Is there a way to implement drag & drop from Outlook? It's very common that people drag a file from their Outlook. When I drag & drop it into the default widget, it says "Doesn't seem like a valid file."
I did some research on this and it appears that dragging and dropping from outlook to just about any application does not work, due to a lack of functionality on the part of Outlook - see https://superuser.com/questions/441747/dragging-attachments-from-outlook-into-applications.
Unfortunately, it looks like this one is out of our control.
