Build me a simple Windows app for opening Outlook PST and OST files without needing Outlook installed. I want it to feel like a classic mail viewer with three panes, folder list on the left, messages in the middle, and the selected email and its properties on the right. It should be able to open files even if Outlook already has them open, search message headers, and show search results clearly.

Please include export options so I can save email bodies as HTML, RTF, or plain text, export selected search results as MSG files, and export message properties to CSV. If a message is signed or encrypted, show it when the matching certificate is available on the machine. I also want a basic command line tool that can export emails, attachments, or properties from a whole file or from a chosen folder inside it.

Make it straightforward to build and run on Windows, and if you need to, look up current docs online.
