When you create a journal rule in Exchange Server 2007, that change is applied to all Hub Transport servers in your organization
via Active Directory. All Hub Transport servers, and therefore all Journaling agents, read the same configuration from Active Directory. Therefore, this blanket coverage ensures that all journaling agents apply the same journaling configuration.
Keep Active Directory replication times in mind when you create or modify journal rules, as a configuration change needs
to be replicated throughout your organization and read by the Hub Transport servers. This could take several hours.
