Microsoft 365 Copilot now bundles Anthropic's Claude alongside OpenAI. For European customers one detail matters most: the Claude integration is off by default in the EU, EFTA and UK, and switching it on moves requests outside the EU Data Boundary. Inference runs on Anthropic's US infrastructure whichever Azure region you pick.Any DPIA that treats Microsoft 365 as one US-provider exposure is wrong from the moment an administrator opts in.Adoption can still make sense. Scope enablement to named Entra groups and refresh the DPIA; sensitive casework belongs on a separate stack.https://altlibre.com/blog/microsoft-anthropic-bundle-europe#DigitalSovereignty #GDPR #AI #InfoSec
