Copilot updates explained: Notebooks, Cowork and more

Most IT leaders are trying to keep AI moving while managing projects, risk, governance and support.

The question is simple: What are the latest Copilot updates, and what do they actually mean for your organisation?

 Here’s what has changed, why it matters now, and where IT leaders need to focus to stay in control.

Copilot is moving from a conversational assistant to a more agentic tool that carries out tasks, works across documents and uses persistent context. That means Copilot now depends far more on clean data, clear governance and strong SharePoint foundations.

Copilot Notebooks: a more focused way to create and explore

• New canvas-style workspace for deeper exploration and creation
• Notebook grounding keeps outputs tied to the content you add
• Improved collaboration so teams can build and review together 

• Handles long-running, multi-stage tasks across Microsoft 365
• Operates entirely in Microsoft's cloud for safer execution
• Success depends on well-structured SharePoint data and metadata

What this means for IT leaders

All the updates point in the same direction: Copilot is getting more capable, but also more dependent on the foundations it sits on. Clean data. Structured permissions. Reliable SharePoint and metadata. The technology is ready, the environment it runs in needs to be ready too.

We see this across many organisations. The benefits land quickly when the basics are in place, and accuracy slips when they are not. The real-world picture shapes our guidance. It's grounded in what works, what causes issues and what gives IT leaders confidence as Copilot becomes more agentic.

A practical next step is to review the areas Copilot relies on most: SharePoint structure, metadata, ownership and access. Tidying these new prevents issues later and helps Copilot behave consistently.
