The RPC over HTTP protocol allows your Outlook to connect to your Exchange Servers using HTTP/HTTPS when you are away from your office or network. This solves Outlook/Exchange connection problem for remote/roaming corporate users located behind restrictive firewalls/ports.
The information required for the configuration are:
i)Exchange Server FQDN*- This is the name of your front-end exchange server+domain name. So if your server name is Server and your local domain is domain.local. Its FQDN will be server.domain.local
ii)External FQDN/URL - This is the address you use to connect to your server or Outlook Web Access from outside your network i.e exchange.domain.com
iii)Username
iv)Password
* FQDN stands for Fully Qualified Domain Name
