Internet Calendars are calendars that you publish to an Internet site, where others can view it or subscribe to it. Internet Calendars use the iCalendar format and the .ics file name extension.

You can share one-time static calendars, known as Calendar Snapshots, in an email message. Or you can publish calendars to a special web server designed to host calendars in the iCalendar format. The benefit of the latter is that when you change the calendar in Outlook, the changes are synchronized to the web server. This enables those who use an Internet Calendar subscription to see the latest information automatically.

Tip: See Create additional calendars to add new calendars.

Why publish Internet Calendars?

Internet Calendars let you share calendar and availability information with other people. For example, you can publish your soccer team's practice schedule. Each player can subscribe to the published calendar and then see any updates that you make to the calendar. Other people might choose to view the Internet Calendar subscription in a web browser, Outlook, or another application.

How to publish Internet Calendars

You can share your Outlook calendar with others by publishing it from Outlook on the web.

To share your Outlook calendar on, first save it as an iCalendar (.ics file), import it into, then share it with the people who need to see it.

Under the settings in Outlook on the web, go to Calendar > Shared calendars. Choose the calendar you wish to publish and the level of details that you want others to see.

Note: Published calendars are viewable by anyone with the link to the calendar.
