Modify an organization relationship

  • Article

Applies to: Exchange Server 2013

An organization relationship lets users in your Exchange organization share calendar free/busy information with a Microsoft 365 or Office 365 organization or another on-premises Exchange organization. You may want to change the settings of an organization relationship, such as changing the name, temporarily disabling calendar sharing, changing the access level, or changing which security groups will share calendars.

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

For additional management tasks related to federation, see Federation procedures.

What do you need to know before you begin?

  • Estimated time to complete: 15 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 entry in the Recipients Permissions topic.

  • An active federation trust for the on-premises Exchange organization must be configured.

  • The external organization you want to configure in the organization relationship must also have a federation trust established with the Microsoft Entra authentication system.

  • The procedures in this topic make changes to an organization relationship named Contoso. The examples show how to:

    • Add a domain named service.contoso.com to the external organization.
    • Disable free/busy sharing for the organization relationship.
    • Change the free/busy access level from Calendar free/busy information with time, subject, and location to Calendar free/busy information with time only.

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