The Outlook Express is not required but if if it's installed and configured, CDO 2000 can use its configuration.
What kind of authentication SMTP server required and what did you specify?
What properties did you set for the class?

>I'm wondering if the basic auth and the SMTPUsesSSL settings are the issue. Strangly, moving away from a thirdparty email add-on that worked without having to specify an email account name (just a password) somne are reporting a "User name/password is required for basic authentication" message using the CDO method. Any ideas?
