Opportunities**

Enhanced User Support through AI Summarization
The integration of Microsoft 365 Copilot Chat into Edge allows users to ask contextual questions about multiple documents and tabs, improving productivity and reducing the time spent searching for information. This is particularly beneficial for roles such as project managers and team leaders who need quick access to information across various platforms.
   - next-steps: Conduct training sessions for users to familiarize them with the new features of Copilot Chat. Monitor usage and gather feedback to assess its impact on productivity.

explanation for non-techies**

Microsoft is introducing a new feature in Microsoft Edge for Business that will allow users to interact with Microsoft 365 Copilot Chat in a more integrated way. Think of Copilot as a helpful assistant sitting next to you while you work on your computer. This assistant can now look at multiple things you're working on, like different browser tabs, documents in Word or Excel, and even YouTube videos, and give you summaries or answer questions about them.

Imagine you're in a library with a knowledgeable friend. You're reading a book, watching a documentary, and taking notes all at the same time. Instead of having to focus on each one separately, you can ask your friend to quickly summarize the book, explain the documentary, or clarify your notes. This is similar to what Copilot will do in Edge—it will help you manage and understand multiple pieces of information at once.

This feature will be available starting in mid-March 2026, but it won't be turned on automatically. It respects existing rules about data protection, so if there are any restrictions on accessing certain information, Copilot will not overstep those boundaries. Think of it like a security guard ensuring that your friend only helps with the books and videos you have permission to use.

For this to work, users need to be signed into Microsoft Edge with an Entra ID and have access to Microsoft 365 Copilot. No extra setup is needed from administrators before the feature rolls out, but they should ensure that users who need this feature have the right access and permissions.

Overall, this update aims to make it easier for users to handle and understand information from various sources without having to switch back and forth between them. It's like having a smart assistant who can juggle multiple tasks and help you focus on what's important.
