New Year, New Momentum: Here are three Copilot updates to get you started into 2026

It's a new year, so I thought I'd start the year by mentioning three features already released, or soon going to be released. One of the features improves the workflow of sharing files with comments, the other improves the application specific Copilot, and the last feature makes it easer to find the nest available timeslot for a 1:1 meeting. As with all of my other posts, timelines can shift, and the timelines in this post is as written in the Message Center at the time of posting. AI-Summary experience when sharing files. With this new feature, copilot intent to help users share files with clearer context in just a few steps. Users will get the capability to generate a concise summary of a file and include it when sharing from the File Explorer share dialog or the OneDrive activity center. This will make it easier to share the context of a file and giving the receiver a faster understanding of what a document or file contains before they open it. General Availability announced...

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

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.
