Context-aware AI Capabilities

explanation for non-techies**

Imagine you're at a large conference, and you have a personal assistant who knows everything about the event. This assistant can whisper helpful tips and information in your ear as you move from session to session. Now, picture this assistant being able to instantly provide you with relevant details about the session you're attending, the people you're meeting, or even the emails you're reading on your phone. This is similar to what the new Copilot Chat overlay in Outlook Mobile aims to do for users on iOS and Android devices.

Starting from late September 2025, Outlook Mobile will begin to include a feature called Copilot Chat overlay. This feature is like having a digital assistant that can provide you with personalized, on-screen help while you're using your email, calendar, or contacts. It uses context-aware technology, meaning it understands what you're currently looking at on your screen and can offer advice or information relevant to that content. For example, if you're reading an email about a meeting, Copilot can help you by summarizing key points or suggesting actions based on the email's content.

For those with Microsoft 365 Copilot licenses, this feature will be automatically available, and you won't need to do anything to activate it. The rollout will be completed by early March 2026, and it will be available to users worldwide, including those in government sectors.

The integration of Copilot Chat into Outlook Mobile doesn't change any existing permissions or controls within your organization. It's simply an added layer of assistance to make your interaction with emails and calendar events more efficient and personalized. Just like your conference assistant, Copilot is there to make your digital experience smoother and more informed, without requiring any extra effort on your part.
