• Exchange Server 2010 only runs on Windows Server 2008 and Windows Server 2008
R2. Since Windows Server 2008 also needs some additional software to be installed, and
bearing in mind the improvements in Windows Server 2008 R2, the latter is the better
option.
• Any Active Directory domain containing Exchange objects has to be running in (at the
very least) Windows 2003 domain functional level.
• The Active Directory forest also has to be running in at least Windows 2003 forest
functional level.
• The Schema Master and the Global Catalog Server(s) have to have a minimum level of
Windows Server 2003 R2.
• Exchange Server 2010 cannot be installed in an organization where an Exchange Server
2000 exists.
