When you modify a public folder or its contents, the database that contains the replica of the public folder that was changed sends a descriptive e-mail message to the other public folder databases that host a replica of the public folder. To reduce traffic on your network, Exchange includes information about multiple changes in one e-mail message. The amount of information included in these messages depends on the size limit you set for replication messages. If any message exceeds the specified size limit, that message is sent as a separate replication message.
