MAPI CDO Not Installed

When creating a mailbox backup of your local exchange server, you may see this error.

Assuming the backup client is installed on the exchange server and the version of Exchange server is 2007 or above (required for mailbox backup) you will need to install Microsofts MAPI Client and Collaboration Data Object.  Please view and download from here

From Exchange 2013 or above please download the MAPI from this link:

Once installed, you should be able to create your mailbox backup.

You may also need to look at your MAPI profiles to make sure they are correct.  Please refer to this link for more help.
