Microsoft will switch on Claude models in Microsoft 365 Copilot for every UK organisation whose admin has not picked a setting, unless the admin changes it first.

Hype check
Quieter than it deserves. This one matters more than the coverage suggests.

Your call: hype or real?
Real = it will matter in daily use. Hype = louder than it is. One vote, and it can’t be changed.
Our view and readers’ views are opinions, not statements of fact about a product.
Why it matters
Anyone who manages work accounts in the UK should check the setting first, because Claude data is processed outside the EU Data Boundary.
Watch: Microsoft keeps adding models from other companies to Copilot.
The details
- On December 9 Microsoft turns on Claude for every UK organisation whose admin has not set a choice.
- To turn it off or limit it to some users or groups, an admin must choose before December 9. Only AI admins and global admins can change it.
- Claude sits outside Microsoft's EU Data Boundary and is not yet available in Researcher, Copilot Studio or Power Platform.
- Microsoft is removing the option to allow Claude only inside Microsoft 365 apps; organisations with no choice move to "all users".
- In the EU nothing changes: Claude stays off until an admin enables it.
