Microsoft Entra: Cross-tenant security group synchronization

We’re introducing cross-tenant group synchronization, a new capability that enables organizations to synchronize security groups across Microsoft Entra tenants. This feature simplifies collaboration scenarios by allowing shared access to resources across tenants while maintaining centralized group management. It also streamlines administration of multiple tenants by centralizing group membership control, reducing duplication and manual overhead.
