How to Convert OST Files to MBOX Format
Converting OST (Outlook Offline Storage Table) files to MBOX format using Aspose.Email for Java offers a convenient solution for efficiently handling email data. Aspose.Email’s user-friendly API empowers developers to effortlessly parse OST files, extract email content, and convert it into MBOX format. This conversion process ensures the preservation of the original email layout, attachments, and metadata, guaranteeing a seamless transition between formats. By leveraging Aspose.Email’s reliable conversion tools, developers can easily integrate OST to MBOX conversion functionality into their applications.
To convert OST files to MBOX format, the library offers the PersonalStorage class which is used to open a storage file, allowing access to its content and structure. The MboxrdStorageWriter class is used to write email messages to an MBOX file in the corresponding format. 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. When converting MAPI messages to MailMessage objects, the MailConversionOptions class is used to specify options for converting. The MailMessage class represents an email message and provides methods for accessing and manipulating email content, such as sender, recipients, subject, body, attachments, etc. In the code sample below, these classes work together to open an OST file, iterate through each folder and message in the file, convert MapiMessages to MailMessages, and write them to an MBOX file using the MboxrdStorageWriter.

Steps to Convert OST to MBOX via Java
Java programmers can easily convert OST file to MBOX in just a few lines of code.
- Open the OST file using the PersonalStorage.fromFile method and providing the path to the OST file (ostFilePath).
- Create an instance of MboxrdStorageWriter with the output path for the MBOX file and a boolean parameter indicating whether to append to an existing file (false in this case).
- Iterate through each folder in the OST file.
- Within the folder iteration loop, iterate through each message in the current folder by looping through MapiMessage objects.
- Convert each MapiMessage object to a MailMessage object using the toMailMessage method with MailConversionOptions, and write the MailMessage to the MBOX file using writer.writeMessage method.
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.

Convert OST to MBOX - Java
// Open the OST file
PersonalStorage ost = PersonalStorage.fromFile(ostFilePath);
// Initialize Mbox storage writer
MboxrdStorageWriter writer = new MboxrdStorageWriter(mboxFilePath, false);
// Iterate through each folder in the OST file
for (FolderInfo folder : ost.getRootFolder().getSubFolders()) {
// Iterate through each message in the folder
for (MapiMessage msg : folder.enumerateMapiMessages()) {
// Convert MapiMessage to MailMessage and write to MBOX
writer.writeMessage(msg.toMailMessage(new MailConversionOptions()));
}

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 MBOX File Format?
The MBOX file format is a standard format for storing and organizing email messages in a concatenated format within a single file. It typically consists of a collection of email messages, each separated by a “From” header, making it a common choice for archiving and transferring emails across different email clients and systems.
