I had an email off TT about linking a TT email to my account but when I click on the button in the email I get the following message?
Can you help?

So long as your TalkTalk email address is not already associated with another MyAccount then simply sign in to your MyAccount and select My Services > Manage TalkTalk Mail and at the bottom Add an existing mailbox...
Follow the instructions and you should see the mailbox added to the My Mailboxes list (subject to what I said at the top of this post).
