check your netowork connections and make sure they are set, also check your browsers security and you may need to update it

Try closing your browser and then reloading. Still not working? Reboot the machine. Still not working? try another machine.\n\nMy Yahoo is still working fine, you probably have a Java Error or loggin issue that is stopping the loading of the page.

the yahoo servers act crazy sometimes. it happens to many users. \nyahoo servers do not communicate with each other in the best way on MYYAHOO.

I think there was some slight problem with Yahoo's login pages earlier. try again, it should be ok now.

May be you not tick mark on the preference that always sign in to my mobile device when i exit messenger. so please tick mark on that and you always get online with your mobile. Or just go in to edit my device option and again register your device in yahoo messenger service. Hope this will beneficial to you.

I have the same problem! And... I have a lot of trouble signing in initially too... \n\nI reformatted my computer recently and re-downloaded AIM and it still has the same problems... I think its just their program. I stick to Yahoo! It works a lot better.

I think Yahoo was having glitches, a few people mentioned that they couldn't get their mail.  Try signing into the other places on Yahoo, like games or something, then go to mail.  Works for me sometimes!

leave yahoo messenger behind and use AIM. Yahoo has always had problems with me and i have never had one with Aol Instant Messenger (AIM)

i have that same problem when i try to enter yahoo games.  it might be related to java or you may need to clear your temporary files.  see if you can contact yahoo! customer support.  they're available 24/7.

Are you logging into the right domain. Also there have been times I've changed a password and had the caps on when I changed it not really paying much attention and when trying to log back on I didn't have caps on so I couldn't log in.

This sounds like an issue with the server.  You just have to keep trying until it allows you through.  Hit your refresh button every few minutes or so.

Can you even Sign-In to your mail account?\nIf yes, then you should be able to see a link to INBOX.\n\nSometimes you can't sign-in because the mail server is down. Try again later.

Working just fine from here.\nIf it's a particular group that you can't access, Y may have shut it down (for reasons that are often hard to fathom)\nIf it's the whole groups front-end (groups.yahoo.com), then the problem may be local to you...  try flushing the cache on your browser, in case there's been a problem or change that got cached.
