MAPIDBG.INI [Simple MAPI] Section

The entries in this section control debugging features in Simple MAPI, including the long message identifier cache and the thunking layer.

DumpCacheContents = 0|1

If this entry is set to 1, the entire contents of the message identifier cache are dumped to debug trace each time the cache is accessed or modified. If it is 0, the cache is not dumped. The default value is 0 —the cache is not dumped.

MessageIDCacheGrow = number of entries

This entry controls the number of entries by which the cache grows when it is in runaway mode. When it is in circular buffer mode, its size does not change. The default value is 50 entries. This entry is found in EXCHNG.INI (for Win16) or EXCHNG32.INI (for Win32).

MessageIDCacheSize = number of entries

This entry controls the initial size of the cache and the size to which it is reset when returning to circular buffer mode. The default value is 10 entries. This entry is found in EXCHNG.INI (for Win16) or EXCHNG32.INI (for Win32).

TraceEntry = 0|1

If this entry is set to 1, the arguments to each Simple MAPI call are dumped to debug trace. The default value is 0 — calls are not traced.

TraceMessageIDCache = 0|1

If this entry is set to 1, normal operations in the message identifier cache generate debug trace output. If it is 0, only errors generate trace output. The default value is 0 — no traces are generated on normal operations.

TracePacket = 0|1

If this entry is set to 1, debug traces are generated for errors encountered on the send side of the Simple MAPI thunk layer. The default value is 0 — no traces are generated for thunk errors.

TraceServer = 0|1

If this entry is set to 1, debug traces are generated for errors and certain operations on the receive side of the Simple MAPI thunk layer. The default value is 0 — no traces are generated for thunk server errors.

TraceVerbose = 0|1

If this entry is set to 1, debug traces are generated for routine operations in the Simple MAPI thunk layer. The default value is 0 — no traces are generated for routine thunk operations.
