As the Exchange 2007 and 2010 technologies are markedly different, you can only manage Exchange 2007 servers from the Exchange 2007 Exchange Management Console (EMC) and Exchange 2010 servers from the Exchange 2010 EMC. Fortunately you can install both the Exchange 2007 and Exchange 2010 Management tools on the same machine.
This should only be performed on a workstation, as installing conflicting management tools on an Exchange server can cause issues. This guide has been tested on Windows XP and Windows 7 workstations.
You will need install disks for Exchange 2007 and Service Pack 2 for Exchange 2010 in order to complete this successfully. The process will run faster if you copy the contents of the install disks to a local folder such as C:\Temp\. The instructions below assume you have copied the Exchange 2007 setup files to C:\Temp\Exchange 2007\ and the Exchange 2010 Service Pack files to C:\Temp\Exchange 2010\.
The first step is to install the Exchange 2007 Management Tools.
1. Run C:\Temp\Exchange 2007\Setup.exe as Administrator.
2. Accept the license agreement > Next > Next.
3. Custom Exchange Server Installation > Next.
4. Management Tools > Next > Install > Finis
Once this is completed you can move on to install the Exchange 2010 Management Tools.
1. Run C:\Temp\Exchange 2010\SP2\Setup.exe as Administrator.
2. Select Choose Exchange language option then Install only languages from the DVD.
3. Hit Step 4: Install Microsoft Exchange
4. Wait for the files to copy and then Next > Accept the terms > Next > Next > Custom >
5. Select Management Tools > Next > Install.
6. Wait for software to install then hit Finish
If for any reason you update the service pack on the servers, you will need to upgrade your client machine too.
