The Address Book Policy Routing agent is a Transport agent that runs on the Mailbox server that controls how recipients are resolved in your organization. When the ABP Routing agent is installed and configured, users that are assigned to different GALs appear as external recipients in that they can’t view external recipients’ contact cards.

For additional management tasks related to ABPs, see Address Book Policy Procedures.
