An organization relationship enables users in your Exchange organization to share calendar free/busy information as part of federated sharing with other federated Exchange organizations. In the course of normal operations, Exchange organizations may want to change several of the properties of an organization relationship, such as changing the name of the organization relationship, temporarily disabling calendar free/busy sharing with the external Exchange organization, changing the free/busy access level, or changing which security groups in your organization are enabled for calendar free/busy sharing.

To learn more about federated sharing, see Sharing.

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