Settings - email and accounts - one of my e-mail accounts says Attention required - Manage    Fix

Have tried deleting password and adding a new one, to correct but nothing is working.  If I delete the e-mail account will I lose all of my e-mails?

I can't log in to my e-mail account and I thought the "attention required" might be the problem.

This is the error message I'm getting:  Unable to send or receive messages for the sbcglobal account. An incorrect password was entered. The next time you send or receive messages, you'll be asked to enter your user name and password for this account.
