Use the Restrictions property page to control whether messages from an organization, a site, or a location can travel through the connector. Usually, address spaces are replicated to all Microsoft Exchange Servers, which allows each Microsoft Exchange Server to be aware of all connectors capable of processing messages of a specific address type. Use the Restrictions property page to prevent a connector from being available to the entire organization or site.
For example, an organization may have a site in Europe and a site in North America with connectors in both sites capable of transmitting messages of the Internet (SMTP) address type. Usually, when the North America server goes down, all SMTP messages are routed through the server in Europe. Using the Restrictions property page, you can prevent messages that originate in North America from using the connector in Europe.
You can use the location restriction to divide one site into multiple locations. For example, if North America and Europe are in the same site, you can divide the site into two geographic locations. This enables messages to be sent only to connectors within the same geographic location even though they are in the same site.
|Organization||Messages of this address type that originated from any server in the organization are sent through this connector.|
|Site||Messages of this address type that originated from servers only in the connector server's site are sent through this connector.|
|Location||Messages of this address type that originated from servers only in the connector server's location are sent through this connector.|
