Answer 1

I got the solution,
In my code, i use both createAttachment and addAttachment, thats why my mail send with duplicate attachment.
Remove addAttachment and its working fine.
$fileContents = file_get_contents("public/uploads/Mailexcel/".$name);
$file = $mail->createAttachment($fileContents);
$file->filename = "excel.xlsx";
$mail->addAttachment($file); // Remove this
$mail->send();
