Could you build this?
Partial Building the UI wrapper is trivial, but parsing proprietary, binary Microsoft Outlook OST and MSG file structures requires reverse-engineered format specifications or low-level binary parsing libraries.
What it would actually take: The software must parse proprietary binary formats (MS-PST/OST file specifications) and re-serialize them into OLE Compound Document (MSG) formats. Developers typically write C#/.NET or C++ utilizing native MAPI or open-source low-level parsing libraries like libpff. Expertise in binary stream parsing, message property mapping, and handling corrupted offline storage tables without data loss is essential.
