How can I import my address book from my old email address, sbcglobal.net, to my yahoo email address?

im not sure but try this: highlight the e-mail adddresse then go to edit then select cut or copy then you can go back to edit then paste them to your new adress book hope this works out for you good luck

This depends on whether you use an email client software such as Outlook. If so you should be able to export your addys to yahoo. If not the fastest way would be to logon to your old email and forward messages to your yahoo account and then add to contacts or address book. The other option is to logon to your old email open another tab in IE logon on to your yahoo email and copy and paste addys to the yahoo account!
