M365 Copilot Enterprise Commitments Extended to Anthropic Models

Back in September 2025, Microsoft announces that Anthropic models would be available to both M365 Copilot and Copilot Studio.  It was initially configured to be off by default and customers had to turn it on.

This has now changed.  Anthropic models are now covered under the Microsoft enterprise grade compliance and data handling commitments.  Thus, Anthropic models are now available by default to customers moving forward.  Customers still can disable access to Anthropic models should they choose to.  Please review the following references.
