Installing D.L. Manager services on an Exchange 2007 Server.

Applies To:

D.L. Manager 5.0 for Exchange 2000, 2003 and 2007 with Microsoft Exchange 2007.

Conditions / Symptoms

When installing D.L. Manager on an Exchange 2007 server, the Service will fail to start (Logon failure) if the MAPI services are unavailable.

Issue / Cause

This is by design.  Starting with Exchange 2007, neither the Messaging API (MAPI) client libraries nor CDO 1.2.1 are provided as a part of the base product installation. As a result, there is functionality missing that many applications depend on. Microsoft Exchange MAPI and CDO 1.2.1 provide access to these APIs, which, in turn, provide access to the contents of MAPI stores.

Work Around / Fix

To enable MAPI on Exchange 2007 servers, install the "Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1" located at: http://www.microsoft.com/downloads/details.aspx?familyid=e17e7f31-079a-43a9-bff2-0a110307611e&displaylang=en
