I have a new bizmail account and have set up the email on my laptop - no problem. When trying to set up the same account on my iPhone (following the screenshot guide on the Yahoo page to the letter) with the same credentials, I get an error that the user ID or password is incorrect. I know that my ID and password are correct because I've been accessing the account multiple times a day on my laptop. I have several other accounts set up on the same iPhone - no problem. I deleted the account, followed by shutting down the phone for a while, but that made no difference. What am I doing wrong? Thanks!
