I have been successfully using Outlook 2007 on Windows 10 to send emails from a ***@tiscali.co.uk using the Outgoing server tiscali.co.uk.
About four days ago this stopped working and I now recieve the following error: "Task '***@tiscali.co.uk - Sending reported error (0x800CCC6F) : 'Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to recieve this message, contact your server administrator or ISP. The server responded:554 cm 11gb 1 smtp.talktalk.net ESMTP server not available.
Does anyone know what this error means and how I can fix the problem.
Thanks
Graham
