Microsoft switches Claude on by default for UK Copilot tenants on 9 December

[QuietObserver34]

UK businesses using Microsoft 365 Copilot will soon have Anthropic's models switched on unless they say otherwise. The Register reports that from 9 December, Claude will be enabled by default for UK tenants whose admins have not already chosen a setting

Until now the UK was excluded, along with the EU and EFTA countries. The UK is not covered by Microsoft's EU Data Boundary, which is part of why the change applies there

Anthropic acts as a Microsoft subprocessor and processes the data in the US, according to Microsoft's documentation. Microsoft is also retiring the setting that limited Claude to Microsoft 365 only

Admins who do not want Claude need to turn it off in tenant settings before 9 December, because leaving the setting untouched counts as opting in. Microsoft said the move affirms its commitment to offering choice between leading AI models

More choice of models inside Copilot is useful, since different models suit different tasks. The opt out approach means IT teams should check their settings now rather than be surprised later. Organisations with strict data rules will want to review the US processing detail carefully

Will your organisation keep Claude switched on in Copilot? And should features like this be opt in rather than opt out?
