Export your iCloud calendar as an iCal file
To import an iCloud Calendar to Microsoft Outlook, you will first have to export your iCloud calendar into your computer as an iCal (.ics) file. Below are the steps.
1) Open iCloud calendar by typing www.icloud.com into a browser on your computer, then click on “Calendar”.
2) Publicly share the calendar you want to export by clicking on the signal icon beside the calendar name, and click “Public Calendar”.
3) Select and copy the web address from the calendar that you want to export and paste it to your browser’s address bar. You should notice that it begins with the text, “webcal”. Replace “webcal” with “http” and then press Enter. This will initiate the download of your iCloud calendar as an iCal (.ics) file.
4) Your iCloud calendar should now be downloaded as an iCal (.ics) file. It should show up in your internet browser’s set Download’s folder.
You can import this file into Outlook. Once your data is in Outlook, you can use AkrutoSync to keep your data synced between Outlook and your devices (Android, Windows Phone, iOS (iPad/iPhone/iPod).
Now that you have your calendar in a .ical file on your computer, you can import your calendar into Outlook.
