Dijji/XstReader ? reverse-engineered prompt

Build me a simple Windows app that can open Microsoft Outlook .pst and .ost files and let me browse the mail in a classic three pane layout, with folders on the left, message list in the middle, and the selected email on the right.

I want to be able to search messages, view the body and headers, see attachments, and inspect all the message properties. It should also let me export emails in their original format, like plain text, HTML, or rich text, and export attachments or properties to files. If it makes sense, add a small command line export tool too, so I can dump a whole mailbox or just one folder into a target directory.

Please keep it working without needing Outlook installed, and make it feel like a straightforward lightweight viewer for reading mailbox files. If you need to check anything about the Outlook file format, look up the current docs online.
