Some users are unaware of the new web URL that they must use to access the page. The specific URL is AT&T net, from which you can access all previous versions of the email. If you have an account with ATT, you can use the same login credentials to access the account on SBCGlobal net. Start using your credentials to access your ATT mail. Even third-party email clients can use these login credentials. If you prefer to access your email through Microsoft Outlook, use the same login credentials and begin reading messages from the inbox folder. Att and Yahoo have now amalgamated, and they are working together to provide the greatest services to clients. If you have an account with Yahoo or ATT, go to the ATT Yahoo Login page and log in with your login username and password. Check the URL that was opened if there is an issue.
