Microsoft 365 Copilot Gets a Major Redesign: Faster, Cleaner, and Actually Useful
Microsoft has redesigned the Microsoft 365 Copilot experience across all M365 apps, with faster load times, smarter context, and a cleaner interface.
Microsoft rolled out a significant redesign of Microsoft 365 Copilot on May 28, 2026, affecting how Copilot looks and behaves across Word, Excel, PowerPoint, Outlook, Teams, and the Copilot app itself. The changes are available now for Current Channel (Preview) users, with full rollout to all Current Channel subscribers expected by mid-June 2026.
This is not a cosmetic refresh. Microsoft has rethought the fundamental interaction model, and the usage numbers already back it up: after rolling out the new in-app experiences internally, Copilot usage increased by 27% in Word, 33% in Excel, 43% in PowerPoint, and 30% in Outlook.
What’s Actually Changed
A Unified Entry Point Across Every App
Previously, Copilot appeared in different ways depending on which app you were in. The redesign introduces a single, consistent entry point that sits above your work and understands the context of what’s beneath it. Rather than hunting for the right button or panel, Copilot is now anchored as one connected system across Microsoft 365.
From that entry point, Copilot opens a side pane that works directly with your document, not just as a chat window, but as an editing partner that can suggest or make changes. You can also invoke Copilot directly on the canvas itself, within a paragraph, a cell, or a slide, so the interaction starts where your work already lives.
The Prompt Box Has Grown Up
The old static text box has been replaced with a task-aware workspace. The redesigned prompt box is larger, supports richer formatting, and handles longer input without feeling cramped. Below it, Copilot surfaces tools and controls relevant to what you’re trying to do, rather than presenting a generic interface regardless of context.
Responses are now delivered in structured, layered chunks. You get a concise summary first, then formatted tables, suggested follow-ups, and action shortcuts appear as you continue refining your request. This is a noticeable improvement over the previous approach of receiving one long block of output.
Work IQ: The Context Layer You Actually Control
Powering the smarter behaviour under the hood is Work IQ, an intelligence layer that draws on your emails, files, chats, and calendar to build a contextual understanding of how you and your organisation actually work. Crucially, you can see when it’s active and control it directly. It adapts between quick responses for simple tasks and deeper reasoning for complex ones, including the ability to choose which AI model handles a given request.
Load Times Are More Than Twice as Fast
Microsoft measured load time improvements using User Perceived Load Time across a test group of approximately 11 million users. The result: load times reduced by over 50%. For a tool people open dozens of times a day, this matters more than most feature additions.
App-Specific Improvements Worth Knowing
PowerPoint: The Designer feature and Copilot now work together. Copilot handles the content structure; Designer immediately proposes matching slide layouts. You get AI-generated text and visually polished slides at the same time.
Teams: A new “Meeting Prep” prompt pulls together the meeting invite, related chat history, and shared files, then pre-fills a Copilot chat with suggested questions. This is genuinely useful for anyone who has ever joined a meeting underprepared.
Mobile: The Microsoft 365 Copilot mobile app has been rebuilt with a chat-first design, cleaner navigation, text formatting in prompts, and a new liquid glass visual style. Citations are easier to access and reopen, and there is now a dedicated visualisation for voice conversations.
What This Means for You
If you use Microsoft 365 Copilot regularly, you will notice the difference immediately. The experience is faster, less cluttered, and considerably better at understanding what you are actually trying to accomplish rather than waiting for you to phrase a perfect prompt.
For IT administrators, the redesign reduces user friction, which should lower support volume. The rollout respects your existing controls: Group Policy and the Microsoft 365 Apps admin center give you the same governance tools you already use. Semi-Annual Enterprise Channel customers will see the changes in the July 2026 update, and admins can pause feature updates through existing channels if needed.
For small businesses, there is additional context worth noting. From July 1, Microsoft is introducing new SKUs, Microsoft 365 Business Standard with Copilot and Microsoft 365 Business Premium with Copilot, that bundle these capabilities directly into the subscription rather than requiring a separate Copilot add-on licence.
Under the Hood: New Models and Connections
The redesign also brings meaningful additions to what Copilot can actually do:
- Model selection is now built into the interface. You can choose between available models depending on the task.
- Anthropic’s Claude Opus 4.8 is now available inside Microsoft 365 Copilot, suited for complex, multi-step tasks and long-running workflows.
- OpenAI’s GPT-5.5 Instant is also available, focused on clearer, more concise answers for everyday work.
- Federated MCP Connectors allow Copilot to query partner systems live at prompt time using the Model Context Protocol, so answers reflect current data rather than stale snapshots. Supported partners include Canva, HubSpot, Linear, Moody’s, and Notion. Access follows the user’s existing identity and permissions.
- Apple CarPlay support has been added, giving users a hands-free way to continue Copilot conversations while driving.
The Honest Context
It is worth acknowledging that Microsoft has had some stumbles getting Copilot’s interface right. The company previously admitted the floating Copilot button added to Word, Excel, and PowerPoint was a mistake, and has since moved it to a less intrusive permanent icon at the bottom right of the screen. This redesign reflects that feedback. The goal is clearly to make Copilot feel like a capable colleague working alongside you rather than a feature constantly trying to get your attention.
The full announcement from Microsoft is worth reading if you want the detailed breakdown. For most people, though, the update will simply arrive as part of your next monthly Office update and speak for itself.
