If you want to share a calendar with someone who works for the same organization, the process is quite simple. Open the calendar in Outlook and then click Home > Share Calendar > Calendar.

If you’re using Outlook for more than one account, make sure you select the calendar for the account you want to share.

The “Calendar Properties” window will open on the “Permissions” tab, showing you who currently has access to your calendar. By default, Outlook is set up so that anyone in your organization will be able to see when you’re busy, but nothing else. Your IT people may have changed this in several different ways, so we’ll focus on sharing your calendar with an individual in your organization.

To share your calendar with someone, click the “Add” button.

This will open up your address book and by default show the people in your organization. Add the person you want to share your calendar with and then click “OK.”

The person you’ve chosen appears in Permissions window. By default, they’ll have a permission level of “Can view all details,” which you can change if you want.

When you’re done, click “OK” to share your calendar.

To view a calendar that someone has shared with you, click Home > Add Calendar > Open Shared Calendar.

In the window that opens enter the name of the person who has shared a calendar with you and then click OK.

The calendar will now appear for you to view under the “Shared Calendars” list on the left side.
