SUMMARY
This article describes when Microsoft Exchange replication traffic is compressed.



MORE INFORMATION
Directory Replication Traffic:

Inter-site directory replication traffic is compressed by the Microsoft Exchange Directory service (DS) before these messages are submitted to the Microsoft Exchange Message Transfer Agent (MTA). This is done regardless of the underlying message transport.

Intra-site directory replication traffic is not compressed.

Folder Replication Traffic
Only the message body is compressed for both inter and intra-site folder replication. Attachments are not compressed. Transports, such as RAS, may compress lower level data streams.
