Microsoft Exchange Server 2007 setup cannot continue because one or more servers in the existing organization are running Exchange 2000 Server without Service Pack 3 or a later version.

Exchange 2007 setup requires that all existing Exchange 2000 Server computers in the organization be running Exchange 2000 Server Service Pack 3 (SP3).

To resolve this issue, upgrade all existing Exchange 2000 Server computers in the organization to Exchange 2000 Server SP3 or a later version, and then rerun Exchange 2007 setup.

For more information about upgrading Exchange 2000 Server computers to Exchange 2000 Server SP3 or a later version, see "Downloads for Exchange 2000 Server" (https://go.microsoft.com/fwlink/?LinkId=86647).
