Hi! My friend is facing a problem in accessing his yahoo! mail, he keeps getting an error message with the code 999. What might be the issue causing it? & how to solve it? Thanks

What browser are you using? If it's Mozilla, go to Tool >options, Advance tab Under Advance tab, you will see a Network tab, click on settings, check to make sure it's set to "No proxy"... Mostly when this settings is set to "Manual Proxy configuration" , you get this 999 error when accessing Yahoo Mail on the web but some sites would still be working under a proxy ip set in the manual proxy configuration.. If you are using IE, go to Tools > internet options > connection tab, LAN settings? then untick the box that says: Use a proxy server for your LAN ( These settings will not apply to dial-up and VPN connections). You can check the box "Autromatically detect settings" if you want to. CLick on OK > Apply > OK button, then go to www.mail.yahoo.com, sign in and see if you can go to your Yahoo Mail.

This is the problem with your IP address, so you should try to yahoo mail from other server like www.yahoo.co.uk, yahoo.co.in etc
