All too frequently TalkTalk make some server side changes that require customers to change settings in their email clients. However the only way we become aware of this is when the email service fails due to now incorrect settings. I know the info can sometimes be found in the Help Hub or Community Forum but so few customers use them or only think to do so after the problem arises. So why cant TT alert customers to these changes in advance? A simple message in the monthly billing email would suffice. Would save customers and your support teams a lot of unnecessary hassle.
