Exchange Server MAPI Client and CDO 1.2.1 May 2013
The Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 May 2013 Update is now available to download.
Overview
The Messaging API is a COM-like API that provides access to the contents of messaging stores. 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 either CDO or MAPI, a program can connect to a MAPI store, and then perform operations against that store. Starting with Exchange 2007, Microsoft will distribute the MAPI client libraries and CDO 1.2.1 as a Web download.
