## Quickstart

### Install

#### Claude Desktop

Add this to your Claude Desktop configuration file (`%APPDATA%\Claude\claude_desktop_config.json` on Windows):

**For published package (recommended):**
```json
{
  "mcpServers": {
    "outlook-windows-com": {
      "command": "outlook-mcp-server-windows-com",
      "env": {}
    }
  }
}
```

**For development/source installation:**
```json
{
  "mcpServers": {
    "outlook-windows-com": {
      "command": "uv",
      "args": ["--directory", "C:\\path\\to\\outlook-mcp-server-windows-com", "run", "python", "-m", "outlook_mcp_server"],
      "env": {}
    }
  }
}
```

**Using system Python:**
```json
{
  "mcpServers": {
    "outlook-windows-com": {
      "command": "python",
      "args": ["-m", "outlook_mcp_server"],
      "env": {}
    }
  }
}
```

## Usage

### Running the Server

```bash
# If installed from PyPI
outlook-mcp-server-windows-com

# Or using Python module
python -m outlook_mcp_server

# From source with UV
uv run python -m outlook_mcp_server
```

### Testing

```bash
# Test server functionality (all platforms)
python test_client.py

# Or test directly with UV
uv run python test_client.py

# WSL-specific comprehensive test
./test_wsl.sh  # Only in WSL environment

# Test Windows COM access manually
python -c "import win32com.client; print('✅ COM available')"
```

### Platform Detection
The server includes automatic platform detection:

```python
import platform

if platform.system() == "Windows":
    try:
        import win32com.client
        WINDOWS_COM_AVAILABLE = True
    except ImportError:
        WINDOWS_COM_AVAILABLE = False
else:
    WINDOWS_COM_AVAILABLE = False
```

### Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging
experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector).


You can launch the MCP Inspector via [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) with this command:

```bash
npx @modelcontextprotocol/inspector uv --directory /path/to/outlook-mcp-server-windows-com run python -m outlook_mcp_server
```


Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.

## Troubleshooting

### Windows Issues

**"Failed to connect to Outlook"**
- Ensure Outlook is running and properly configured
- Check that your Outlook profile is set up correctly
- Try restarting Outlook and the MCP server
- Run Outlook as administrator if needed

**"Windows COM interface not available"**
- Install pywin32: `pip install pywin32`
- Restart your command prompt/terminal after installation

### WSL Issues

**"pywin32 not available in WSL"**
```bash
# Install pywin32 in WSL
pip install pywin32

# Or install with WSL extras
pip install outlook-mcp-server-windows-com[wsl]
```

**"Failed to connect to Outlook from WSL"**
- Ensure Outlook is running on the Windows host (not in WSL)
- Try running Outlook as administrator on Windows
- Check that WSL has proper Windows integration enabled
- Verify Windows Defender/antivirus isn't blocking COM access

**WSL COM Access Issues**
- Some WSL configurations may block COM access
- Try running the test script: `./test_wsl.sh`
- Consider using WSL 2 for better Windows integration
- Ensure your WSL distribution is up to date

**Testing WSL Environment**
```bash
# Run comprehensive WSL test
./test_wsl.sh

# Manual test of COM access
python3 -c "import win32com.client; print('COM available')"
```

### General Issues

**"Import errors in IDE"**
- Import errors for MCP libraries are normal in development
- The server will work correctly when run in the proper environment

**Permission Errors**
- Try running your terminal/command prompt as administrator
- Check that Outlook isn't in "safe mode"
- Verify your user has proper permissions to access Outlook
