Outlook Message Parser

Outlook Message Parser is a small open source Java library that parses Outlook .msg files.

<dependency>
  <groupId>org.simplejavamail</groupId>
  <artifactId>outlook-message-parser</artifactId>
  <version>1.9.6</version>
</dependency>

Outlook Message Parser is a continuation (or fork if that project independently continues) of msgparser.

Under the hood it uses the Apache POI - POIFS library to parse the message files which use the OLE 2 Compound Document format. Thus, it is merely a convenience library that covers the details of the .msg file. The implementation is based on the information provided at fileformat.info.
