XADM: Public Folder Hierarchy Replicates Through Messages

SUMMARY

The Microsoft Exchange Server Public Folder hierarchy, as you can see in the Exchange Server Administrator program, is always replicated to other servers in the organization, even if public folder replication is disabled.

Unlike other directory information, the hierarchy is always replicated through the exchange of messages handled by the message transfer agent (MTA). This is also true when replicating within the same site.
