XCON: Interoperability Logs (AP0.LOG)

• Microsoft Exchange Server, versions 5.5, 4.0, 5.0

SUMMARY

Interoperability text logs consist of the binary content of X.400 protocol messages passed between Microsoft Exchange Message Transfer Agents (MTAs) on different Microsoft Exchange Servers and between MTAs and client applications. They are used to log messages sent over internal interfaces (XAPI, ACSI, TSI, and NSI).

MORE INFORMATION

Increasing Diagnostic Logging levels to Medium or higher for both the Interoperability and Interface categories will generate AP*.LOG files in the exchsrvr\MTADATA directory. The current log is always named AP0.LOG. Prior logs are named AP#.LOG with the # increasing with the age of the log. When a log reaches 5 megabytes in size it is renamed and a new log is begun.

NOTE: There is no difference between Medium and Maximum for the Interoperability category. However, in addition to its influence on Interoperability logs, the diagnostics logging level of the Interface category determines which Interface events are written to event logs.

Interoperability logs can be instrumental in tracking down configuration problems on MTAs. However, they are valuable only to those familiar with ASCII translations of X.400 protocol. These logs can grow quite large very quickly and cause performance on the Server to suffer.
