    Hello WordPress Members,

    The IT specialist has fully set up FluentSMTP as per the documentation, but we are encountering the following errors:

    Server Response
    {
    “code”: 422,
    “message”: “Not Found”,
    “errors”: [
    “Not Found”
    ]
    }

    Email Headers
    {
    “reply-to”: [],
    “cc”: [],
    “bcc”: [],
    “content-type”: “text/html”
    }

    The error code 422 is mentioned on the FluentSMTP website as indicating that the mailbox is full, however, only 7GB of the 49GB is in use.

    Does anyone have any idea why it’s not working?

    Hello there,

    For Outlook connection in Fluent SMTP, we recommend generating the API and secret key using the email that you want to use as a From Email. So, if you would like to use?[email protected]?as from email then you need to generate the keys using that email. Generating the API with other email might cause permission issues as Outlook have different permission for different accounts. Also, after generating the API kindly make sure that you are authenticating with the same email. In other words, the From email should be used to generate API keys and authenticate.

    So, if you are not using the From Email to generate the API key and Secret key, then you need to delete the existing connection and credential and then, reconfigure it again.

    Thank you
