exchange_emsmdb¶

Name¶

http(8gx) processing plugin for the Wire Format Protocol (Outlook/Exchange RPCs).

Description¶

exchange_emsmdb is a processing plugin for http(8gx) which handles the remote procedure calls for the EMSMDB v1 and AsyncEMSMDB v1 RPC interfaces, as well as OXCROPS as issued by the EcDoRpcExt2 call or the MAPIHTTP EXECUTE call.

EMSMDB is a DCE/RPC interface with just a few RPC calls (6 are still used today). ecDoRpcExt2, a call offered by that interface, takes an opaque byte buffer argument not interprted by DCE/RPC. That byte buffer contains another protocol, “Remote Operation(s) Encoding Protocol” [OXCROPS]. No reason for this wrapping is given in the OXCRPC spec. MAPIHTTP runs OXCROPS directly without the extra EMSMDB framing.

OXCROPS consists of 130 calls that make up the mailbox protocol.
