OutLook File Formats

[MWE]

I am looking for a tutorial/article/something that will
help me understand the specific content and internal
formats for various Outlook files, e.g., pab, pst, ost,
oab, etc. I know generally what each file is/does, I need
details on how they are structured.

Thanks

afaik, the file structures are proprietary and not documented.
