Pardon my ignorance, but I've looked everywhere for Exchange '101'. Everywhere I look starts off with upgrading and existing situations...
I have a small office (10 ppl) that currently just has an application server. I would like to implement a domain controller and also have exchange server setup.
Do I need both a front-end (in the DMZ) exchange server and a back-end exchange server? I'm assuming it doesn't make sense (security-wise) to have exchange on the same server as the active directory if it needs to be in the DMZ.
What are the steps to establishing a brand new Exchange server? I have a domain, and I believe that I just need to create an MX record that points to the static IP of my Exchange server, right?
I've tried to do my homework on the web, but I haven't found anything that explains it from the ground up.
Can anyone help? Thanks
