You bet for prepare an Application, written in vb.net or c# (Visual Studio 2010 or higher) that read and write the Settings from Windows 8.1 MAIL Application. Decencies should be just in .NET Framework!
Just a simple form or console Application which can Switch some Settings ON/OFF and Read/Write Text.
