View and subscribe to Internet Calendars

Internet Calendars are calendars that are shared through the Internet. These calendars are based upon a global Internet standard that allows calendar information to be exchanged between people regardless of the application that is used to create or view the information. Internet Calendars use the iCalendar format and the .ics file name extension.

There are two types of Internet Calendars — Calendar Snapshots and Internet Calendar Subscriptions.

View a Calendar Snapshot

A Calendar Snapshot is sent to you in an e-mail message in the iCalendar format. It is a static calendar that can be updated only after the calendar owner sends you a new Calendar Snapshot. There are two ways in which you can view the calendar information in a Calendar Snapshot — in the message body or as an additional calendar in Calendar view in Outlook.

 Tip    See Send an Outlook 2010 calendar in an email message to learn how to send a Calendar Snapshot.

Add an Internet Calendar Subscription to Outlook

An Internet Calendar Subscription is a calendar that you download and view in Outlook. However, unlike a Calendar Snapshot, Internet Calendar Subscriptions are updated automatically.

These calendars can be found on Web sites where people host calendars. On such a Web site, you can click a link to download and subscribe to the calendar, or someone can send you a link to the Internet Calendar Subscription in an e-mail message. This link is an Internet Web address that begins with webcal://, instead of http://, and ends with a file name that has the .ics file extension.

  1. Click the link for the Internet Calendar Subscription.

You might be prompted to acknowledge that you are opening a hyperlink. You should click Yes only if you know and trust the validity of the linked calendar.

  1. At the prompt, Add this Internet Calendar to Outlook and subscribe to updates, click Yes.

The Internet Calendar opens in side-by-side view in the Outlook Calendar and is added to the Navigation Pane in Calendar view under Other Calendars. The calendar will check periodically for any updates made by the calendar publisher.
