Applies ToOutlook on the web

If you have Microsoft 365 or another email service based on Microsoft Exchange Online, use Outlook on the web to share your calendar with people inside or outside your organization. Depending on the permission you give them, they can view your calendar, edit it, or act as your delegate for meeting requests.

  • Calendar sharing may not be available for your account, or may be limited to people in your organization, depending on your organization settings.

  • For Outlook.com, see Share your calendar in Outlook.com.

If the instructions don't match what you see, you might be using an older version of Outlook on the web. Try the Instructions for classic Outlook on the web.

  1. At the bottom of the page, select Calendar to go to Calendar.

  2. In Calendar, on the toolbar at the top of the page, select Share, and choose the calendar you want to share.

    You can't share calendars owned by other people.

  3. Enter the name or email address of the person you want to share your calendar with.

  4. Choose how you want the person to use your calendar:

    • Can view when I'm busy lets them see when you're busy but doesn't include details like the event location.

    • Can view titles and locations lets them see when you're busy, as well as the title and location of events.

    • Can view all details lets them see all the details of your events.

    • Can edit lets them edit your calendar.

    • Delegate lets them edit your calendar and share it with others.

  5. Select Share. If you decide not to share your calendar right now, select Remove.

    • When sharing your calendar with someone who's not using Outlook on the web, for example, someone using Gmail, they'll only be able to accept the invitation using a Microsoft 365 or an Outlook.com account.

    • ICS calendars are read-only, so even if you grant edit access to other people, they won't be able to edit your calendar.

    • How often your ICS calendar syncs depends on the email provider of the person you've shared it with.

    • Calendar items marked private are protected. Most people you share your calendar with see only the time of items marked private, not the title, location, or other details. Recurring series marked as private will also show the recurrence pattern.

You can change the permissions you’ve set for a calendar, or stop sharing the calendar completely, by right-clicking the calendar name under Calendars.

Alternatively, recipients can use the ICS link to subscribe to your calendar through Outlook. They'll see your calendar alongside their own and will automatically receive any updates to your calendar.
