Cannot access Yahoo Small Business email using Mail icon on main screen of IPad

Until recently I was able to access my Yahoo Small Business email using the main Email button on the home screen - along with my regular Yahoo email. When i contacted Yahoo Small Business for help, the gentleman was unable to help. He just gave me the link to setting up a Yahoo Account on Ipad. My regular Yahoo mail works fine so this wasn't helpful. He said that is all he can do.

I downloaded the Yahoo App and can access both email address from it, but it is less convenient. This tells me it isn't a password issue.

I have tried using:

Incoming mail (POP3) server

pop.bizmail.yahoo.com

use SSl

Port: 995

Outgoing mial (SMTP) server

smtp.bizmail.yahoo.com

use SSL

Port 465 or 587

If anyone can send me the correct steps to set up my small business email so that I can access it via the main button (which I was able to do until recently!), I would appreciate it. In addition, I access both via my Yahoo account on my laptop - no problem. I am using an iPad 2 that was upgraded to Version 7.
