How to Export Outlook Calendar to ICS Format?

Has anyone tried to export Outlook Calendar to ICS when dealing with multiple calendars stored across different PST files? I recently faced this challenge while migrating schedules from Outlook to a mixed environment, and manual export quickly became impractical. That’s where the SysInfo PST Converter Tool made a noticeable difference. Instead of exporting calendars one by one, the tool supports bulk conversion, allowing multiple Outlook calendars to be extracted and saved as ICS files in a single operation. This feature is especially useful for professionals managing several mailboxes or archived PST data. During the export Outlook Calendar to ICS process, the software maintains calendar hierarchy, recurring events, reminders, and meeting details without any distortion. Unlike Outlook’s built-in options, bulk processing saves significant time and reduces the risk of missing critical events. For organizations or power users with heavy scheduling data, this bulk export capability simplifies calendar migration and ensures everything remains accessible across platforms like Google Calendar, Apple Calendar, and other ICS-compatible apps.
