Acquiring and Installing CDO

You can acquire CDO in one of several ways, for example:

• Windows 95/98/NT Workstation: Download Outlook 98.
• Windows NT Server: Download Exchange 5.5.

When you install Outlook 98, you should have cdo.dll, cdohtml.dll, and mapi32.dll installed onto your system. When you install Exchange 5.5, you must take special steps in order to install these libraries. Choose Custom Setup. From this setup, select IIS/Active Server/Active Server Pages Option. This setup process causes the earlier DLLs to be installed on your system.

You may for some reason get stuck manually installing the CDO library. You can easily do this with the following statement:

regsvr32 cdo.dll.

Type this command from a DOS prompt. The regsvr32 is a utility that invokes self-registration routines embedded within an in-process COM object such as cdo.dll.

CDO 1.21 was previously available for download in a redistributable format. However, the redistributable version of CDO is no longer available. CDO must be installed by another product, such as Microsoft Outlook or Microsoft Exchange.

Outlook 2000 installation does not include CDO component by default, CDO component has to be chosen during the installation.
