5.2. Organizing and Sharing with Notebooks
💡 First Principle: A single chat is a conversation, while a notebook is a project. Copilot Notebooks gather the chats, files and outputs that belong together, and ground Copilot on that collection. So every new question you ask inside the notebook starts from the project's material rather than from a blank page.
Scattered chats cost you twice: once when you can't find the right one, and again when Copilot answers without the context you gathered last week. Notebooks fix both. They are persistent AI workspaces that keep related chats, outputs and references together, and they ground Copilot on the notebook's references, so answers inside a notebook draw on the material you put there. A notebook can also carry its own custom instructions.
What you can add to a notebook:
| Reference type | Available to |
|---|---|
| PDF, Word, Excel and PowerPoint files, Copilot Pages, images, audio, URLs | All users with Notebooks |
| Teams content, SharePoint and OneDrive files, internal URLs | Licensed users only (Microsoft Copilot (formerly Microsoft 365 Copilot) license) |
Since August 2026 you can also add Outlook emails and Teams meetings as notebook references.
Organizing chats into a notebook: open the chat's … More menu and select Move to notebook, then choose the notebook. The chat now lives with the rest of that project's material.
Sharing a notebook: select Share (upper right) > enter names or email addresses > Invite. Recipients are automatically invited to linked files if you have sharing permission on them. The sharing rules are strict and frequently tested:
| Rule | What it means |
|---|---|
| Edit access only | Everyone you invite can edit; there's no read-only option |
| No groups | You invite individuals; a group can't be a member |
| No external sharing | Only people inside your organization |
| Work accounts only | Not available for Personal, Family, Premium or Pro consumer subscriptions |
Notebooks are stored in a personal SharePoint Embedded container owned by the person who created them.
⚠️ Exam Trap: If a scenario needs a notebook shared read-only, with a Microsoft 365 group, or with an external partner, notebook sharing can't do it. Every invitee gets edit access, invitations go to individuals, and sharing stays inside the organization. Also, adding Teams, SharePoint or OneDrive content as a notebook reference needs a Microsoft Copilot license, even though standard files can be added without one.
Reflection Question: A strategy analyst has 20+ Copilot chats about an emerging market and wants her three teammates to build on the research with Copilot, but her manager should only be able to read it. How do notebooks help, and which part of her plan won't work as described?
