You may soon be able to use AI in Microsoft Word, Outlook

Washington Post - Technology News 

You can prompt the chat to give you milestones of a project you're working on, and it will search across apps and documents to present you with answers, offering citations of where it got those answers, for example. You can then continue the conversation and ask it to summarize its answer or infer what risks might be related to the project. Then you can turn that into an action by asking the chat to draft an email to specific colleagues including the summary and risks. If you like the draft, you can click to make the chat open Outlook and transfer all the data to the right fields, so that the subject moves to the subject line and the content is automatically pasted into the body of the email.
