Microsoft 365 Copilot Enables Claude AI for UK Tenants December 9

Microsoft 365 Copilot Adds Claude AI for UK Organizations

Microsoft will activate Anthropic’s Claude models within Microsoft 365 Copilot by default for UK tenants starting December 9. The change applies to organizations using Microsoft 365 Copilot in the United Kingdom, while tenants in the European Union will remain opted out because Claude is currently excluded from the EU Data Boundary.

What Changes for UK Administrators

UK administrators will find the new Claude integration enabled automatically. The setting can be managed in the Microsoft 365 admin center under the Copilot configuration section. Organizations that prefer not to use Claude can disable the feature through the same interface.

Claude Models Requiring Separate Opt-In

While the base Claude integration becomes active by default, certain advanced Claude models still require a separate opt-in process. Administrators should review the specific model availability and licensing requirements before enabling additional capabilities.

EU Data Boundary Compliance

The EU Data Boundary commitment means Microsoft stores and processes European customer data within the EU. Since Anthropic’s Claude does not yet meet this requirement, EU tenants are excluded from the automatic rollout. Microsoft has not announced a timeline for Claude availability in the EU.

This update reflects Microsoft’s strategy of offering multiple AI model choices within Copilot, allowing organizations to select the model that best fits their needs and regulatory constraints.
