Cross-premises communication or cloud-based co-existence is a deployment model in which part of a tenant organization's mailboxes are hosted and part of the organization mailboxes aren't hosted but exist in the organization's own Exchange 14 on-premises deployment.

Примечание.
Although this topic describes the steps that are required to correctly configure the organization for cross-premises communication, a Directory sync application that will automatically synchronize the organizations is required to fully implement this model.

If done correctly, users whose organization is configured in a cross-premises scenario shouldn't be able to detect that they aren't in the same Exchange organization.

Prerequisite

  • Create the tenant organization.
