  • Hi,Installing Exchange 2010 on a domain controller isn’t recommended because of the following issues:
    • Active Directory split permissions won't be supported
    • All Exchange servers in the domain are granted domain administrator rights automatically.
    •  Performance implications
    • Exchange 2010 requires to be installed on a global catalog server. Exchange services may not start correctly when the domain controller is also a global catalog server.
    • System shutdown will take considerably longer if Exchange services aren’t stopped before shutting down or restarting the server.
    • Demoting a domain controller to a member server isn’t supported.
    • Running Exchange Server on a clustered node that is also an Active Directory domain controller isn’t supported.

    Still you can neglect the above issues and can install Exchange there. But Microsoft recommends to install Exchange Server on a member server always
