Could you build this?
Partial The UI and batch workflow are easy, but reading OST files requires parsing a proprietary Outlook format, which is hard to do reliably without existing libraries or deep format knowledge.
What it would actually take: A real version needs a parser for the Microsoft OST/PST binary format, typically built on a library like libpff or a commercial MAPI component, with a writer that produces valid PST output. The difficult parts are corrupt or partial OST files, large mailboxes, and fidelity of folders, attachments, and metadata. This requires binary format expertise and extensive testing against real Outlook files.
