My company has a office 365 subscription so all our Outlook, OneDrive, Skype etc. infrastructure is hosted for us online. I am trying to restrict our emails to a range of ip addresses (as we have just implemented a vpn), but can't find anywhere in the admin or Security centers, or indeed in the docs that allow you to configure the firewall. This seems such a straight forwards thing that I am sure I've missed something.
Client Access Policies seem to only include docs for self hosted exchange servers etc.
