FAQs

  • "Username or password error" appears during configuration, but I confirmed the password is correct.

    • Cause: The account uses a third-party client security password. The regular mailbox logon password does not work.

    • Solution: Generate a third-party client security password and use it as the client password.

  • Cannot connect to the server after checking SSL?

    • Cause: SSL is enabled but the port is still set to a non-encrypted value (110 or 143).

    • Solution: Change the port to the SSL-encrypted port: 993 for IMAP or 995 for POP3.
