How to Convert OST Files to EML Format
Converting OST files to EML format using Aspose.Email for .NET is a straightforward process that empowers developers to efficiently manage email data. Aspose.Email provides a convenient API to read OST files, extract email messages, and convert them to the universally recognized EML format. This conversion preserves the original formatting, attachments, and metadata of the emails, ensuring a seamless transition. By leveraging Aspose.Email’s robust conversion capabilities, developers can seamlessly integrate OST to EML conversion functionality into their applications, facilitating interoperability and data portability across different email platforms and systems.
Aspose.Email for Java is a powerful API that provides comprehensive functionality for working with email messages, contacts, calendars, and tasks in Java applications. To convert OST files to EML format, 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. In the code sample below, these classes work together to open an OST file, retrieve messages from the Inbox folder, extract and save each message as an EML file in a destination folder.

Steps to Convert OST to EML via Java
Java programmers can easily convert OST file to EML in just a few lines of code.
- Load the OST file “Outlook.ost” with the PersonalStorage.fromFile method.
- Retrieve the predefined Inbox folder from the loaded OST file using the getPredefinedFolder .
- Get the contents of the Inbox folder as a collection of email message information using the getContents method of the FolderInfo class.
- Iterate through each email message in the MessageInfoCollection.
- For each email message, extract the message information using the MessageInfo class.
- Extract the MAPI message from the OST file using the PersonalStorage.extractMessage method.
- Save the extracted MAPI message as an EML file in the destination folder “DestFolder” with a filename based on the index using the MapiMessage.save method and SaveOptions.getDefaultEml() options.
System Requirements
Before running the Java conversion code, make sure that you have the following prerequisites.

What is OST File Format?
OST (Offline Storage Table) file format is a file that stores a copy of mailbox items from an Exchange server, allowing users to access their mailbox data even when they are offline. OST files are synchronized with the Exchange server when a connection is established, ensuring that any changes made offline are updated on the server as well. OST files are used by Microsoft Outlook for email, contacts, calendars, tasks, and other mailbox items in an Exchange environment.
What is EML File Format?
EML file format represents email messages saved using Outlook and other relevant applications. Almost all emailing clients support this file format for its compliance with RFC-822 Internet Message Format Standard. Microsoft Outlook is the default software for opening EML message types. EML files can be used for saving to disc as well as sending out to recipients using communication protocols.
