deleted folder is the best suggestion, drag and drop back into InBox and put up with the advert - I guess. I don't get that with my Yahoo subscriptions, but they are probably not the same kind. eg Tradsong Forum.

BTinternet is not just a pian, but is unworkable.
A friend moved to BT (MotoGP was the only reason) and I struggled with setting up her e-mail in Livemail and Outlook 2007.
The BT guy (Bangalore) was looking at what we had done, sugessted a load of things I had already tried, he watched with the same results. He gave up and it went to a BT person in the UK who failed to get things sorted despite having full control and tried same settings.
Friend is now on WebMail only.

As for BT Sport, I have never known a more unprofessional outfit, live content goes silent as an offscreen interview is conducted, with commentators then commenting on the interview that we didn't hear! As for their website on Catch-Up TV. It shows you all the results unless you size the browser to a ridiculous value and click one obscure button. And then they show a picture of the first two! Always the first 2! Either amateurs or idiots who don't use their own products IMNSHO.
