Cannot access my old contacts file from the new Talk Talk Mail
Are you a TalkTalk broadband customer? What's the email domain, talktalk.net or another?
When you sign in to TalkTalk Mail here do you see the Address Book link on the TalkTalk Mail header? That's where you should see your Contacts.
Is everything else there apart from the Address Book contacts?
