How To Recalculate Exchange Address Book Hierarchy


View products that this article applies to.

Summary

After programmatically creating a Microsoft Exchange Recipients container, you must recalculate the address book hierarchy. The Exchange Administrator program uses standard Windows Service Manager calls to send a control code to the directory service. The application programming interface (API) for accessing the Service Control Manager is documented in the Microsoft Developer Network (MSDN) Win32 API documentation. The control code needed by the Exchange Administrator is DS_SERVICE_CONTROL_RECALC_HIERARCHY. The value of this constant is 129.

This article demonstrates how to create a Recipients container and recalculate the address book hierarchy. Failure to recalculate the address book hierarchy will result in the container not being visible in the Exchange Administrator program until the recalculation has occurred. You can force a recalculation to occur by doing a refresh (by pressing F5) in the Exchange Administrator program.

More information

The following Microsoft Visual Basic and Microsoft Visual C++ samples use Active Directory Services Interface (ADSI) to programmatically make a Recipients container in the Exchange Server directory and the Win32 API to send a control to the Exchange directory service requesting a recalculation of the address book hierarchy.
