  - Support contact information

### Email Configuration
- **Provider**: Mailtrap (configured for testing)
- **Template**: `app/Notifications/MicrosoftLoginInvitation.php`

## 🔍 Troubleshooting

### Common Issues:

#### 1. "User not found" Error
**Cause**: User email not registered in system
**Solution**: Create user account first, then send invitation

#### 2. "Account not active" Error
**Cause**: User status is not 'active'
**Solution**: Activate user account in admin panel

#### 3. "Invalid redirect URI" Error
**Cause**: Mismatch between Azure AD and application configuration
**Solution**: Verify redirect URI in Azure AD matches `MICROSOFT_REDIRECT_URI`

#### 4. "Authentication failed" Error
**Cause**: OAuth configuration issues
**Solution**: Check environment variables and Azure AD app settings

### Debug Mode
Enable detailed logging by setting in `.env`:
```env
LOG_LEVEL=debug
```
