Power Platform – Tenant Isolation will be enabled by default across your tenant
Starting March 2025, Tenant Isolation will be enabled by default on your tenant to comply with the Secure by Default initiative. This default behavior will block all connection attempts from external tenants - inbound, outbound, or both - in Power Platform policies. However, communications within the same tenant will remain unaffected. To prepare for this change, you can establish an allow list of relevant tenant IDs and enable a tenant isolation policy before its enforcement. Note that this initiative is separate from guest access policy and Azure tenant restriction features. Stay ahead of the game by following the recommended guidelines to accommodate scenarios currently using cross-tenant connections.
