Sharing your Copilot notebooks - Is being rolled out

on
Microsoft is rolling a new update to Copilot Notebooks that make collaboration even easier: the ability to share Copilot Notebooks with your colleagues.  Personally, I like Notebooks because they feel almost like small, personal agents I don’t have to configure. They give me a safe space to collect notes and documents and then work on them over time. With this update, that personal space can become a shared space for a selected group of  colleagues, without compromising security or permissions. I think it is also important to note that your chat and chat history within the Notebook stays private. The web rollout began in late October and will finish by December, while mobile access starts in early November and are related to the Microsoft 365 Roadmap ( ID 506851 )  You can also read more about the Copilot Notebooks experience on the Microsoft website here .

Microsoft Purview Sensitivity Labels: Sensitivity label grouping modernization coming this fall (?)

on

There is a change coming to Microsoft Purview Information Protection that simplifies sensitivity label architecture. The goal is to make label management easier, more scalable, and less rigid for organizations.

The new model will only include standalone labels and sublabels. Parent labels will be replaced by label groups, which act as organizational containers. These groups cannot be applied to content and have no actions or scope, but they retain color and priority for visual organization. Hopefully, this change will make it much easier to move labels around and make other changes in production: for example, converting a standalone label into a sublabel or moving sublabels between groups without breaking dependencies. 

From my experience, this update solves one of the biggest challenges in large environments: rigid label hierarchies. The new dynamic model gives admins the agility they need to adapt quickly as compliance and business needs evolve.

For admins, migration will be quick and simple. Eligible tenants will see a manual migration wizard in the Purview portal. After migration, you’ll have full flexibility to reorganize labels. End users won’t notice any changes in how labels appear or work.

Originally planned for July 2025, the Public Preview has been pushed to December 2025, with General Availability to be announced later. Because timelines can shift, I strongly recommend monitoring the Microsoft 365 Roadmap ID 386900 for the latest updates.
