OL Rescue

Outlook Office Web Add-in that recreates the old “OL Helper” workflow for New Outlook (and Outlook on the web): you define a Tracking ID and an Inbox subfolder name, then the add-in uses Microsoft Graph to create the folder (if needed) and move messages that contain TrackingID#… in the subject or preview.

Classic COM/VSTO add-ins do not run in New Outlook. The supported path is Office.js + Graph, which this project uses.

What you need

  • Node.js 20+ and npm (for local HTTPS dev and builds).
  • Microsoft 365 / Outlook with add-ins allowed by your org.
  • An Azure AD app registration (see below) with Graph delegated permissions: Mail.ReadWrite, User.Read.

Azure AD app (summary)

  1. In Azure PortalMicrosoft Entra IDApp registrationsNew registration.
  2. Name it (e.g. “OL Rescue”), supported account types per your tenant, Redirect URI: platform Single-page application (SPA), URI https://localhost:3000 (and later your production URL).
  3. API permissionsMicrosoft GraphDelegated: add Mail.ReadWrite, User.ReadGrant admin consent if required.
  4. Overview → copy Application (client) ID.

Run locally

cd "/path/to/OL Rescue!"
cp .env.example .env
# Set VITE_AZURE_CLIENT_ID to your client ID
npm install
npm run dev

Vite serves HTTPS on port 3000 (self-signed cert; your browser will warn once).

Sideload the manifest in Outlook (Windows New Outlook)

  1. Ensure manifest.xml still points to https://localhost:3000/index.html (default for dev).
  2. In Outlook: FileManage Add-ins / Get Add-insMy add-insAdd a custom add-inAdd from file… → choose manifest.xml.

If your org blocks custom add-ins, an admin may need to deploy via Centralized Deployment or allow sideloading.

Use the add-in

  1. Open a ticket email and open the OL Rescue task pane.
  2. Sign in with Microsoft (Graph consent).
  3. Fill from open message to parse TrackingID#… and suggest a folder name, or type Tracking ID and Inbox folder name manually.
  4. Save case, then Create folder & move mail on that case to create Inbox\<folder name> and move matching messages.

Saved cases are stored in browser localStorage for this add-in origin.

Production

  1. Host the dist/ folder (or your static host) over HTTPS.
  2. Update Application ID URI / redirect URIs in Azure for your real origin.
  3. Edit manifest.xml SourceLocation, IconUrl, and SupportUrl to your HTTPS URLs, then rebuild (npm run build) and redeploy.

Limits vs old OL Helper

  • Not automatic on every new message unless you add something else (e.g. Outlook rules calling a service, or Power Automate). This tool is on-demand from the task pane.
  • Graph search uses $filter on subject/body preview; very unusual formats might need a small follow-up change.
  • Shared mailboxes need extra Graph permissions and possibly UX changes; this MVP targets your primary mailbox (/me/…).
