Hello, it seems I have the same problem.
I cannot send emails, receiving is OK except for one problem - one message now always appears :-
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.
Subject 'Read: Appeal 2207908 (13/01055/VC) Norfolk Lea'
Server: 'smtp.talktalk.net'
Windows Live Mail Error ID: 0x800CCC0F
Protocol: SMTP
Port: 25
Secure(SSL): No .
This message was on my inbox, but I deleted it days ago.
On sending, I get no message, but the email sticks in the outbox. On doing a send/receive I get a task screen with :
Send 7 message(s) ............. Failed
The count goes up when I attempt to send.
I am having to use the onetel mailzone website to send mail (my alternative access to my email).
I don't know if this is due to a Microsoft update as in the original post, but I do recall a glitch affecting Live mail. I have installed a later version of Live Mail to no effect.
Any clues please?
