F: First we modify the properties of GAL of the ABP so that only Fabrikam users can access the ABP.
An Address Book Policy consists of a subset of the various address objects that exist in the. The resulting scope of an ABP is equal to that of the GAL contained in the policy, Note: Global address list (GAL) segmentation (also known as GAL segregation) is the process whereby administrators can segment users into specific populations to provide customized views of their organization's GAL. Address book policies (ABPs) allow you to segment users into specific groups to provide customized views of your organization's global address list (GAL). When creating an ABP, you assign a GAL, an offline address book (OAB), a room list, and one or more address lists to the policy. You can then assign the ABP to mailbox users, providing them with access to a customized GAL in Outlook and Outlook Web App. The goal is to provide a simpler mechanism to accomplish GAL segmentation for on-premises organizations that require multiple GALs.
E: If you're using ABPs, and you don't want users in separate virtual organizations to view each other's potentially private information, you can turn on the Address Book Policy Routing agent. The ABP Routing agent is a Transport agent 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.
