Converting .msg to .eml using java

Question

In our application, we are required to convert .msg files to .eml format in Outlook 2010. I would like to implement this using Java API. However, I would like clarification on the following:

1. What is the difference between the .msg and .eml format?
2. Are there any current Java APIs to convert the .msg format to .eml format?

Answer 1

1. The Outlook .msg file format is based on Outlook Item (.msg) File Format. The .eml file format represents messages on RFC822 / MIME format. Formats are very different.

2. JMSG is third party Java library with functionalities to convert .msg <-> .eml
