Seamless M365 Inter-Tenant Collaboration with Entra ID

 

Expanding Collaboration Beyond Tenant Boundaries

In today's fast-evolving business landscape, organizations are seeking solutions to enhance collaboration and communication across different segments of their operations. Microsoft's introduction of Entra ID multi-tenant organization capabilities marks a significant advancement in this direction.

This platform facilitates seamless integration and collaboration across various tenants, ensuring that enterprises undergoing transformations such as mergers, acquisitions, or internal restructuring can maintain effective and streamlined operations. By leveraging features like B2B collaboration, cross-tenant access settings, and cross-tenant synchronization, businesses can ensure their employees have the necessary access to collaborate effectively. Furthermore, the general availability of unified chat in Microsoft Teams and engaging community experiences in Viva Engage, powered by Entra ID multi-tenant organization capabilities, exemplifies Microsoft's commitment to enhancing workplace collaboration and efficiency.

In this example, we’ll follow Contoso EMEA and Contoso APAC, two divisions of Contoso Conglomerate. Employees from Contoso EMEA and APAC are already using Microsoft Entra to share apps across tenants. Now they need to communicate across tenants using Microsoft Teams and Viva Engage. Leaders in the organization need to share announcements and storylines across the organization and employees need to chat using Teams. Let’s look at how the admins at Contoso configure their multi-tenant organization to meet these needs.

• The tenant administrators of Contoso EMEA and Contoso APAC agree to form an Entra ID multi-tenant organization, facilitated by an invite-and-accept flow between them.
• Microsoft Teams and Viva Engage applications in Contoso EMEA (APAC) will now interpret any external member users of identity provider Contoso APAC (EMEA) as employees of the multi-tenant organization with corresponding improved collaboration experience.

Simplifying the licensing model to require just one Entra ID P1 license per employee, per organization enhances its attractiveness by making it more cost-effective and straightforward for companies to adopt and implement.
