MSG Properties When They Are Embedded ON A PST

[jbl1167]

I need code that may allow me to go inside a PST file, get a count and a list of the different msg files there and also the size of each one of them. Being more ambitious, if the msg contains attachments I would like to know what those attachments are and their size.

Any idea how could I do that or if a product exist that is able to do that?

Thank you
