How to Convert OST Files to ICS Format
Converting OST files to ICS format using Aspose.Email for Java simplifies email data management. With Aspose.Email’s API, developers can easily extract email content from OST files and convert it to ICS format for better calendar compatibility ensuring the integrity of the original email data, including event details, attendees, and reminders. This streamlined process ensures a smooth transition and enhanced data portability across various platforms. Incorporating Aspose.Email into Java applications enables efficient email management and scheduling.
To convert OST files to ICS 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 MapiCalendar class represents a calendar item extracted from the loaded MapiMessage. It provides properties and methods for working with calendar-specific data, such as appointments, events, and reminders. The AppointmentSaveFormat enum is used to export and share calendar data. In the code sample below, these classes work together to extract calendar items from an OST file, convert them into the .ics format, and save them as individual files in the specified output directory.

Steps to Convert OST to ICS via Java
Java programmers can easily convert OST file to ICS in just a few lines of code.
- Open the OST file using PersonalStorage.fromFile method.
- Make sure the output directory exists by creating a new File object using the outputDirectory path and calling mkdirs().
- Get the Appointments (Calendar) folder from the OST file using getPredefinedFolder .
- Iterate through the messages in the Calendar folder using a for loop and msg variable.
- Inside the loop, check if the message is a calendar item with MapiItemType.Calendar and if so, convert it to a MapiCalendar object.
- Save the calendar item as an .ics file in the output directory by calling the save 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.
- Get latest version of Aspose.Email for Java directly from Maven .
Convert OST to ICS - Java
// Open the OST file
PersonalStorage ost = PersonalStorage.fromFile(ostFilePath);
// Ensure the output directory exists
new File(outputDirectory).mkdirs();
// Get the Appointments (Calendar) folder from OST
FolderInfo calendarFolder = ost.getPredefinedFolder(StandardIpmFolder.Appointments);
// Iterate through OST messages and save calendar items as .ics files
int count = 1;
for (MapiMessage msg : calendarFolder.enumerateMapiMessages()) {
// Search a calendar view and save it as .ics file
String icsFilePath = outputDirectory + File.separator + "Message" + count + ".ics";
if (msg.getSupportedType() == MapiItemType.Calendar) {
MapiCalendar calendar = (MapiCalendar) msg.toMapiMessageItem();
calendar.save(icsFilePath, AppointmentSaveFormat.Ics);
}
System.out.println("Message " + count + " saved as: " + icsFilePath);
count++;
}
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 ICS File Format?
The ICS (iCalendar) file format is a widely used standard for storing and exchanging calendar and scheduling information, including events, tasks, appointments, and reminders. The ICS file format uses a human-readable text-based structure that contains details such as event title, description, location, start and end times, and participant information, allowing users to easily share and import calendar data across different platforms and applications.
