Advanced Features
HTML Email Support
You can send rich HTML-formatted emails by setting the isHtml parameter to true:
Send an HTML email to john@example.com with the subject "Project Update" and body "<h1>Project Update</h1><p>We've made <b>significant progress</b> on the project.</p>"
File Attachments
You can attach files to your emails by providing the file paths in the attachments parameter:
Send an email to jane@example.com with subject "Monthly Report" and attach the reports/march_2025.pdf file
For best results with attachments:
- Use absolute file paths when possible
- Make sure the files are accessible to the process running the MCP tool
- Attachments will automatically be handled with robust error detection
Troubleshooting
If you encounter issues with attachments:
- Check if the file exists and is readable
- Use absolute file paths instead of relative paths
- Make sure the user running the process has permission to read the file
If you encounter the error Cannot find module '@modelcontextprotocol/sdk/server/index.js':
- Make sure you've run
bun install to install all dependencies - Try installing the MCP SDK explicitly:
bun add @modelcontextprotocol/sdk@^1.5.0
- Check if the module exists in your node_modules directory:
ls -la node_modules/@modelcontextprotocol/sdk/server/
If the error persists, try creating a new project with Bun:
mkdir -p ~/yourpath/claude-outlook-mcp
cd ~/yourpath/claude-outlook-mcp
bun init -y
Then copy the package.json and index.ts files to the new directory and run:
bun install
bun run index.ts
Update your claude_desktop_config.json to point to the new location.
