Hello gpersand,<br />
<br />
Surely you would put an edge transport server in your DMZ that way you only need to expose a small AD subset using ADAM (which is useless to the human eye) and you only have to open a couple of ports to make it work (you set up an Edge subscription on an internal Exchange server to the Edge Transport Server)<br />

If my DMZ edge transport server is compromised, wont that give full access to the lan?

I don't think the Edge is meant to be completely unprotected. &nbsp;This particular definition of DMZ would likely include a firewall on both sides. &nbsp;Also, the Edge server is not meant to be a member of your domain.

I have been researching the best way to implement OWA on a Exchange 2007 server.<br />
I have decided to put a Mail Transport server in my dmz, and then the CAS and Exchange 2007 on another server in my lan.<br />
<br />
What makes this setup secure/safe from attack?<br />
I need to let my boss know what makes me think this setup is safe.
