How to Convert ICS Files to PST Format

Converting ICS files to PST format can be beneficial for several reasons. PST files are commonly used for storing emails, contacts, calendars, and other data in Microsoft Outlook. By converting ICS files to PST format, you can easily integrate calendar events, tasks, and appointments from different platforms into Outlook, allowing for better organization and synchronization of your schedule.

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 PST 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. With the FolderInfo class representing the information about personal folders in a mail storage, you can create, delete, rename, and retrieve folders within a mail storage, as well as perform various operations on the messages stored in these folders. And finally, the MapiMessage class represents an Outlook message (MSG) item. In the code snippet below, these classes work together to effectively convert calendar appointments stored in an ICS file into a format compatible with Microsoft Outlook, allowing users to import and view the appointments in their Outlook calendar.

Steps to Convert ICS to PST via Java

Java programmers can easily convert ICS file to PST in just a few lines of code.

  1. Load the ICS file “MyFile.ics” to be converted into an Appointment object using Appointment.load method.
  2. Save the Appointment object as a MSG file using ByteArrayOutputStream named msgStream.
  3. Create a PST file named “SavedFile.pst” with Unicode format version using the PersonalStorage.create method. This method returns a PersonalStorage object ‘pst’.
  4. Create a calendar folder named “Calendar” within the PST file using createPredefinedFolder() method with StandardIpmFolder.Appointments as the folder type.
  5. Convert the MSG file from ByteArrayOutputStream to a MapiMessage object.
  6. 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 PST - Java

// Load the ICS file to be converted
Appointment appointment = Appointment.load("MyFile.ics");
// Save ICS as MSG
ByteArrayOutputStream msgStream = new ByteArrayOutputStream();, AppointmentSaveFormat.getMsg());
// Create a PST file
PersonalStorage pst = PersonalStorage.create("SavedFile.pst", FileFormatVersion.Unicode);
// Create a calendar folder
FolderInfo calendarFolder = pst.createPredefinedFolder("Calendar", StandardIpmFolder.Appointments);
// Add MSG to the calendar folder
ByteArrayInputStream inputStream = new ByteArrayInputStream(msgStream.toByteArray());
MapiMessage mapiMessage = MapiMessage.fromStream(inputStream);

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 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.
