Administrators can disable it, but leaving the setting untouched means opting in.\n\nIn this instance, [Anthropic operates as a Microsoft subprocessor](https://learn.microsoft.com/en-us/copilot/implement/connect-to-ai-subprocessor), and Claude models are already on by default for most customers in the Windows giant's commercial cloud. The exceptions, notably, include the European Union, the European Free Trade Association, and the UK. \n\nHowever, UK tenants aren't in scope for Microsoft's EU Data Boundary - [launched at the start of 2023](https://www.theregister.com/security/2022/12/15/microsoft-launches-eu-data-boundary-from-next-year/1385411) - and so Redmond is flipping the switch for the country.\n\nAnthropic processes the relevant data in the United States, [Microsoft's documentation states](https://servicetrust.microsoft.com/ViewPage/DocumentPreview?documentId=37bec9fa-5bbd-450f-8178-1418411358ba). Administrators therefore have until December 9 to review whether that meets their organization's data-handling requirements and set access accordingly.\n\nMicrosoft is also retiring the setting that restricts Claude access to Microsoft 365 alone.\n\n\"This affirms Microsoft's commitment to offering choice between leading AI models while maintaining enterprise-grade security and compliance,\" the Redmond-based biz said.\n\nSo long as you don't mind processing happening in the US. ®\n\nGet AI news in your inbox\n\nDaily digest of what matters in AI.", "url": "https://wpnews.pro/news/microsoft-is-giving-claude-the-keys-to-uk-copilot-tenants-by-default", "canonical_source": "https://www.machinebrief.com/news/microsoft-is-giving-claude-the-keys-to-uk-copilot-tenants-by-5esr", "published_at": "2026-11-10 11:30:00+00:00", "updated_at": "2026-11-10 12:23:05.249766+00:00", "lang": "en", "topics": ["ai-products", "large-language-models", "ai-policy"], "entities": ["Microsoft", "Anthropic", "Claude", "Copilot", "Microsoft 365", "EU Data Boundary"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/microsoft-is-giving-claude-the-keys-to-uk-copilot-tenants-by-default", "markdown": "https://wpnews.pro/news/microsoft-is-giving-claude-the-keys-to-uk-copilot-tenants-by-default.md", "text": "https://wpnews.pro/news/microsoft-is-giving-claude-the-keys-to-uk-copilot-tenants-by-default.txt", "jsonld": "https://wpnews.pro/news/microsoft-is-giving-claude-the-keys-to-uk-copilot-tenants-by-default.jsonld"}}
