To configure VPIM on the Microsoft Exchange Server 2010:
Open the Exchange Management Console.
Expand Organization Configuration, select Hub Transport, and then in the work pane, click the Send Connectors tab.
In the action pane, click New Send Connector. The New SMTP Send Connector wizard starts.
On the Introduction page, follow these steps:
In the Name field, type a meaningful name for this connector. Specify a name for the Send connector that helps you distinguish this Send connector from other Send connectors in your configuration.
In the Select the intended use for this connector field, select the usage type for the connector. The usage type determines the default permission sets assigned on the connector and grants those permissions to trusted security principals.
Click Next.
On the Address space page, click Add to specify an SMTP address space to which the Send connector sends mail. Enter the fully qualified domain name (FQDN) of the host.
Click Next.
Configure other settings as required.
On the Completion page, review your settings and then click Finish to close the wizard.
