Office 365 API Error: Random 423 Unauthorized

    Hi there,

    I am using your FluentSMTP plugin to send emails properly.

    I’ve a coonection provider with Microsoft and I’ve properly set the app in my user Azure Portal to get the Application Client ID and secret.

    Everything seems to work smoothly. The plugin sends some emails properly. But randomly I have some failures.
    The error is always:

    {
  "code": 423,
  "message": "Unauthorized",
  "errors": [
    "Unauthorized"
  ]
}

    I tried to check for a recurring pattern on the WP side (email headers, recipients, site language) but nothing seems to stand out.

    The email user I use is from my client Microsoft Office account. A piad account so it shouldn’t be a problem of email quota s we do not send many email notifications (A maximu8m of 30 emails a day at the moment).

    Some important email notifications are not sent to my client customers.

    Please let me know if you need more information.

    Thanks a lot.

    Nathan

    Hello?@nathanbrnrd,

    The error comes when there is change/modify in the Outlook account that you have used to set up the API keys. Reauthenticating will not resolve the issue instead, you need to reconfigure API key and secret key again by following the documentation.

    Thank you

    Makes sense, I think my client changed the name of the user in the Outlook account after the API keys where produced.

    Even though the error is random ans that some emails are still being sent, I’ll give a try to your solution ??
    Will let you know if it happens again.

    Hi @amimulihsanmahdi ,

    I did reconfigure new API keys and reset the Fluent SMTP connexion to Microsift Office.
    The issue still persists.
    Some emails are sent successfully and I still get some failures with the following code:

    {
  "code": 423,
  "message": "Unauthorized",
  "errors": [
    "Unauthorized"
  ]
}

    Any other suggestions?
    Thanks a lot ??
