Controlling Exchange Server 2003 Public Folder Replication
These topics present an overview of how Microsoft Exchange Server 2003 public folder replication works, how you can configure replicas, and how you can tune the replication process. Understanding the basic replication processes will help you to troubleshoot replication issues that are specific to your Exchange Server 2003 topology. (For information about common problems that might arise during public folder replication, see Troubleshooting and Repairing Exchange Server 2003 Store Problems.)
These topics also provide recommendations for configuring public folder replication when you have a mixed-mode topology (a topology that includes servers running Microsoft Exchange Server version 5.5), and describes how to use the Inter-Organization Replication tool (Exscfg.exe; Exssrv.exe) to replicate information between two Exchange organizations.
