    I installed Fluent SMTP on my WordPress website. My email is on Microsoft 365. I installed and configured the plagin as per the documentation. But the test email fails with the following error.

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

    Please help

    Hello @sameerpanje,

    Can you please check if you have set the From Email that you have used to generate the API keys? If not, kindly update the From Email with the one that you have used to generate API keys.

    In addition, if you are using any alias/group emails as From Email then kindly make sure that you have generated the API keys using that email.

    Thank you

    There is a Gotcha with this one, “423,”message”: “Forbidden” The Account your using must be the account to complete the entire app registration including setting the permission, you CANNOT complete the registration/approve the permission with a different admin account! you may need to adjust the app registration permission settings in the Tenant or give the account temp admin, these can be removed once the registration is complete.
