PHPMailer：如何从Outlook电子邮件发送电子邮件？

问：

我正在使用 PHPMailer 通过我的 Outlook 电子邮件发送电子邮件，但我一直收到此错误

Message could not be sent. Mailer Error:
"The following From address failed: [email protected] : 
MAIL FROM command failed,Client not authenticated to send mail. [
xxxxxx.namprd13.prod.outlook.com 2023-07-14T21:47:08.967Z 08DB842E797B0C23]\r\n,530,5.7.57SMTP server error: MAIL FROM command failed Detail: Client not authenticated to send mail.

我正在使用沙盒 outlook 电子邮件，这可能是问题所在，但对此表示高度怀疑，因为我能够使用 ms-graph-sdk 发送消息

这是我的代码：

try {
    //Server settings
    $mail->SMTPDebug  = SMTP::DEBUG_SERVER;
    $mail->Host       = 'smtp-mail.outlook.com'; //smtp.office365.com:587
    $mail->Username   = '[email protected]';
    $mail->Password   = 'xxxxxxxxxx';
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
    $mail->Port       = 587;
    $mail->isSMTP();
    //$mail->SMTPAuth   = true;

    //Recipients
    $mail->setFrom('[email protected]', 'Mailer');
    $mail->addAddress('[email protected]');

    //Content
    $mail->isHTML(true);
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    if (! $response = $mail->send()) {
        Log::info('Message could not be sent.');
        Log::info('Mailer Error: ' . json_encode($mail->ErrorInfo));
        exit;
    } else {
        echo 'Message of Send email using Outlook SMTP server has been sent';
    }
    echo 'Message has been sent';
}
catch (Exception $e) {
    Log::info("Message could not be sent. Mailer Error:" . json_encode($mail->ErrorInfo));
}
