I need to add outgoing password onto aol. Messages and emails come in but not out

Settings/Passwords & Accounts. Tap on the account, then SMTP (outgoing) and add your AOL ID and password. But, as razmee209 says, it’s easier to just delete the account, restart your phone and add it back.

settings - account and password - aol - see if you can add a password, otherwise delete and reinstall the mail account
