我尝试使用PHPMailer发送电子邮件，但出现错误：

Question

我正在尝试使用PHPMailer发送电子邮件，并从我网站上的Contact-Formular发送数据，但这不起作用。

我已经尝试使用用户说对他们有用的代码，但这对我也不起作用。

check_contact_form.php

<?php
session_start();

if(isset($_POST['Name']) && isset($_POST['E-Mail']) 
   && isset($_POST['Anliegen']) &&!empty($_POST['Name'])
   && !empty($_POST['E-Mail']) && !empty($_POST['Anliegen'])) {

    $Name = $_POST['Name'];
    $Telefonnummer = "-";

    if(isset($_POST['Telefonnummer']) 
           && !empty($_POST['Telefonnummer'])) {
        if(is_numeric($_POST['Telefonnummer'])) {
            $Telefonnummer = $_POST['Telefonnummer'];
        } else {
               $_SESSION['errorMsg'] = 'Die eingegebene Nummer besteht 
                      nicht nur aus Zahlen!';
           header('Location: contact.php');
        }
        }

    require_once('PHPMailer/PHPMailerAutoload.php');

    $mail = new PHPMailer(true);
    $mail->isSMTP();

    $email_body = "";
    $email_body = $email_body . "Name: " . $Name . "<br>";
    $email_body = $email_body . "Email: " . $_POST['E-Mail'] . "<br>";
    $email_body = $email_body . "Message: " . $_POST['Anliegen'];

    $mail->IsSMTP();
    $mail->SMTPDebug = 0;
    $mail->SMTPAuth = true;
    $mail->SMTPSecure = "STARTTLS";
    $mail->Host = "SMTP.office365.com";
    $mail->Port = 587;
    $mail->Username = "my-email";
    $mail->Password = "my-password";

    $mail->SetFrom($_POST['E-Mail'], $Name);
    $address = "my-email";
    $mail->AddAddress($address);
    $mail->Subject    = "Anliegen per Website " . $Name;
    $mail->IsHTML(true);
    $mail->Body = $email_body;

    if($mail->Send()) {
        $_SESSION['errorMsg'] = 'Sie haben nicht alle Felder mit 
                                         einem Stern ausgefüllt!';
        header('Location: contact.php');
        exit;
    } else {
        $error_message = "Ein Fehler ist aufgetreten: " .     
                                  $mail->ErrorInfo;
    }

} else {
    $_SESSION['errorMsg'] = 'Sie haben nicht alle Felder mit einem 
                                 Stern ausgefüllt!';
    header('Location: contact.php');
}

?>
