How to Convert OLM Files to ICS Format
Converting OLM files to ICS (iCalendar) format can be beneficial for users who need to access calendar information stored in Outlook for Mac on different calendar applications or platforms that support the ICS format. By converting OLM files to ICS, users can easily share, synchronize, and integrate calendar events and appointments across various calendar applications, devices, and platforms. This conversion enables seamless management and access to calendar data from Outlook for Mac on a wider range of calendar tools and services.
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 OLM files to ICS format, the library offers the OlmStorage class used to open and access the content of an OLM (Outlook for Mac) file. The FolderInfo class represents a folder within the OLM 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. With the MapiCalendar class, you can access, modify, create, and manage calendar events found in an email, also handle recurrence patterns, convert calendar items to different formats, synchronize calendar data, and generate reports. And finally, the AppointmentSaveFormat enumeration, provided by Aspose.Email, specifies the format in which the calendar item should be saved. In the code sample below, these classes work together to open an OLM file, retrieve the Calendar folder, iterate through the messages in the folder, check if the message is a calendar item, convert it to MapiCalendar type, and save the calendar item in ICS format.

Steps to Convert OLM to ICS via Java
Aspose.EMAIL API makes it easy for the developers to convert OLM file to ICS in just a few lines of code.
- Open the OLM file using the OlmStorage.fromFile method, passing in the file path of the OLM file.
- Get the Calendar folder from the OLM file using the getFolder method, specifying the folder name as “Calendar” and setting the boolean parameter to true.
- Iterate through the messages in the Calendar folder using a for loop and the enumerateMapiMessages method of the FolderInfo object.
- Check if the message is a calendar item by using the getSupportedType method to verify it is of type MapiItemType.Calendar .
- If the message is a calendar item, convert it to a MapiCalendar object using the toMapiMessageItem method.
- Save the calendar item in ICS format by calling the save method on the MapiCalendar object, appending the subject of the message to the file name, and using AppointmentSaveFormat.Ics as the save format.
