GitHub Notifications and GitHub Copilot are merged into one GitHub app in Microsoft Teams. The legacy app will be deprecated in November 2026, so users should switch to the new GitHub app.
Enhanced Personalization in Microsoft Copilot now includes Work Insights, which learns from work content such as Teams chats, transcripts, and emails. Admins and users can turn Enhanced Personalization on or off.
Microsoft is retiring the individual Copilot actions for OneDrive files from the Windows File Explorer context menu. They are replaced by one action: Ask Copilot.
B2B guest users can now register a passkey in an external organization that hosts the collaboration and use it to meet the organization's multifactor authentication requirements.
New Outlook and Outlook on the web can now run spell check automatically when a user selects Send. The setting is off by default and is configured by each user individually.
Microsoft retires Audio Overviews for PDFs in the Copilot mobile app. Overviews generated earlier can no longer be played back.
The PDF viewer in OneDrive and SharePoint on the web now supports comments anchored to a spot or to selected text, with replies and @mentions.
Edge administrators can now set a severity threshold and get alerts only for Microsoft Edge updates with security fixes at or above that level, including zero-day fixes.
Global Admins can now show their organization's logo, optionally with a label like “Managed by”, in the footer of Copilot Chat. It's off by default.
Teams now blurs images with QR codes from external senders by default. Users can reveal them, but the reveal is kept only for the current session and platform.
