This is a dev support forum. Please reach customer care if you need any help with Yahoo Mail usability. I am not sure if I got your question but just incase you are looking for changing the display name then go to your Mail options->Accounts and change it. Thanks.

I changed my "Profile" to a new last name. That works for everything but simple email.
Where do I change the original last name I gave Yahoo! when setting up my account?
Thanks.
