IP ranges need to be added to your rule:
- 20.204.193.12/30
- 20.204.193.10/31
- 20.192.174.216/29
- 20.192.159.40/29
