JPST is a Microsoft Outlook .pst file library for Java. It lets you create new Outlook .pst files, edit existing .pst files and read or export messages, appointments, contacts, tasks and other items as .msg files from any .pst file. You can browse the full folder hierarchy, add, modify and delete items and attachments, and search mailbox content programmatically. The library does not require Microsoft Outlook to be installed on the machine or any other third party application or library in order to work.
