The Microsoft Exchange Active Messaging component, formally known as OLE Messaging, is designed to work with Microsoft Internet Information Server 3.0 (IIS 3.0) as a server-side component. While Active Messaging calls can be made from both server- and client-side script, this article focuses on the server-side implementation of Active Messaging.

The Active Messaging component is a server-side component that can be instantiated from within an Active Server Pages (ASP) page, allowing ASP to access the messaging functionality and information stored in Exchange Server. For example, e-mail messages and calendar information can be accessed from ASP.


The Active Messaging components are installed and registered on IIS 3.0 by using the custom setup option Active Server Components available on the Exchange Server 5.0 CD setup program. This will install the Help file, the two object libraries, the shipping Active Server scripts on your IIS/Active Server machine, which can then act as proxy access to an available Microsoft Exchange 5.0 Server.

The following steps describe how to install the Active Messaging Components from the Exchange 5.0 CD:

  1. From the Web server, click Start on the Taskbar and select Run.
  2. Click Browse and select \Setup\I386\Setup.exe from the Exchange 5.0 CD (assuming an Intel based Web server).
  3. Select the "Complete/Custom" setup option and clear all except the "Active Server Components."
  4. Follow the online instructions to complete the setup.
