An organization relationship lets users in your Exchange organization share calendar free/busy information with an Office 365 organization or with another Exchange on-premises organization. You can remove an organization relationship to disable calendar sharing with the other organization.

Before you can share calendars with another organization, you have to set up an authentication relationship with the Azure Active Directory authentication system (also known as “federation”) and must meet minimum software requirements. To learn more about federated sharing, see Sharing.

  • Estimated time to complete: 5 minutes.

  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the “Calendar and Sharing Permissions” section in the Recipients Permissions topic.

  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.

  1. On an Exchange 2013 server in your on-premises organization, navigate to organization > sharing.

  2. Under Organization Sharing, select an organization relationship, and then click Delete Delete icon to remove organization relationship.

  3. In the warning that appears, click yes.
