Hi Guys,

I'm currently experiencing difficulties in sending emails via Windows Live Mail (2012 version) on a Widows 7 platform. The email is transferred to my Outbox... but just sits there!!! My internet/mail provider is TalkTalk.

The error message is as follows:

An unknown error has occurred.

Subject 'Mail Test'

Server Error: 554

Server Response: 554 cm4nec smtp.talktalk.net ESMTP server not available

Server: 'smtp.talktalk.net'

Windows Live Mail Error ID: 0x800CCC6F

Protocol: SMTP

Port: 25

Secure(SSL): No

Could anyone please advise/troubleshoot, if at all possible???

Thanks in advance!
