Short Version
You will soon be able to include email in your Copilot prompts without manually uploading them. Due mid to late September 2025.
Microsoft update 5th September: “Access to emails by typing ‘/’ in the prompt box will only be available when using Copilot Chat in Outlook. This applies to both the full app and side pane experience”.
Details
By typing ‘/’ in the prompt box (Copilot in Outlook), you will be able to search and reference relevant emails. Suggested prompts beneath the input box will also include relevant emails to help you get started.
Applies to users with a license (Microsoft 365 Copilot users) when they are toggled to web scope in chat and to users without a Microsoft 365 Copilot license (Copilot Chat users).
Of course, you will only see content you have access to, based on interaction signals (such as accessed, modified, or shared) and properties (such as creation or last update date).

Due mid to late September 2025.
