How to Convert ICS Files to OST Format
Converting ICS (iCalendar) files to OST (Outlook Offline Storage Table) format can be beneficial for users who want to access their calendar events and appointments offline, especially when working with Outlook. By converting ICS files to OST format, users can synchronize and store their calendar data locally on their devices, allowing them to view and manage their schedules without an internet connection.
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 ICS files to OST format, the library offers an Appointment class used to load and save calendar events, create new appointments, edit them and more. The PersonalStorage class of the library represents a personal storage (PST) file, which is used to store Outlook data, including emails, contacts, and calendar items. The FolderInfo class represents a folder within a PST file and provides methods for managing messages within that folder. And finally, the MapiMessage class represents an Outlook message (MSG) item. Overall, the code snippet below demonstrates how these classes can be used to manage and manipulate calendar appointments in Outlook data files. For more information about the API high code features, please visit our reference resources .
Steps to Convert ICS to OST via Java
Java programmers can easily convert ICS file to OST in just a few lines of code.
- Load the ICS file “MyFile.ics” to be converted into an Appointment object using Appointment.load method.
- Save the Appointment object as a MSG file using ByteArrayOutputStream named msgStream.
- Open an OST file “SavedFile.ost” as a PersonalStorage object.
- Get a calendar folder named “Appointments” from the PersonalStorage object using getPredefinedFolder(StandardIpmFolder.Appointments) . Store the folder information in a FolderInfo object named ‘calendarFolder’.
- Convert the MSG file from ByteArrayOutputStream to a MapiMessage object.
- Add the MapiMessage object to the calendar folder using addMessage() 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 ICS to OST - Java
// Load the ICS file to be converted
Appointment appointment = Appointment.load("MyFile.ics");
// Save ICS as MSG
ByteArrayOutputStream msgStream = new ByteArrayOutputStream();
ics.save(msgStream, AppointmentSaveFormat.getMsg());
// Open an OST file
PersonalStorage pst = PersonalStorageFromFile("SavedFile.ost");
// Get a calendar folder
FolderInfo calendarFolder = pst.getPredefinedFolder(StandardIpmFolder.Appointments);
// Add MSG to the calendar folder
ByteArrayInputStream inputStream = new ByteArrayInputStream(msgStream.toByteArray());
MapiMessage mapiMessage = MapiMessage.fromStream(inputStream);
calendarFolder.addMessage(mapiMessage);
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.
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.
