We've recently started rolling out Salesforce to external locations, but for two of those, we're seeing some strange issues with the Salesforce Outlook add-in seemingly not being rendered correctly when you're on the internal network, if you switch over to the Guest network, which goes over the same internet breakout as the internal network, then it works. Also running Fiddler to debug it makes it work on the Internal network. So far I've tried packet tracing, running process monitor but neither has given me a definitive pointer to where the problem is. Also tested with different DNS, resetting the local network on the PC's, created new firewall policies with all traffic allowed, even though the same policies work at headoffice.
With Fiddler making it work, it points to it being some interception or proxy with the local computer, but there's no proxy configured for those networks.
