“Bring your AI to work” is here: Microsoft edition - What Multiple Account Access to Copilot means

on
Multiple Account Access to Copilot On October 1. 2025 Microsoft released a blog post explaining how employees now can use Copilot from their personal 365 plans to work on organizational data. This is of course, an extension of the already existing "Multi account" feature that was released for corporate accounts a "couple of months" ago. In other words, “bring your own Copilot” is now a real thing in Word, Excel, PowerPoint, Outlook, and OneNote on desktop and mobile, with enterprise protections intact. “Bring your AI to work” is an important topic, and banning AI altogether might not be the answer. Whether sanctioned or shadow, AI has already entered everyday knowledge work. Microsoft’s new multi‑account access offers a safer path where employees can use Copilot from their personal Microsoft 365 subscriptions on work files, while the file’s access, auditing, and compliance still flow through the work identity and tenant.

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.
