Examples

Email Operations

Check my unread emails in Outlook

Send an email to alex@example.com with subject "Project Update" and the following body: Here's the latest update on our project. We've completed phase 1 and are moving on to phase 2.

Send an HTML email to team@example.com with subject "Weekly Report" and attach the quarterly_results.pdf file

Search my emails for "budget meeting"

Calendar Operations

What events do I have today?

Create a calendar event for a team meeting tomorrow from 2pm to 3pm

Show me my upcoming events for the next 2 weeks

Contact Operations

List all my Outlook contacts

Search for contact information for Jane Smith

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':

1. Make sure you've run bun install to install all dependencies
2. Try installing the MCP SDK explicitly:

   bun add @modelcontextprotocol/sdk@^1.5.0
   

3. 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.
