In this video we show you how to find the calendar link for an Outlook.com calendar (formerly Hotmail). For Outlook 365, see Outlook 365 calendar
In order to share an Outlook.com calendar outside the platform, one needs to publish it. This means your data is not as secure. We recommend that you change to a Google or Yahoo! calendar as your standard. This problem is the same as for iCloud calendars and you can learn more about this here: iCloud calender (and why it should be your default calendar)
