Can't sign in to any yahoo mail ect.. - Yahoo Mail

I assume you wish to access email in a different Yahoo! Mail account. Yahoo! allows you to access only one account at a time. To sign in as a different user, you must first sign out from the account you are currently accessing.

To sign out from Yahoo! Mail, click on the "Sign out" link in the upper left corner of the web page:



Then go to the Yahoo! Mail page (http://mail.yahoo.com), and sign in with the new user ID and password.

no one is hacking to your yahoo mail, that is a spam message, maybe you sign-up on a website or something and they distribute your email address to those spam site, just delete those spam message or click the message and then click send to spam message.

When you want to sign in your yahoo account.You first enter your I.D and Password to gain access to yahoo mail. Which means from yahoo mail.Enter your I.D,when you have Yahoo I.D and Password.

signout from your mail and when signing in..........
choose the option dont remember me

You can only have one yahoo "Instant message capable" program open at one time. So if you move from Messenger to mail or chat you will get this message. If you want to have Yahoo Mail open with another Yahoo IM program you will have to set your status to "offline" in MAIL by using the dropbox next to your name ( all new mail) select "sign out of chat"
In Classic mail its located in the Inbox. Your online chat contacts will vacate the inbox until you make yourself "Available" again.
Yahoo classifies - Messenger - Mail - webmessenger - my yahoo - mobile phones - computers etc etc as different computers or devices - hence the confusion.

Try typing www.mail.yahoo.com in your browser
