Import or subscribe to a calendar in outlook on the web

Note: You're using Outlook on the web if you use a work or school account to sign in to Microsoft 365. To get instructions for importing or subscribing to a calendar in an Outlook.com, Hotmail, Live, or MSN account, see Import or subscribe to a calendar in Outlook.com.

In Outlook on the web, you can import events from an .ics file to your existing calendar or subscribe to a calendar online and receive automatic updates (known as an ICS subscription or an iCal subscription). You can import calendars from websites or calendar programs that support the .ics file format, such as Apple iCal, Google Calendar, and Mozilla Lightning.

You can search the internet for lists of iCals. Websites for theaters, sports teams, and schools often have an "Add to calendar" link that you can use to download an iCal. Bing also has suggestions for calendars.

For more information about adding calendars, see Add a calendar in Outlook.com or Outlook on the web.

Note: Microsoft isn't responsible for the accuracy or content of any third-party calendars. We recommend that you review the terms and conditions before importing or subscribing to any third-party calendars.

The difference between importing and subscribing

When you import an .ics file, you get a snapshot of the events in the calendar at the time of import. Your calendar doesn't refresh the imported events automatically -- even if the calendar's owner makes an update. This is a good way to add events that aren't going to change to your existing calendar, like tide tables, or phases of the moon.

Subscribing to an iCal online calendar connects it to your calendar. Whenever the owner of an iCal you've subscribed to makes changes to the events, Outlook on the web updates your calendar. This is a good way to track events that change frequently, like movie times or a school calendar.

Note: This update can take more than 24 hours.
