Getting Started

Install the Add-in

Open Microsoft Outlook on the web (outlook.office.com) or the new Outlook for Windows. Click the three-dot menu in the toolbar and select Get Add-ins. Search for Zephyr, then click Add. The Zephyr icon will appear in your toolbar on every email you open. If your organization manages add-ins centrally, your admin may have already installed it for you.

Sign In

Open any email and click the Zephyr icon in the toolbar to launch the side panel. You will be prompted to sign in with your Microsoft account. Zephyr uses secure OAuth 2.0 authentication, so your password is never shared with us. Once signed in, you are ready to go.

Your First AI Action

With an email open, you will see a row of action buttons at the top of the Zephyr panel. Tap Draft Reply to generate a smart response, or try Summarize to get a quick overview of a long thread. Each action takes just one click and results appear in seconds.

Quick Actions Overview

Zephyr gives you one-tap access to the most common email tasks: draft a reply, summarize a thread, extract action items, translate, check tone, fix grammar, and more. You can also type / in the chat box to explore 30+ slash commands for power-user shortcuts like inbox triage, meeting prep, and email tracking.
