When B2B direct connect is established between two organizations, users in one organization can create a shared channel in Teams and invite an external B2B direct connect user to it. When the trust is established, the B2B direct connect user has single sign-on access to resources outside their organization using credentials from their home Azure AD organization.Ĭurrently, B2B direct connect capabilities work with Teams shared channels. Both the resource organization and the external organization need to mutually enable B2B direct connect in their cross-tenant access settings. Or use it to share resources across multiple Azure AD tenants within your own organization.ī2B direct connect requires a mutual trust relationship between two Azure AD organizations to allow access to each other's resources. Use B2B direct connect to share resources with external Azure AD organizations. With B2B direct connect, users from both organizations can work together using their home credentials and a shared channel in Teams, without having to be added to each other’s organizations as guests.

This feature currently works with Microsoft Teams shared channels. Azure Active Directory (Azure AD) B2B direct connect is a feature of External Identities that lets you set up a mutual trust relationship with another Azure AD organization for seamless collaboration.
