OneNote: 6 New Tools + Copilot Notebooks

Key insights

• This YouTube video summarizes the OneNote Fall 2026 update and shows how Copilot Notebooks become a persistent AI workspace that stores project context for ongoing work.
  
• Microsoft expands access with Copilot Notebooks for all users and licenses, so teams and individual users can create shared knowledge spaces without limiting participation to premium Copilot seats.
  
• You can add more reference types to notebooks — new support includes Markdown, TXT, and RTF plus Word, Excel, PowerPoint, Outlook emails, Teams meeting content, Copilot chats and web links — making notebooks a central place for mixed-format project sources.
  
• Copilot automates routine tasks inside the notebook, handling actions like organizing notes, drafting content, extracting action items, and producing structured outputs from the collected references.
  
• Direct Office editing and interactive outputs let you edit Word, Excel, and PowerPoint files from the notebook and generate infographics, study guides, and interactive reports without leaving OneNote.
  
• The Copilot app adds an "Open in OneNote" link, lets you choose desktop or browser as the default for opening links, and OneNote now supports MathML for better, more accessible math content.
  

Overview: What Mike Tholfsen showed

In a recent YouTube video, Mike Tholfsen walked viewers through the Fall 2026 updates to OneNote and the expanded Copilot Notebooks experience. He highlighted six headline changes, including broader access, new reference types, direct Office editing, and improved math handling through MathML. As a result, the video frames this release as a step toward turning note-taking into a more complete project workspace rather than a simple reference store. Consequently, this update aims to reduce friction for teams that move between notes, documents, meetings, and chats.

Tholfsen’s presentation focused on how these features work together in practice, and he demonstrated common workflows such as creating infographics and study guides within a notebook. He also pointed out the new link behavior that offers an "Open in OneNote" option from the Copilot app and a choice between desktop or browser as the default. Therefore, users gain both richer content options and finer control over how links open. This balance matters for users who prefer desktop power but still want quick browser access.

Expanded availability and practical effects

Importantly, Microsoft 365 has widened access to Copilot Notebooks, moving them beyond a small set of premium Copilot users to many more Microsoft account types. Tholfsen noted that Microsoft 365 Personal, Family, Premium, and Pro subscribers now have broader availability, although some storage or service plans like SharePoint or OneDrive may still be required. As a result, teams can collaborate in a shared notebook even when members do not have identical license levels. This wider reach lowers the barrier to using a shared, AI-grounded knowledge space.

However, wider availability introduces tradeoffs. On one hand, more users can create and access project context without repeatedly explaining the background, which improves continuity. On the other hand, organizations will need to manage storage, permissions, and license entitlements to avoid unexpected costs or access gaps. Thus, IT teams must weigh user convenience against governance and budget planning.

New reference types and direct Office editing

The update broadens the kinds of files you can add to a notebook, including Markdown, TXT, and RTF, alongside traditional Office formats such as Word, Excel, and PowerPoint. Tholfsen demonstrated that notebooks can collect emails, meeting content, chats, and web links so that AI can use varied sources when answering questions or producing outputs. This expanded format support makes the notebook a realistic hub for project materials that rarely live in a single file type.

Moreover, the ability to edit Office files directly inside a notebook changes the workflow by reducing context switching between apps. Users can apply full Word, Excel, or PowerPoint capabilities from within the notebook, which speeds up lightweight edits and collaborative work. Nevertheless, this integration raises practical questions about version control, simultaneous edits, and where the authoritative copy lives. Therefore, teams should set clear practices for editing and storing files to avoid conflicts.

AI delegation, outputs, and tradeoffs

A notable shift is that Copilot can now delegate simple tasks from within the notebook, such as organizing information, creating drafts, or extracting action items. Tholfsen showed how the assistant can generate structured outputs like infographics and Study Guides, which helps users turn raw notes into polished deliverables. Consequently, the notebook becomes a place where work can move forward automatically rather than just a passive archive.

Yet automation introduces tradeoffs between speed and control. While delegation saves time on routine jobs, it may also surface errors if the assistant misinterprets context or omits nuance. To balance this, users should review AI-created outputs and maintain oversight for critical decisions. In short, automation boosts productivity but requires responsible review and validation.

Math support, link controls, and adoption challenges

The October update also adds MathML support, which helps users work with math content more accurately and accessibly inside notes. Tholfsen emphasized that this change benefits educational and technical users who need precise math rendering and manipulation. At the same time, relying on advanced formats introduces compatibility considerations for downstream tools and archiving. Therefore, teams and educators should test workflows to confirm that math content remains usable across platforms.

Finally, the update includes usability improvements such as a clearer "Open in OneNote" link and the option to set desktop or browser as the default for OneNote links. These settings make life easier for users who prefer a specific interface, but they also increase the number of choices IT must document and support. Adoption will depend on training, governance, and how organizations manage permissions and storage. Overall, Tholfsen’s video shows thoughtful, practical improvements, while also reminding viewers that broader access, automation, and richer formats require careful planning and ongoing oversight.
