We prepared Active Directory in Part 1 of this article. Exchange 2003 is installed on Exch1 and Exch2 and Exchange 2007 will be installed on Exch3. The exchange 2007 installation is going to be “typical” which means only the following three roles will be installed, Mailbox server, Client Access server and Hub Transport server.Before we begin with the installation of Exchange 2007 on Exch3.training.local we need to confirm the following components exist on the server.
- Enable network COM+ access
- Internet Information Services
- World Wide Web Service
- ASP.NET v2.0
From within the Exchange 2007 folder in the command prompt, type setup.com.

Select typical installation and browse to where you want exchange installed, in my case on the G Drive.

I selected Exch2 (Exchange 2003 server) to be used as a server to which Exchange 2007 will connect in order to allow interoperability of mail flow with exchange 2003.

See below how the Organization Prerequisites were completed but the pre requisites for the other roles failed. Exchange 2007 needs an update applied to the .net framework that can be found here.

| 32-bit download – http://go.microsoft.com/fwlink/?linkid=74469 |


Once the update was applied, the prereq’s completed successfully and now onto the installation of the first Exchange 2007 server in the organization.


And that’s it!! Exchange 2007 is installed into the org.
