Error: smtp does not support SSL-secured connections (Outlook 2003

[Calvin]

My PC: XP Pro
I am using Outlook 2003

After I started using email through SMTP authentication with
port 587, the email cannot send out. The message just sits in the outbox for
a long time and then fails with an error.

The error says "Your outgoing (SMTP) server does not support SSL-secured
connections" with the error code
0x800CCC7D. The weirdest thing is that when I send a test message it sends
with no problem.

I have tried this account on another computer with the same setting.
Everything works fine.

The e-mail provider does not support SSL connections. In the e-mail
account that you defined within Outlook, advanced settings, do NOT
enable SSL connections.

Sorry I need to clarify. The server does provide SMTP authentication using
port 587. I am the server administrator myself.

The strange part is that it only does not work on this particular PC.

Thanks!

All that "SMTP authentication" means is that separate login credentials
are sent to the SMTP server rather than relying on reusing the login
credentials that were used for the prior POP session. Nothing to do
with SSL.

Is SSL enabled in the e-mail account defined in Outlook?
Is SSL supported by your SMTP mail server?
