Collaboration Data Objects, version 1.2.1 v6.5.8211.0 is available to download.
Brief Description
Beginning in Exchange Server 2007 and Outlook 2007, CDO 1.2.1 will no longer be provided as a part of the install of the product. As a result, there is functionality missing that many applications depend upon. CDO 1.2.1 is a package providing access to Outlook-compatible objects through a COM-based API.
Overview
CDO 1.2.1 (Collaboration Data Objects, version 1.2.1) is a package providing access to Outlook-compatible objects through a COM-based API. Using CDO, a program can connect to a MAPI store, and then perform operations against that store, including creating and processing calendar items, and resolving and handling mail recipients. Starting with Exchange Server 2007 and Outlook 2007, Microsoft will distribute CDO 1.2.1 as a Web download, separated from the two products.
