May edition: Copilot for Microsoft 365 updates

Take a new look at how Microsoft Copilot can help increase your productivity and enhance the quality of your work. For May, we're highlighting how Copilot's AI lets you revisit previous chats, how local files are now accessible when writing prompts, how a conversation with Excel can get you past a blocking point, how you can create helpful summaries when you share Word docs, and how you can get transcripts for videos stored on Stream. 

If you want to see what you missed in past months, check out the updates history.

Take the power of AI on the go! Download the Microsoft Copilot mobile app and sign in with your work account today.

  • "How do I create a drop-down list"
