Summary:
Anthropic models will be enabled by default in many Microsoft 365 Copilot experiences starting January 7, 2026, with Anthropic onboarded as a Microsoft subprocessor under Microsoft’s data protection terms. Admins can opt out, and some regions (EU/EFTA, UK) and government clouds have exclusions or require opt-in.
Details:
Updated March 3, 2026: Rollout of Anthropic models in the Researcher agent is ongoing through March. We expect the deployment to reach full completion by the end of the month. During this phased rollout, the Anthropic option in Researcher may not yet be visible in all tenants; the existing Researcher functionality remains unchanged. We will provide another update in this post when rollout to Researcher is complete.
Use Claude with Researcher in Microsoft 365 Copilot
[Introduction:]
In September, Anthropic models became available in certain Copilot experiences through an opt-in setting, where use was subject to Anthropic's commercial terms and data processing agreement. On January 7, 2026, Anthropic models will be enabled by default for many customers and now offered under the Microsoft Product Terms and Data Protection Addendum. To enable this change, Anthropic has been onboarded as a Microsoft subprocessor. This transition extends Microsoft's contractual commitments and data protection standards to the use of Anthropic models in Copilot experiences.
