MAPI and CDO Installer for Exchange 2007
December 31st, 2008 by Paul Sterley | Filed under Exchange Server, Not in the Exchange Box.This causes many of these applications to fail to install correctly or talk to the server. Some of them are written well enough to check for this problem and tell you about it during the installation. Some of them may fail to mention one or the other, or give you a link to the CDO download but not to the one that includes both MAPI and CDO.
The CDO installer (the one without MAPI) complains that Outlook 2007 is not yet installed.
It is very likely NOT necesary for you to install Outlook 2007 on your exchange server. Instead, download the Exchange MAPI+CDO add-on from Microsoft. The download size is just 2.4MB.
Since Exchange 2007 does not include MAPI (nor does it use MAPI internally), there are no concerns about a MAPI conflict arising from the installation of it on the Exchange server.
