I’m excited to share a visualisation I created in the metaverse to help explain how Microsoft Graph and the Semantic Index work together across an organisation.

Microsoft Graph is the backbone that connects all your Microsoft 365 data—like emails, documents, meetings, and people—across your entire organization. It lets you access and manage information securely, respecting who can see what based on permissions and organizational boundaries.

The Semantic Index is a smart, AI-powered layer built on top of Microsoft Graph. It indexes and understands the meaning and relationships between all your data, making searches more accurate and contextually relevant. This index is created at both the tenant level (for the whole organization) and the user level (for each individual).

In my video, you’ll see:

• Green represents the data that can be accessed by a specific user.
• Blue shows data that the user cannot access.
• Red highlights common, shared data that the user can access, thanks to permissions and collaboration.

Together, Microsoft Graph and the Semantic Index ensure that every user gets personalized, relevant results while keeping your organization’s data secure and private.

I hope this visualization helps you see how Microsoft 365 Copilot leverages these technologies to give you a smarter, more connected experience!
