I Am using Window 8.1, and there is a pre installed application "Mail".
I am unable to resize the view bar of this application.
In main window left side is for folders, middle for details like sender,date and time etc. & right side show the preview of message.
I want to size the right side (preview of message) but unable to drag the slide in any of the side.
From the keyboard I can open the message in a separate window but want to adjust the size in the main window as we do in MS Outlook.
