TalkTalk Technical Advice, Hope I Can Help
Hi, I work for talktalk, as a broadband consultant and have just come across this post whilst visiting my dad(BRUMAS).
Firstly the username should be your phone email@example.com(lowercase) with your password the(one that was sent/or you have since changed it to)
Secondly you would need to have set up the email using either the talktalk cd, or click here
Once this is done the mail settings should read as follows
Incoming Mailer Server: mail.talktalk.net
SMTP Server: smtp.talktalk.net
Both should be under POP3, when using outlook express/outlook make sure that talktalk/talktalkbroadband is the default connection(under properties in the email client program).
Also make sure "log on using secure password authentication is not ticked" in the properties box.
I hope this helps, Im down visiting for a couple of days, so any more questions i`ll try to help.
