+# Outlook Email Backup Tool
+
+A Python GUI application that exports emails from Microsoft Outlook/Exchange accounts to local files using the Microsoft Graph API.
+
+## Features
+
+- **Dual Authentication Methods:**
+  - Interactive OAuth2 login (browser-based)
+  - Service account credentials (Client Credentials flow)
+
+- **Multiple Export Formats:**
+  - MBOX (single file, compatible with Thunderbird/Outlook)
+  - EML (individual files per email)
+  - Both formats simultaneously
+
+- **Flexible Options:**
+  - Include/exclude attachments
+  - Preserve folder structure
+
+
+## Requirements
+
+### System Requirements
+- Python 3.7 or higher
+- Windows, macOS, or Linux
+- Microsoft Azure Account (for application registration)
+
+## Installation
+
+1. Clone or download the project
+2. Install Python dependencies:
+```bash
+pip install requests
+```
+
+3. Register an Azure Application
+
+## Azure Application Setup
+
+You need to register an application in Azure AD to use this tool. Follow these steps:
+
+### 1. Register Application in Azure Portal
+
+1. Go to [Azure Portal](https://portal.azure.com)
+2. Navigate to "Azure Active Directory" → "App registrations"
+3. Click "New registration"
+4. Fill in the details:
+   - **Name:** e.g., "Outlook Backup Tool"
+   - **Supported account types:** "Accounts in this organizational directory only" (single-tenant)
+   - **Redirect URI:** 
+     - For interactive login: `http://localhost:8000`
+     - For service account: Leave empty
+5. Click "Register"
+
+### 2. Configure API Permissions
+
+1. In the app settings, go to "API permissions"
+2. Click "Add a permission"
+3. Select "Microsoft Graph"
+4. Choose **Delegated permissions** (for interactive login) OR **Application permissions** (for service account):
+   - Search and select:
+     - `Mail.Read`
+     - `Mail.ReadWrite`
+     - `offline_access` (only for interactive login)
+5. Click "Add permissions"
+
+### 3. For Service Account Method Only
+
+1. Go to "Certificates & secrets"
+2. Click "New client secret"
+3. Set expiration and create
+4. **Copy the secret value immediately** (you won't see it again)
+
+### 4. Get Your Credentials
+
+From the app overview page, copy:
+- **Application (client) ID** - Use as "Client ID"
+- **Directory (tenant) ID** - Use as "Tenant ID"
+
+## Usage
+
+### Running the Application
+
+```bash
+python ExportOutlookMailbox.pyw
+```
+
+Or on Windows, you can double-click the `.pyw` file.
+
+### Authentication Methods
+
+#### Method 1: Interactive OAuth2 Login (Recommended for Users)
+
+1. Select "Interactive login (OAuth2)" radio button
+2. Click "Connect"
+3. A dialog will ask for:
+   - **Client ID** (from Azure app registration)
+   - **Tenant ID** (from Azure app registration)
+   - **Redirect URI** (default: `http://localhost:8000`)
+4. Your default browser will open - sign in with your email
+5. After authentication, you'll be redirected back to the app
+6. The tool will be ready to backup emails
+
+#### Method 2: Service Account (Client Credentials Flow)
+
+1. Select "Service account (Client Credentials)" radio button
+2. Credential fields will appear
+3. Fill in:
+   - **Client ID** - From Azure app registration
+   - **Tenant ID** - From Azure app registration
+   - **Client Secret** - Created in "Certificates & secrets"
+4. Enter the email address of the mailbox to backup
+5. Click "Connect"
+
+### Backup Process
+
+1. **Select authentication method** and provide credentials
+2. **Enter email address** to backup (for service account method)
+3. **Choose export format:**
+   - MBOX - Recommended for single archive file
+   - EML - Individual files per email (better for editing)
+   - Both - Export in both formats
+4. **Select options:**
+   - ☑ Include attachments (uncheck to skip attachments)
+   - ☑ Preserve folder structure (mirror Outlook folder hierarchy)
+5. **Select output folder** - Where to save the backup
+6. **Click "START BACKUP"** - Start the backup process
+7. **Monitor progress** - Watch the log and progress bar
+8. **Click "STOP BACKUP"** to cancel if needed
+
+### Output Structure
+
+```

+├── Inbox/
+│   ├── message1.eml
+│   ├── message2.eml

+├── Sent Items/
+│   ├── message1.eml
+│   ├── message2.eml
+│   └── Sent Items.mbox
+├── Archive/
+│   └── ...
+```
+
+## Export Formats Explained
+
+### MBOX Format
+- **Single file** containing all emails from a folder
+- **Compatible with:** Thunderbird, Outlook, Apple Mail, many email clients
+
+### EML Format
+- **Individual files** for each email (one .eml file per message)
+- **Compatible with:** All email clients
+
+## Troubleshooting
+
+### Error: "Authentication failed"
+
+- **Interactive login:**
+  - Verify Client ID and Tenant ID are correct
+  - Check that permissions are granted in Azure AD
+  - Ensure redirect URI matches exactly in Azure (including http vs https)
+
+- **Service account:**
+  - Verify Client Secret hasn't expired
+  - Confirm application has required permissions
+  - Check email address format
+
+### Error: "Folder access denied"
+
+- The mailbox account may have restricted shared mailbox permissions
+- For shared mailboxes with service account, ensure proper delegation
+
+### Port 8000 already in use
+
+- Change redirect URI in Azure app settings
+- Update the redirect URI in the tool
+- Use a different port (e.g., `http://localhost:8001`)
+
+
+## API Limits
+
+Microsoft Graph API has rate limits:
+- 4 requests per second (for multi-tenant apps)
+- The tool includes delays to stay within limits
+
+If you hit rate limits:
+- The tool will retry automatically
+- Try with "Stop" and continue later
