Firewall exceptions – setup uk

During one of my last installations we deployed Microsoft 365 via autopilot. This basically worked very well. Only the office package could not be installed.

In another case, the Office applications were already installed, but could not be updated.

Both customers had one general thing in common. This was the used firewall. In this case we are talking about Sophos Astaro UTM.
I am not saying that this problem can only occur with a Sophos UTM firewalls, but in my example I am using that firewall.

The reason why Office could not be installed is that the firewall requires an exception.
