How to Make Microsoft Intune Client Work Behind Corporate Firewall Proxy


It won’t be much easy to test InTune client functionality on office machines which are connected to cooperate network. Mainly all the communications are through 80 and 443 (Http and Https) ports.


Microsoft’s blog post suggests to configure or alter firewall and proxy settings to allow Intune server to communicate with the clients. In case, if you’re doing a PoC for Intune, it won’t much easy to get the cooperate firewall and proxy settings changed. The catch is that if your test workstation is behind a proxy server which won’t allow system accounts rather than domain user accounts to access internet site then you won’t be able to test Intune client.

Intune team done a wonderful job to cover all firewall and proxy requirements for Intune client management in one post. More details HERE !!
