Three ways to use Ellie with Outlook

Pick the surface that matches how you live in your inbox. Most people start with the connected mailbox — that's the auto-draft experience.

Recommended

1. Connected Outlook (auto-drafts)

Connect Outlook.com, Microsoft 365, or Exchange Online once. Ellie reads incoming threads, categorises them, and drafts replies in your voice — straight into your Drafts folder. Nothing to install.

  • ✓ Drafts appear in Outlook on web, desktop, and mobile
  • ✓ Powered by your sent-mail history and any custom Roles or Knowledge Base you've set up
  • ✓ Auto-categorise + Auto-draft features (Business and Professional plans)
  • ✓ Microsoft 365 Government & Exchange Online supported
Connect your Outlook →
New: Outlook Desktop

2. Native Outlook desktop add-in

Trigger Ellie on demand from the Outlook ribbon — including classic Outlook for Windows and the new Outlook desktop apps. Ellie writes a reply right inside the compose window.

  • ✓ Works in classic Outlook for Windows, the new Outlook desktop apps, and Outlook on the web
  • ✓ Installed centrally for your team via Microsoft 365 admin centre
  • ✓ Same Roles and Knowledge Base as the rest of Ellie
Get it on Microsoft AppSource →
For Outlook on the web

3. Browser extension (Outlook Web)

Prefer Outlook in your browser? The Ellie extension adds a one-click reply button to the Outlook Web compose box, so you can manually trigger a draft whenever you want.

  • ✓ Works in Outlook Web, Outlook.com, and Microsoft 365 webmail
  • ✓ Available for Edge and Chrome (Edge link below)
  • ✓ Ideal alongside auto-drafts when you want to override on a specific reply

Outlook FAQ

Which Outlook accounts work?

Outlook.com, Microsoft 365 (work / school), and Exchange Online mailboxes. We use Microsoft's official OAuth flow — you sign in once and can disconnect any time from your Ellie dashboard.

Does the desktop add-in need the connected mailbox?

No. The desktop add-in works on its own as a manual reply trigger. But you'll get the auto-draft experience by also connecting your Outlook account in your Ellie dashboard.

How do I get my whole team on it?

Buy Ellie via the Microsoft AppSource SaaS listing for billing through your Microsoft account, then have your IT admin deploy the Outlook add-in to your tenant from the Microsoft 365 admin centre.

Does Ellie support shared mailboxes?

Yes — connect a shared mailbox the same way you'd connect a personal one. Auto-drafts will appear in the shared Drafts folder for the team to review.
