Microsoft announced on November 5, 2026, that Claude processing in Copilot is planned to move inside the EU Data Boundary for organizations in the European Union and European Free Trade Association by the end of 2026. The plan names no US-specific rollout. Microsoft’s announcement sets a future target, not a completed migration.
What Microsoft plans for Claude in Copilot
The planned change covers Claude models across Copilot experiences, including Copilot Chat, Copilot in Microsoft 365 apps, Copilot Cowork, and Copilot Code. Microsoft says organizations in the EU and EFTA already using Claude will transition automatically once the processing change is available.
For an EU or EFTA organization, enabling Claude access and moving its processing within the regional boundary are separate steps.
Enabling Claude is a separate admin action
Claude is off by default in the EU and EFTA. Administrators can enable it for everyone or assign access to selected users and groups. Microsoft Learn’s page, last updated November 4, 2026, described Claude as outside the EU Data Boundary at that time and documents the access controls: an AI Administrator or Global Administrator enables Anthropic in the Microsoft 365 admin center, then assigns access to users or groups. The path is Copilot > Settings > View all > AI providers operating as Microsoft subprocessors. Microsoft Learn’s admin documentation describes access setup; Microsoft’s later announcement says processing for existing users will transition automatically when the planned change becomes available.
EU-wide processing is different from in-country residency
The EU Data Boundary is a regional commitment: Microsoft says it covers storing and processing Microsoft 365 and other online-services data within the EU and EFTA. Separately, Microsoft offers in-country data residency for Microsoft 365 data at rest in 10 EU and EFTA countries. That option concerns storage within an individual country, while the announced Claude processing change is scoped to the EU and EFTA as a region.
