Microsoft 365 Changes

30 Days

• June 11, 2026 - Copilot Notebooks is a new feature in Microsoft OneNote.  Copilot Notebooks are AI-powered workspaces designed to gather and selectively ground on the references in the notebook, using Copilot to answer questions or create context-aware content.  OneNote notebooks focus on collecting and organizing notes, ink, and other information that you can share with others. They serve as long-term knowledge repositories.  Copilot Notebooks is available to Microsoft 365 Copilot and Copilot Chat licensed users.
• June 2026 - Microsoft will be retiring the Together Mode meeting view in Microsoft Teams. The Teams gallery is the default meeting view across Teams clients and will remain the primary multi-participant layout for meetings.
• June 2026 - Microsoft Teams will standardize the preview experience for Word, Excel, and PowerPoint files across desktop and mobile, improving speed and reliability. PowerPoint and Excel previews are on iOS and Android; Word preview is iOS only (Android later).
• June 2026 - Classic Outlook will feature user-initiated Copilot insights. Users can manually select text and ask Copilot to help provide relevant information.

• April 15, 2026 - Microsoft will no longer include Copilot Chat (basic) in Microsoft Office, Excel, OneNote, and PowerPoint apps.  Previously, Copilot Chat appeared either through a side pop-out window or as an icon on the toolbar. This change affects both online and desktop versions of these applications. Copilot Chat in Microsoft 365 Apps is only available with a paid M365 Copilot License. 
• April 14, 2026 - Microsoft Teams App bar will be simplified to create a cleaner and more focused experience, reduce clutter, and improve navigation. Users can show/hide this app bar with shortcuts (Ctrl + \ on Windows and CMD + \ on Mac).
