    Hi,

    Recently, the email functionality of our site stopped working. We have been using WP Mail SMTP since the beginning. We are emailing through office 365 outlook. None of the other similar threads I could find gave a solution.

    The only thing I can think is that we recently changed the administrator credentials for the WP dashboard, but as far as I know we did not change the credentials for the email account we’re using to send emails. Let me know where I can go to address this.

    Below is the code when I do the test email:

    Versions:
    WordPress: 4.9.2
    WordPress MS: No
    PHP: 5.5.38
    WP Mail SMTP: 1.2.5

    Params:
    Mailer: smtp
    Constants: Yes
    ErrorInfo: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
    Host: smtp.live.com
    Port: 587
    SMTPSecure: tls
    SMTPAutoTLS: bool(true)
    SMTPAuth: bool(true)

    Server:
    OpenSSL: Yes
    SMTP Debug:

    Hi,

    Authentication unsuccessful
    SMTP ERROR: Password command failed

    So it’s a good idea to check that you are actually using a correct Username (which should be an email) and Password pair in WP Mail SMTP settings.
