I was trying to send emails via PHP using PHPMailer,

I added the App password or something like that, it worked with gmail.com, but here it does not work

$mail->CharSet = "UTF-8";

$mail->SMTPDebug = 2;

$mail->isSMTP();

$myEmail = "...@hotmail.com";

$myAppPassword = "...";

$mail->Host = 'smtp.office365.com';

$mail->SMTPAuth = true;

$mail->Username = $myEmail;

$mail->Password = $myAppPassword;

$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;

$mail->Port = 587;

result:
