Microsoft has restricted access to Copilot AI features inside Word, Excel, PowerPoint, and OneNote, requiring a paid Microsoft 365 Copilot license starting in June 2026. Users without the subscription can still access Copilot Chat through the Microsoft 365 app or on the web. Copilot features in Outlook remain available to existing Microsoft 365 subscribers without requiring the additional Copilot license; Microsoft has not explained publicly why Outlook was treated differently. The Microsoft 365 Copilot subscription is priced at $30 per user per month for business customers, on top of the base Microsoft 365 plan. New features rolling out to Copilot license holders in June include a redesigned chat interface, a new Notebooks feature, and improved meeting recap tools in Teams. The June update also introduced Copilot agents in Visual Studio that can automatically discover and use skills defined in a repository. In 2024 and early 2025, Copilot features were more broadly available as part of the standard Microsoft 365 tier. Enterprise customers have reacted with mixed responses; some organizations have begun reviewing whether the added features justify the per-user cost. Google Workspace has taken a different approach, bundling Gemini AI features into its standard plans without a separate AI tier for most users.
