PFCA (Public folder connection agreement)

A connection agreement in the Active Directory Connector (ADC) that is responsible for replicating Public Folder proxy objects between the Exchange 5.5 directory and Active Directory. These objects are necessary for sending e-mails directly to the folder. Each PFCA is hard-coded to be two-way, and will replicate between the site naming context in Exchange 5.5 and the 'Microsoft Exchange System Objects' container in the Active Directory domain. It is normal to create one PFCA for each Exchange 5.5 site in the organization. [Exchange 2000]
