When you have an Outlook account that is set up to use Secure Sockets Layer (SSL) and you try to send an SMTP e-mail message, you may receive the following error message:
Unknown Error: 0x800CCC7D


This behavior can occur because the outgoing SMTP server does not support secure connections.


If secure connections have worked in the past, it is important that you contact your server administrator or Internet service provider (ISP). There could be a security issue in which someone has redirected your SMTP connection to another server with the intention of gathering cleartext username and password information.
