We have MS Exchange 5.5 SP4 installed. I need to setup Outlook Web browser. Now I can install the application on either the Server itself or on a separate machine on the same network/domain. To enable users from the outside world to enable outlook web client do the machines where Outlook Web Access is installed need another network card with an external IP address? As if I was setting up a web server? Because I can not see any other way how people would be able to access their emails from outside the network.
Any help would be appreciated.
