Error message says attempt to connect to my Verizon account failed. I opened account settings, wrote name and password, but nothing changed.
Is this a Verizon / AOL account?
You can check your settings in Menu > Tools > Accounts.
POP3:

security policy: Use SSL/TLS on special port (legacy)
SMTP:
port: 465
security policy: Use SSL/TLS on special port (legacy)
IMAP:

If the settings are correct, and you still can’t connect, try disabling your anti-virus and firewall and try again.
