CA ARCserve Backup uses Microsoft’s Messaging Application Programming Interface (MAPI) and Collaboration Data Objects (CDO) technologies to perform granular e-mail backups and restores.

Microsoft Exchange versions 2007 and 2010 do not include these technologies by default. The Exchange Administrator will need to download the MAPI-CDO package from http://www.microsoft.com/en-us/download/details.aspx?id=1004 and install it on the Exchange servers that you will be protecting.

If the MAPI-CDO package is installed before the CA ARCserve Backup Agent for Exchange is installed, ARCserve will detect the presence of the required binaries and automatically prepare the Exchange server for granular backups and restores during the Agent Installation.

If the MAPI-CDO package is installed after the CA ARCserve Backup Agent for Exchange is installed, please perform the following steps to enable granular backups and restores:

Make sure that no one is using the CA ARCserve Management Console to perform any operations (i.e. browse, backup, restore, etc.) on the Exchange Server.
Login to the Microsoft Exchange Server

Stop the CA ARCserve Universal Agent Service.

Open a command-line window, and go to the CA ARCserve Exchange Agent’s home directory
Under the “DocumentLevel” subdirectory, execute the following command

ExchDocWrapper.exe –regServer
This command verifies the existence of the MAPI-CDO package and registers the Document-Level functionality.

Start the CA ARCserve Universal Agent service

You will now be able to perform document-level backups of your Microsoft Exchange servers.
