SmtpMail Could not access 'CDO.Message' object ONLY with HTML form

[Guest]

Hello,

I've read a lot of threads on this subject, but they typically go back to a problem with the smtp server configuration. In my case, everything works great until I uncomment the one line below. Once I set the BodyFormat to MailFormat.Html then I get:

HttpException (0x80004005): Could not access 'CDO.Message' object

Otherwise, everything works fine and I get my html tags in plain text. I've got it working (in plain text) with my local smtp server (as below) and two ISP's... all throw the same error as soon as I set the format to HTML. The email addresses have, of course, been edited for the post.

Any ideas?
Thanks,
Michael

<CODE>

MailMessage m = new MailMessage();
m.To = "(e-mail address removed)";
m.From = “[email protected]â€;
m.Subject = "testing";
//m.BodyFormat = MailFormat.Html;
m.Body = "this is my test email body.<br><b>this part is in bold</b>";
SmtpMail.SmtpServer = "localhost";
SmtpMail.Send(m);

</CODE>

I just ran into the same issue (same message...same conditions).
Switching to text format allows mail to be sent. I suspect it is a
permission issue. I think the mailer is trying to build at least one
attachment to handle the HTML. I'm still investigating.

By the way, here's the full error:

[COMException (0x80040605): Unknown Error]
