Dear Mr. Berezniker,

First, thanks very much for you answer and your concern, and, it's a pleasure to "knowing" you.

In fact, I've based my application on your exemple ("cdo2000" class).

The error appears any time the program runs a "field" configuration like:

objCDOConfiguration = CreateObject ("CDO.Configuration")
---> no error so far ...

objCDOConfiguration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "mail.domain.com.br"
---> As soon as the program runs that line, or any other containg Fields configuration, it reports CDO.Configuration.1 Class not registered.

If I despise the error the mail is sent anyway. It's just like the application is (maybe) using a default configuration based on my Outlook or Outlook Express.

Yours,

Dany Wulkan
