“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.

The new functionality allows users to summarize documents, compare files, generate FAQs, ask questions, and even create audio overview, all without opening the files. These actions will be available through the AI Actions button in the SharePoint toolbar or by hovering over a file. If you’re familiar with the OneDrive experience, you’ll find the interface and capabilities nearly identical, ensuring a smooth transition for users.

So, how does this compare to OneDrive? Functionally, it’s the same set of tools, but the key difference is context: OneDrive focuses on personal and shared files, while SharePoint brings these AI capabilities to team and organizational content. 

To prepare, inform your users about these new capabilities and review your Copilot licensing. This is also a great time to update your governance and adoption plans to include AI-driven workflows.

This update is part of Microsoft 365 Roadmap item 488297.
