This is my first time doing this so I want to make sure I do things right. Even though this is a site created for testing, it needs to be setup correctly and I want it to be setup like the industry standard.
I registered a domain and it has a static IP address. I setup three servers running Windows Server 2012. One is AD. The second one hosts IIS and a default web page. The third server is running Exchange 2013.
My firewall is setup to forward port 80 to the web server, and port 25 is forwarded to the Exchange 2013 server. Also, port 443 is forwarded to the Exchange Server.
I setup Exchange 2013 and it is working. I can send messages to the outside world. I can also receive messages from the Internet.
For now, I have to enter http://www.hiddencompanyname.com
when I want to get to my default web page. I have to enter https://hiddencompany.com/owa
when I want to get to Outlook Web Access.
When I go to OWA, I am warned about my certificate.
My eventual goal for this test domain is that I want to be able to eventually connect to my Exchange 2013 server with Outlook 2013 using RPC over HTTPS, and I want this domain to be configured like and behave like what people usually do when they setup an IIS server for their web page and a separate server for their Exchange Server.
What is the next thing I need to do so that I can finalize this domain so that I can reach my goal of setting up Outlook with RPC over HTTPS? Is the next step an SSL certificate? Please advise.
