How can the code be modified to ensure compatibility with Outlook for emails sent through Swiftmail?

To ensure compatibility with Outlook for emails sent through Swiftmail, you can modify the code to include the proper headers that Outlook recognizes. Specifically, you should include the "Content-Type" and "Content-Disposition" headers to ensure that the email displays correctly in Outlook. 

// Set the headers for Outlook compatibility
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= 'Content-Disposition: inline' . "\r\n";

// Send the email using Swiftmail
$message = (new Swift_Message('Subject'))
    ->setFrom(['your_email@example.com' => 'Your Name'])
    ->setTo(['recipient@example.com' => 'Recipient Name'])
    ->setBody('Hello, this is a test email', 'text/html');

// Create the Transport
$transport = new Swift_SmtpTransport('smtp.example.com', 25);
$mailer = new Swift_Mailer($transport);

// Send the message
$result = $mailer->send($message, $failedRecipients);

if ($result) {
    echo 'Email sent successfully';
} else {
    echo 'Failed to send email';
}
