What's new in Microsoft 365 Copilot (June 2026)

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.

Word: Document summaries, personalised writing suggestions, and Claude now available in Copilot for Word.

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.

SharePoint: Custom skills, a live FAQ, and AI-generated charts for your sites.

Some features you can try this week:

Plan mode in Excel – Ask Copilot to reshape data and review its plan before it runs.

Notebooks – a deck - Gather notes (or a Teams meeting) and generate a PowerPoint from them.

Call delegation in Teams - Let Copilot pick up a call, capture context and suggest a follow-up.

Draft coaching in Outlook - Draft an email by chatting, and let Copilot coach the tone.

Researcher - Point it at a topic for a deeper, multi-source summary.

What’s coming next?

Worldwide rollout – Notebook generation, auto-infographics and Teams meetings as sources reaching everyone through June.

The new design for all – The refreshed app and OneNote sync arriving across the board.

More model choice – Broader choice of AI models across more Copilot surfaces.

Adoption support – A new Copilot Adoption Hub and guided rollout campaigns.

On the IT radar - Enterprise agent governance (Agent 365 / E7).

Copilot is moving beyond standalone features of the AI agent, into something more connected across your Microsoft environment. The focus has shifted for users to save time, reduce manual work and help teams make faster decisions.
