Adding an Attachment to an email, using QDEsktopServices

I have a very simple application to test the email service.

Code:

ui->setupUi(this);
  QString fileName=QFileDialog::getOpenFileName(this,"Attach File");
  qDebug()<<fileName;
  QDesktopServices::openUrl(QUrl("mailto:recipient@example.com?subject=Test&body=This is the body&Attach="+fileName));

I want to attach a file to the email. When i run the application the email opens but there is no attachment. The application output show a bunch of messages from a process called ShellStreams and the last message of the list is ShellStreams: Detach and the file name that i tried to attach. If i'm in other application, lets say PDF, i can attach files to the email popup. I looked on line but most of the answers where for linux. Any idea how to solve this?
Here is the output from my program:

Code:
