Every time I try to add my yahoo mail. It is always saying wrong user name and invalid password. But, I know it's right. How do I add pls. Help thanks!
Have you verified logging into your yahoo account via a PC to make sure you have the correct login credentials?
If you have verified that your email and password are correct, go to manual setup and change the security to none and the incoming mail servier for incoming to incoming.yahoo.com and then for outgoing no security and change it to outgoing.yahoo.com that should fix it.
