I am using windows 7 and in addition to windows 7 yahoo mail i am using windows live email as an alternate. I tried to configure it but keep getting error messages regarding sending out email 800 ccc0f
I had the same error, I tried everything I read everywhere, almost to the point of reinstalling windows and I thought
I might just give my ISP a call and tell them of my error, they remote my computer had a look. they did a reboot
of my account on there side and my internet cut out for 5 minutes and when my internet started working again
at first my email would not work saying I got wrong details but about 3 minutes after that my emails sending and receiving was all working again and no more error's. Next time I will call my ISP first.
