This project allows to parse Outlook MSG files and perform certain operations:

• Traverse structure (i.e. access attachments, embedded MSG files, recipients)
• Retrieve properties of objects
• Extract attachments and embedded MSG files (the same is true for attachments and embedded message of embedded MSG files :) ).

Project doesn't support modification of an MSG file and there is no plan of adding such a support in a near future. But it is possible to create an extension for this purpose. Code relies on the implementation of Compound Binary File format from this GIT repository: https://github.com/ifedoroff/compound-file-js .

Usage

You can find example of usage in test/example.spec.ts
