Drag&Drop of file item into outlook mail creates a link not attachment

If a QListView used with QFileSystemModel with Drag enabled, you can't drag&drop a file item on a outlook mail as attachment. Instead of attachment a link to the file is created.

Steps to reproduce

1) Start a new email from the Outlook

2) From the attached sample application drag&drop a file into the mail.

Compare to drag and dropping from Windows Explorer, that attach the file.
