The Mail Flow Settings page only appears when the following conditions are true:

The Exchange 2007 routing topology is based on Active Directory sites and doesn't use routing groups. However, to support coexistence of Exchange 2007 with earlier versions of Exchange Server, a routing group is created during installation and all Exchange 2007 servers are automatically included in that routing group.

To enable mail flow between Exchange 2007 and Exchange 2000 or Exchange 2003, a routing group connector is required between the Exchange 2007 routing group and the routing group in the Exchange 2000 or Exchange 2003 organization.

You can use the Mail Flow Settings page in Exchange Server 2007 Setup to select a bridgehead server in the existing organization that is a member of the Exchange 2000 or Exchange 2003 routing group to which you want to create the routing group connector. Then use the Mail Flow Settings page to complete the following operations:


To display a list of Exchange 2000 or Exchange 2003 servers from the existing organization, click Browse.

Select Exchange Server

To select an Exchange 2000 or Exchange 2003 bridgehead server that is a member of the routing group through which you want to enable mail flow to and from Exchange 2007, click the name of the Exchange 2000 or Exchange 2003 bridgehead server, and then click OK.
