  • Are they all in same Exchange organization?

    Exchange 5.5 and 2007/2010 can NOT put together in coexistence in same Exchange organization. Exchange organization must be running in native mode to install Exchange 2007 which doesn't support to have Exchange 5.5, so you need to remove it before installing Exchange 2007 or 2010.
