How do I export Outlook Calendar to ICS without losing event details?

    To export your Microsoft Outlook calendar to ICS file without losing event details, start by opening Outlook and switching to the Calendar view. Select the specific calendar you want to export. Go to File → Save Calendar. In the options window, choose a date range such as “Whole calendar” to avoid missing recurring or older events. Set the format to iCalendar (.ics).

    Click “More Options” and ensure you include full event details like description, location, reminders, recurrence patterns, and attachments (if supported by your version). Choose a clear file name and save location.

    After exporting, open the ICS file in a text viewer or import it into another calendar app such as Google Calendar or Apple Calendar to verify that recurring meetings, time zones, and notes are preserved.

    If anything looks incomplete, re-export with a broader date range and check that your Outlook profile is fully synced before exporting. Avoid editing the ICS file manually, as that can break event formatting and cause missing details during import.
