🧵 1/ Granular toggle for enabling Anthropic AI in Copilot coming soon. MC1263276, rolling out late April 2026. If you run Copilot or manage anyone who does, this one matters.

2/ TL;DR: Admins will soon be able to assign Anthropic (Claude) access in M365 Copilot to specific users or Entra ID groups. No more all-or-nothing tenant toggle.

3/ Why it matters: Claude powers some of Copilot's best stuff — Researcher, Agent Mode in Excel, Office agents, Copilot Studio. But processing happens outside Microsoft's data boundary.

4/ Excluded from the EU Data Boundary. Excluded from in-country commitments for the UK, Australia, India, Japan etc. EU/EFTA and UK tenants have it off by default for exactly this reason.

5/ Until now you had to choose: accept that for every user in the tenant, or turn Anthropic off and lose the features entirely. Not exactly a fun conversation with a compliance team.

6/ From late April you can scope it. Specific users, Entra ID groups, up to 999, nested groups supported. Enforced across Admin Center, PPAC, and Copilot Studio.
