Microsoft adds Anthropic Claude model to 365 Copilot tools
Microsoft has integrated Anthropic's Claude Opus 4.7 model into Microsoft 365 Copilot. It appears in Copilot Cowork, early releases of Copilot Studio, and Copilot in Excel. The update promises faster responses and better handling of precise instructions and tool selection. Microsoft 365 E7 is now generally available. This bundle includes E5 features plus Copilot and Agent 365. Copilot Studio's 2026 wave 1 release plan has also been published.
Copilot users often stuck with OpenAI models that felt less sharp than standalone Claude or ChatGPT for complex tasks like data analysis or instruction-heavy prompts. Outputs came across as generic or unreliable, pushing people to external tools despite governance risks and company mandates to use M365. Claude Opus 4.7 brings top-tier precision directly into Copilot apps like Excel, keeping data secure within Microsoft's ecosystem. This cuts the temptation to copy-paste into ChatGPT, while addressing low adoption by matching rivals' quality without leaving Teams or Outlook.

Ditch tool paralysis: today in Excel, switch to Claude Opus 4.7 on your next dataset, prompt for a trend analysis summary, and demo the output in your next team huddle to spike adoption.
