Sending EMail Issues
I get the following error when trying to send emails from Outlook:
Sending' reported error (0x800CCC6F) : 'Your outgoing (SMTP) email server has reported an internal error.
If you continue to receive this message, contact your server administrator or Internet service provider (ISP).
