Claude is now available via Copilot: June 2026 Microsoft 365 Updates
Updates, improvements and what to try
Microsoft 365 Copilot continues to make improvements. June’s updates focus on speed and deeper integration across the tools your team already uses.
With one of the biggest updates including access to Claude within Copilot.
50% faster responses across Copilots models, 2x quicker to load - the app opens in half the time.
As the experience improves, usage is naturally becoming part of everyday workflows rather than one-off tasks.
What’s new this month?
Claude available in Copilot: For users holding a Microsoft 365 license, access to Claude is now included, giving users more flexibility in generating content via AI, in one platform.
Refreshed app: a cleaner look with a chat first design, accompanied by a smart prompt line allowing a better view of the right tools, as you type.
More model choices: Claude Opus 4.8 for deep work and Chat GPT-5.5 Instant, for fast replies with the choice to pick between Quick or Think Deep.
Copilot notebooks: A tool to help you manage your notes more effectively, organising projects and generating decks, documents and spreadsheets more seamlessly.
Live data connectors: Real-time information can be pulled from tools and apps like HubSpot, Notion and Canva, just within a few clicks.
Improved integration across Microsoft 365
Excel: Plan Mode previews every change before it touches your workbook; Python for advanced analysis.
Teams: Call delegation answers calls you can't take, captures context and offers a follow-up. Plus video recaps.

PowerPoint: Slide explanations, an executive-summary slide, and built-in skills to speed up decks.
Outlook: Account selector in the side pane, draft coaching and conversational email drafting.

What’s coming next?
Worldwide rollout – Notebook generation, auto-infographics and Teams meetings as sources reaching everyone through June.
