The CDO.Message object errors sometimes occur when using the shopping cart or other modules that need to send emails.  The system sends email  via the standard ASP Dot Net email handler, and the email settings in the application have to be set correctly for this to work properly.

The following criteria must be met:

In the Configuration files, web.config, config_yourmachinename, and Common.ascx, the SMTP server setting has to be set to your mail server and the email address should be correct

The mail server must be set-up to accept connections from the server running the mail component,

That mail server has to be set-up to process the mail, or the CDO.Message error will occur.

Once you make sure that the above conditions are met you will no longer have the CDO Message Object Errors.
