Presumably the email account that's now stopped working received the message from TalkTalk advising "Our records show that you are still accessing your email using unencrypted email settings, because of this, from 17th February you will no longer be able to receive or send emails via this email app or software"?
Have you determined the reason for one or another device to still be using insecure settings? And importantly has that been corrected?
That mailbox will not be able to authenticate a connection until TalkTalk Support restore IMAP/POP3 access.
