Message ID: MC1031090
As part of our Secure by Default initiative, the tenant isolation feature will be enabled by default for all Power Platform tenants as the new default behavior. The enforcement is scheduled to begin in May 2025.
This feature applies only to Power Platform policies and is separate from guest access policies and Azure tenant restriction features.
How does this affect me?
Tenant isolation only applies to connectors running within a tenant. The default tenant isolation behavior will block all connection attempts from one tenant to another; inbound (connections to the tenant from external tenants), outbound (connections from the tenant to external tenants), or both (inbound – outbound) will be blocked by Power Platform.
Communications within the same tenant will not be affected. In addition, users logging in as guests (guest user access) will remain unaffected.
To prevent any disruptions, if our traffic monitoring logs indicate cross-tenant connections involving your tenant, we will proactively set up the necessary policies for you before the enforcement.
What do I need to do to prepare?
This message is for awareness and no action is required.

The upcoming enforcement of tenant isolation in Power Platform is an important step in enhancing security, and it promises to have significant implications for both admins and users. Starting in May 2025, this initiative will ensure that connections between different tenants are effectively blocked, which means that any data or resources shared across tenants will be safeguarded like a well-guarded secret.
For administrators, this change means a little less stress when it comes to managing external connections. With the default tenant isolation in place, they can rest assured that their tenant’s data will be protected from unexpected external access. However, it does mean that admins will need to be more vigilant about monitoring any cross-tenant connections that might have been set up previously. If they notice any such connections, they’ll need to prepare to adjust their policies accordingly—though the proactive measures taken by the Power Platform team will help ease this transition.
Users, on the other hand, will likely appreciate the enhanced security that tenant isolation brings. They can continue to collaborate within their own tenant without worrying about any unwanted intrusions from others. Plus, guest users will still be able to access the system just as they did before, which is a relief for those who regularly work with external partners.
Overall, the impact of these changes will be significant, but they are designed to enhance security and protect user data. While there might be a few bumps along the way as everyone adjusts, the end result should be a more secure and streamlined environment for all users.
