HOWTO: Export Directory Information to a File Using BatchExport

• Extended Messaging Application Programming Interface (MAPI), version 1.0
• Exchange Development Kit (EDK), versions 5.0, 5.5

SUMMARY

Exporting mailbox information about mailboxes on the messaging system may be required. You can do this programmatically using BatchExport() and passing a few parameters. This article contains the code that demonstrates how to use BatchExport() to write out the mailbox information for all users to the file Test.csv. The program takes two parameters: server and organization name.

MORE INFORMATION

The following code should be compiled as a console application using these libraries:

• Mapi32.lib



• Dapi.lib

#include <windows.h>
#include <stdio.h>
#include <lmcons.h
#include <dapi.h>

void ReportDAPIEvent(DAPI_EVENT* pDAPIEvent);
