MSG is still supported—just select a few messages and drag and drop them outside into a folder. It is very useful, and Microsoft should never discontinue this. This is especially beneficial for longer projects where many people work at different times over a few months to a year, allowing them to access earlier communications from MSG files saved in respective folders. I have seen many organizations using this, and I personally use it a lot as well.

PDFs are handled one by one, and that still results in some functionality loss. Since "Markitdown" is from Microsoft itself and MSG files internally have an HTML-based backend for formatting, it would be nice to have such functionality. This would allow users to import them into a database or directly run formatting processes, which would provide better support for AI models.
