Extracting all .msg files from a .pst file

Question

Note: I was asked to create an app that extracts .msg files from a .pst file preferably in MFC. I was informed that they have tried to use other 3rd party apps but they all fail

Answer 1

If you really need to write your own application, then you must start by searching and downloading the PST specification. LMGTFY... Ah, you can find it on MSDN:

[MS-PST]: Outlook Personal Folders (.pst) File Format.

Only then can you determine what tools you need for the job, and which programming languages will help you best.

It looks like a well specified binary format. So any language that will allow you to read binary files (both MFC and C# can do this well) will do the job. There may be third-party libraries available for reading .PST files, but you'll really have to search those yourself and evaluate them according to your criteria. For example:

• NMapi - C# MAPI Library

Answer 2

MSG .NET (C# library).
It does exactly what you need, extract all messages as .msg files from a .pst file.
