# ✨ AI-Powered Outlook Email Automation with n8n

This repository provides a complete automation stack using **n8n**, Microsoft Outlook, Microsoft Teams, and **Google Gemini** (or another LLM). It reads incoming Outlook emails, generates a professional AI-powered draft, sends it to Teams for approval, and sends the email after one-click confirmation.

---

## 🚀 Features

- **Automated AI Drafts**: Auto-generates email replies using LLM when a new Outlook email arrives.
- **Intelligent Replies**: Context-aware, business-grade replies using Gemini or OpenAI.
- **Microsoft Teams Integration**: Sends an interactive adaptive card with the draft email.
- **One-Click Approval**: Instantly send or edit the draft via Teams.
- **Secure & Self-Hosted**: Dockerized deployment with Cloudflare SSL & reverse proxy.
- **Conversation Memory**: Retains context for threaded conversations.

---

## ✅ Prerequisites

Make sure you have the following:

- A server (VPS or dedicated) with **Docker** & **Docker Compose**
- A registered **domain name**
- A **Cloudflare** account for DNS and SSL
- A **Microsoft 365** account with admin access
- An **API Key** for Google Gemini or OpenAI

---

## 🛠️ Setup and Configuration

### Step 1: Server & Domain

- Create an A record (e.g. `n8n.yourdomain.com`) → Point to your server IP.
- On Cloudflare, set **SSL/TLS** to **Full** or **Full (Strict)**.

### Step 2: Deploy n8n with Docker

```bash
mkdir n8n-automation && cd n8n-automation
# Paste docker-compose.yml content here
docker-compose up -d
```

### Step 3: Setup Nginx Reverse Proxy

```bash
sudo nano /etc/nginx/sites-available/n8n.conf
# Paste nginx config here, update domain
sudo ln -s /etc/nginx/sites-available/n8n.conf /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl restart nginx
```

You can now access n8n at: `https://n8n.yourdomain.com`

---

### Step 4: Azure App Registration

1. Go to [Azure Portal](https://portal.azure.com)
2. Register a new App under **Microsoft Entra ID** → **App registrations**
3. Redirect URI: `https://n8n.yourdomain.com/rest/oauth2-credential/callback`
4. Get **Client ID** and **Client Secret**
5. Add these **Microsoft Graph API** permissions:
- `Mail.ReadWrite`
- `Mail.Send`
- `User.Read`
- `offline_access`
6. Grant Admin Consent.

---

### Step 5: Configure n8n Workflows

- Import the two workflows:
- `Outlook_Email_Draft_Teams_Alert.json`
- `Outlook_Email_Create_Send.json`

- Set up credentials for:
- Microsoft Outlook (OAuth2)
- Microsoft Teams
- Google Gemini / OpenAI

- Connect the webhook URL from `Send Approved Email` workflow into the Teams card in `AI Draft & Teams Alert`.

- **Activate both workflows** – You're live!

---

## 🔄 Workflows

### 1. **Outlook Email Draft + Teams Alert**

- Triggers on new unread Outlook email.
- Retrieves body and context.
- Uses Gemini/OpenAI to generate a reply.
- Creates a draft via Microsoft Graph API.
- Sends Adaptive Card to Microsoft Teams with buttons:
- ✅ **Accept & Send**
- ✏️ **Edit in Outlook**

### 2. **Teams Action → Send Email**

- Triggered when the user clicks ✅ in Teams.
- Sends the previously created draft via Microsoft Graph API.
