ipad2 stoped reciving email but i can go to att and see ny new email

ALso are you on a different wifi? For example, I was on public wifi once (AT&T as a matter of fact) and the mail all refused to access my yahoo mail boxes, but I could access them via web mail.

So if you're in a temporary situation - like a different wifi source - just hold tight and access it via web mail. THere's probably a security protocol that isnt' right and it won't work. But once you get it home or on a different network the problem may resolve itself.

WOrst case scenario, say you're on your normal wifi network and it won't work, try deleting and reentering your e-mail account. I've had to do that with Hotmail.
