    Hi
    Trying to set up the plug in for a client using the other SMTP setting. They don’t want to go for the pro version that handles Outlook. I have never had any issues setting up before when I use gmail accounts. We have use the correct email user and password and have authentication on at the email hosting.

    This is the error I am getting. Can you tell me where we are going wrong?

    Versions:
WordPress: 5.8
WordPress MS: No
PHP: 7.3.29
WP Mail SMTP: 3.0.3

Params:
Mailer: smtp
Constants: No
ErrorInfo: SMTP Error: Could not authenticate.
Host: SMTP.office365.com
Port: 587
SMTPSecure: tls
SMTPAutoTLS: bool(true)
SMTPAuth: bool(true)

Server:
OpenSSL: OpenSSL 1.1.1d 10 Sep 2019
Apache.mod_security: No

Debug:
Email Source: WP Mail SMTP
Mailer: Other SMTP

    Hi @sfblack,

    Thanks for reaching out. According to the log:

    2021-08-11 10:26:29 SMTP ERROR: Password command failed: 535 5.7.139 Authentication unsuccessful, the request did not meet the criteria to be authenticated successfully. Contact your administrator.

    There’s a security policy within your account that isn’t allowing you to authenticate. Probably your account has SMTP Authentication disabled, you can check this tutorial to enable SMTP authentication and/or contact your Office 365 administrator to look into your account issues.

    Just a note, SMTP host is usually written as smtp.office365.com, you don’t need to write SMTP in capital letters.

    I hope this helps!
