What are some common issues when setting up PHPMailer-Lite to send emails via Microsoft Exchange?

One common issue when setting up PHPMailer-Lite to send emails via Microsoft Exchange is that Exchange servers often require authentication and encryption settings to be configured correctly. To solve this, make sure to set the SMTPAuth parameter to true and specify the SMTPSecure parameter as 'tls' or 'ssl' depending on your Exchange server settings. 

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

$mail = new PHPMailer(true);

$mail->isSMTP();
$mail->Host = 'your_exchange_server_address';
$mail->SMTPAuth = true;
$mail->Username = 'your_exchange_username';
$mail->Password = 'your_exchange_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

$mail->setFrom('your_email@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');

$mail->isHTML(true);
$mail->Subject = 'Subject';
$mail->Body = 'Email body content';

if($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email could not be sent.';
}
