How to Convert PST Files to MSG Format
When working with PST files in Java, Aspose.Email provides a robust solution for converting these files to MSG format. By utilizing the PersonalStorage class, users can easily open and access the contents of the PST file. The process involves retrieving the desired folder, such as the Inbox, and iterating through the messages within it using the enumerateMapiMessages() method. Each MapiMessage can then be saved individually in MSG format by invoking the save() method with the appropriate SaveOptions. Aspose.Email for Java streamlines the conversion process, allowing for seamless transformation of PST files into MSG format while maintaining the integrity of the email content. The library’s functionality and ease of use make it a valuable tool for handling email file formats in Java applications.
To implement PST to MSG conversion functionality into a Java application, the library offers the PersonalStorage class which is used to open a storage file, allowing access to its content and structure. The FolderInfo class represents a folder within the storage file and makes it possible to manipulate its content. The MapiMessage class provides developers with a comprehensive set of functionalities to work with email messages programmatically, enabling them to efficiently manage, manipulate, and interact with email data within their Java applications. The collection of email messages is stored with the MessageInfoCollection class. With the MessageInfo class, representing information about a specific email message, you can access details of each email message within a folder. The SaveOptions class provides options for saving email messages in different formats. It allows for customization of the saving process based on the specific requirements. In the code sample below, these classes work together to open an Outlook PST file, retrieve messages from the Inbox folder, extract each message as a MapiMessage, and save them as .msg files in a specified destination folder.

Steps to Convert PST to MSG via Java
Java programmers can easily convert PST file to MSG in just a few lines of code.
- Open the Outlook PST file with the PersonalStorage.fromFile method.
- Retrieve the contents of the Inbox folder using the getPredefinedFolder method.
- Get the collection of MessageInfo objects representing information about email messages from the folder.
- Iterate through each MessageInfo object in the collection.
- Extract each MessageInfo object as a MapiMessage.
- Save each MapiMessage as a .msg file in the “DestFolder” directory with a unique filename based on the loop index i.
System Requirements
Before running the Java conversion code, make sure that you have the following prerequisites.
- Microsoft Windows or a compatible OS with Java Runtime Environment for JSP/JSF Application and Desktop Applications.

What is PST File Format?
PST (Personal Storage Table) is a file format used by Microsoft Outlook to store email messages, contacts, calendars, tasks, and other mailbox items. PST files function as a data storage container that allows users to access and manage their email data within Outlook. These files can be created and saved locally on a user’s computer or stored on a network server. PST files are commonly used for backing up email data, archiving old messages, and migrating email data between different computers or email clients. Additionally, PST files can be password-protected to enhance data security and privacy.
What is MSG File Format?
MSG is a file format used by Microsoft Outlook to store emails, contacts, calendar items, tasks, and other information. An MSG file contains all the components of an email, including the message body, attachments, sender and recipient information, subject, date, and other metadata. This format allows users to save individual email messages or entire folders in a single file for easy storage and sharing. MSG files can be opened and viewed by Microsoft Outlook and some other email clients, but may not be compatible with all email programs.
