Microsoft embeds Copilot across Edge, Office

Microsoft on May 13 pushed Copilot deeper into both its browser and workplace software, extending new AI features to the Edge mobile app and adding more Copilot entry points inside Microsoft 365 workflows. The Edge update brought tab-aware reasoning, Voice and Vision, and the Journeys feature to mobile for the first time, according to a post by Sean Lyndersay on Microsoft’s Edge blog. (blogs.windows.com) Microsoft 365 release notes published on Microsoft Learn also show new Edge for Business prompts that steer users to summarize webpages through Microsoft 365 Copilot Chat. Workday separately said on the same day that its Sana Self-Service Agent is now available inside Microsoft 365 Copilot for HR and finance requests. (newsroom.workday.com) ### What exactly changed in Edge on May 13? (learn.microsoft.com) Microsoft said the May 13 update makes Copilot available directly in Edge on desktop and, for the first time, in the Edge mobile app. The company said users can ask Copilot to reason across open tabs, use browsing history and past chats for more relevant answers, and use Voice and Vision on mobile as well as desktop. Sean Lyndersay wrote that Journeys, previously desktop-only, is now on Edge mobile and organizes browsing history into topic-based groupings with summaries and suggested next steps. Microsoft also said it is retiring Copilot Mode as it folds those features directly into the browser. (blogs.windows.com) ### Where is Copilot showing up inside Microsoft 365? Microsoft Learn release notes dated May 5 said Edge for Business now includes “contextual nudges” attached to the Copilot entry point that prompt users to summarize an open webpage through Microsoft 365 Copilot Chat. Microsoft said the feature is part of its Microsoft 365 Copilot extensibility updates and is rolling out under a safe deployment model that starts with a subset of users in a tenant. (blogs.windows.com) The same release-notes page lists a cadence of updates across Windows, web, Android, iOS and Mac, showing how Microsoft is spreading Copilot functions across existing Microsoft 365 surfaces rather than limiting them to a standalone assistant. That deployment pattern is described by Microsoft, not inferred here. (blogs.windows.com) ### Why does Workday matter in this rollout? Workday said on May 13 that its Sana Self-Service Agent is now available in Microsoft 365 Copilot, letting employees and managers ask HR and finance questions and complete tasks from inside Microsoft 365. The company said examples include checking time-off balances, updating personal information, viewing payslips, reviewing tax withholding information and requesting leave. (learn.microsoft.com) A March 17 Workday announcement said Sana Self-Service Agent launched with more than 300 skills and was already handling everyday HR and finance tasks for customers worldwide. Workday said Sana Enterprise also connects with systems including Gmail, Microsoft Outlook, Salesforce and SharePoint. (learn.microsoft.com) TechTarget reported on May 13 that employees can get answers to questions about vacations, expenses and related topics from the Copilot query line, describing the Workday integration as a way to bring frontline HR interactions into Microsoft’s assistant surface. ### What do the security disclosures show? Microsoft’s public materials available in this reporting confirm that the company has been documenting prompt-injection risks around Copilot and related agent frameworks, but the specific claim that it recently patched Copilot flaws exposing emails and documents could not be verified from the official sources reviewed here. (newsroom.workday.com) Microsoft’s July 2025 MSRC blog described its defenses against indirect prompt injection, and Microsoft’s May 7, 2026 security research blog described how prompt injection in agent frameworks can lead to remote code execution. (newsroom.workday.com) The Microsoft Security Update Guide also lists Copilot-related CVE entries, but the fetched results did not provide enough detail to attribute a specific May 2026 patch to email or document exposure inside Microsoft 365 Copilot. (techtarget.com) Because that detail could not be confirmed from the sources reviewed, it is not stated as fact here. ### What comes next? Microsoft’s Copilot release notes page says new features are introduced gradually within a tenant before broader expansion across an organization. Workday’s May 13 announcement says the Sana Self-Service Agent is available now in Microsoft 365 Copilot, while Microsoft’s Edge blog points users to its Copilot-in-Edge page and the Edge mobile app for the latest rollout.
