Installing Exchange 2007 - basics

Install Windows 2003 Ent x64

Install all Windows Updates - reboot

Install IIS

Check for more Windows Updates - reboot

Run Exchange 2007 setup.exe

MailFlow Settings - <Your old Exchange 2003 Server Name>

Readiness Check - all green? - click install

click yes - reboot - run the setup.exe again to Get Critical Updates for Exchange 2007

- mine found Update Rollup 9 for Exchange Server 2007 Service Pack 1 (KB970162)

install AdminPack

install Resource ToolKit

reboot

Open IIS - change directory security so that it does not require 128-bit encryption

Open Exhcange MMC - Server Config > Client Access - Properties of OWA

- - set the internal and external URLs - make sure that the S from the https has been removed.

- - The internal one I set for http://servername.domain.net/owa

- - The external one I set for http://owa.publicdomain.com/owa

After this part, you're ready to configure your proxy server to handle the incoming traffic to OWA and direct it to your new Exchange Server.
