O365 Not sending emails from WordPress

  • I have WP Mail SMTP Pro plugin setup using the launch wizard. When I try to send an email, it sends successfully, but in the Outlook O365 I am getting the following error. I contacted Microsoft and they said that in Dec 2022 they disabled basic authentication.

    Is there a solution for this?

    Remote server returned ‘550 5.7.708 Service unavailable. Access denied, traffic not accepted from this IP. For more information please go to https://go.microsoft.com/fwlink/?LinkId=526653 AS(7230) [YT1PR01MB9004.CANPRD01.PROD.OUTLOOK.COM 2023-08-18T07:56:36.449Z 08DB9FA3E502DCE6]’

    “WP Mail SMTP Pro“

    Support of all commercial themes and plugins is out of scope for these forums. While we will not close your post, we also cannot guarantee any support at all, be that by volunteers or the developers. We recommend you instead use the developer’s official contact for their premium offerings, as that is the most direct line..
