+
+# Copilot in Microsoft 365 apps with Anthropic models
+
+To provide additional flexibility in model choice for customers in the European Union (EU), European Free Trade Association (EFTA), and United Kingdom (UK), Microsoft 365 Copilot includes an admin setting that enables the use of Anthropic models in Copilot experiences across Word, Excel, and PowerPoint.
+
+This setting allows Microsoft 365 Copilot in supported Microsoft 365 apps to use Anthropic models by default when generating or refining content.
+
+## Anthropic model availability in Microsoft 365 apps
+
+As the admin, you can manage the Anthropic model setting in the Microsoft 365 admin center. When this setting is turned on, Anthropic models are available for use in Copilot experiences across:
+
+- Microsoft Excel  
+- Microsoft PowerPoint  
+- Microsoft Word *(support for Anthropic models will be added in summer, 2026)*
+
+This setting applies only to Copilot experiences within these apps and does not affect Anthropic model usage in other Microsoft 365 Copilot features or services. It is separate from the [global Anthropic subprocessor setting in Microsoft 365](connect-to-ai-subprocessor.md). Changes to this setting do not modify global subprocessor configurations.
+
+This setting is on by default for tenants in the EU, EFTA, and UK that were created after March 25, 2026. For tenants in the EU, EFTA and UK that existed before March 25, 2026, check the [Message Center](https://go.microsoft.com/fwlink/p/?linkid=2070717) for details on your tenant’s default setting.
+
+All tenant administrators are encouraged to check their tenant’s setting to make sure it aligns with their company's requirements.
+
+## Data processing and the EU Data Boundary
+
+When Anthropic models are used in Copilot experiences in Word, Excel, or PowerPoint, data processing for these models occurs outside of the Microsoft EU Data Boundary (EUDB).
+
+[Anthropic operates as a Microsoft subprocessor](connect-to-ai-subprocessor.md) and is subject to Microsoft Product Terms and the Microsoft Data Protection Addendum (DPA).
+
+## Manage the setting in the Microsoft 365 admin center
+
+1. Sign in to the Microsoft 365 admin center as an administrator assigned the **AI Administrator** role.  
+2. Go to **Copilot** -> **Settings** -> **View All** -> **AI providers operating as Microsoft subprocessors**.
+
+    :::image type="content" source="media/ai-providers-operating-as-subprocessors.png" alt-text="Screenshot  of the AI providers operating as Microsoft subprocessors page with All users selected" lightbox="media/ai-providers-operating-as-subprocessors.png":::
+
+3. Confirm the correct setting for your organization.
+
+> [!NOTE]
+> Support for Anthropic models in Microsoft 365 apps varies based on how the AI providers operating as Microsoft subprocessors setting is scoped in your organization. When the setting is enabled for **All users**, Anthropic model use in supported apps is unavailable and can't be changed. When the setting is scoped to **No users**, Enterprise, public sector, and EDU tenants have Anthropic model use in apps turned off by default but can enable it, while non‑Enterprise tenants have Anthropic model use turned on by default but can disable it. This allows admins to control whether Anthropic model processing can be flexibly routed within the EU. This setting applies only to Copilot experiences within supported apps and doesn't affect Anthropic model usage in other Microsoft 365 Copilot features or services. For more information, see [Flex routing (EU and EFTA)](/copilot/microsoft-365/copilot-flex-routing).

+
+# Flex routing (EU and EFTA)
+
+Flex routing lets customers in the European Union (EU) and the European Free Trade Association (EFTA) allow large language model (LLM) inferencing to occur outside the EU Data Boundary during periods of peak demand to help maintain a consistent Copilot experience. Inferencing is the processing step when an AI model executes the prompt to produce an output or response, such as summarizing content or answering a question.
+
+No matter where LLM inferencing occurs, data will be encrypted in transit and at rest. Data at rest will continue to be stored inside the EU Data Boundary, except for limited pseudonymized data which may be stored outside the EU Data Boundary for security and operational purposes. For more information, see [Ongoing partial data transfers](/privacy/eudb/eu-data-boundary-ongoing-partial-transfers).
+
+Tenant administrators can change the flex routing setting at any time in the Microsoft 365 admin center or Power Platform admin center. The Microsoft 365 admin center setting applies to Microsoft 365 Copilot and Copilot Chat. The Power Platform admin center setting applies to Copilot experiences in Dynamics 365, Power Platform, and Copilot Studio.
+
+> [!NOTE]
+> By default, the flex routing setting in the Power Platform admin center will be the same as the setting in the Microsoft 365 admin center unless you choose a more restrictive setting in the Power Platform admin center. For more information, see [Move data across regions for Copilots, AI agents, and generative AI features](/power-platform/admin/geographical-availability-copilot).
+
+## Eligibility
+
+Flex routing is available for customers with a sign-up location in a country or region in the EU or EFTA. For more information, see [EU Data Boundary countries and datacenter locations](https://learn.microsoft.com/privacy/eudb/eu-data-boundary-learn#eu-data-boundary-countries-and-datacenter-locations).
+
+Note that this setting will not be available for customers who have purchased multi-geo capabilities even if their tenant is listed as being in a country or region in the EU or EFTA. Customers can check their tenant’s country or region in the [Microsoft 365 admin center](https://learn.microsoft.com/microsoft-365/admin/manage/change-address-contact-and-more).
+
+## Set up flex routing
+
+Flex routing is on by default for eligible tenants that were created after March 25, 2026. For eligible tenants that existed before March 25, 2026, please check the Message Center for more details on your tenant’s default flex routing setting.
+
+All tenant administrators are encouraged to check their tenant's flex routing setting to ensure it aligns with their company's requirements.
+
+**Enable flex routing**
+
+1. Sign in to the Microsoft 365 admin center as an administrator assigned the [AI Administrator role](/entra/identity/role-based-access-control/permissions-reference).
+2. Go to **Copilot** -> **Settings** -> **Flexible inferencing during peak load periods**.
+3. Select **Allow flex routing during periods of peak load**.
+    1. This setting allows LLM inferencing and the storage of associated pseudonymized data to occur outside the EU data boundary during periods of peak demand. Typically, these periods are limited in duration and do not run continuously.
+4. If you don’t want to allow flex routing, select **Do not allow flex routing**.
+    1. If you select this option, LLM inferencing will occur inside the EU Data Boundary, even during periods of peak demand. All Microsoft 365 data processing and data residency commitments will continue to apply.
+
+## Frequently asked questions
+
+### Why can't I see the flex routing setting in the Microsoft 365 admin center?
+
+The flex routing setting is only visible in the Microsoft 365 admin center for customers with a sign-up location in a country or region in the EU or EFTA.
+For more information, see [EU Data Boundary countries and datacenter locations](https://learn.microsoft.com/privacy/eudb/eu-data-boundary-learn#eu-data-boundary-countries-and-datacenter-locations). This setting is also not available for customers who have purchased multi-geo capabilities even if their tenant is listed as being in a country or region in the EU or EFTA. Customers can check their tenant’s country or region in the [Microsoft 365 admin center](https://learn.microsoft.com/microsoft-365/admin/manage/change-address-contact-and-more).
+
+### How does flex routing affect Microsoft’s EU data boundary commitments?
+
+When flex routing is enabled, LLM inferencing may occur outside the EU Data Boundary during times of peak demand. Data remains encrypted in transit and at rest. Data will also continue to be stored at rest inside the EU Data Boundary except for limited pseudonymized data which may be stored outside the EU Data Boundary for security and operational purposes. For more information, see [Ongoing partial data transfers](/privacy/eudb/eu-data-boundary-ongoing-partial-transfers). EU and EFTA customers can disable flex routing in the Microsoft 365 admin center at any time.
+
+### Where does LLM inferencing occur when flex routing is enabled?
+
+If flex routing is enabled, LLM inferencing may occur in the United States, Canada, or Australia during times of peak demand.
+
+### Why can't I change the flex routing setting in the Power Platform admin center?
+
+If flex routing is not allowed in the Microsoft 365 admin center, flex routing will be off by default in the Power Platform admin center and you will not be able to change the setting. If flex routing is allowed in the Microsoft 365 admin center, then the flex routing setting in the Power Platform admin center will be configurable.
