Outlook Add-in
Click-to-book Workestra meetings from inside Outlook compose windows.
The Workestra Outlook Add-in adds a "Schedule with Workestra" pane to Outlook compose windows. Users pick a booking link, offered slots, or a team page, and the add-in inserts a formatted snippet into the email body.

Installation
For enterprise launch, deploy the add-in with Microsoft 365 admin sideloading:
- Build or obtain the Outlook add-in package.
- Host the generated
taskpane.html, JavaScript bundle, andmanifest.xmlon an HTTPS origin approved by your organization. - Update the manifest URLs if you host the bundle outside the Workestra-managed origin.
- Deploy the manifest through the Microsoft 365 admin center as an organization add-in.
The package source lives in apps/outlook-addin/ of the Workestra monorepo. The package README documents local build and sideload steps for teams managing their own deployment.
After deployment, "Workestra" appears in the Outlook compose add-ins menu for assigned users.
Authentication
The add-in uses the same Workestra account session as the web app. Users sign in from the add-in pane, and the session persists across compose windows until they sign out.
For shared mailboxes, the session belongs to the user who installed or opened the add-in, not to the shared mailbox identity. Send-on-behalf-of behavior follows Microsoft 365 delegation.
Not supported
- Outlook 2016 and earlier desktop clients
- Legacy Outlook Web Access
- A public Microsoft AppSource listing before marketplace approval
- Server-side ingestion of Outlook calendar events; use Microsoft 365 Calendar for calendar sync
