2. Install required dependencies:

pip install mcp>=1.2.0 pywin32>=305

3. Configure Claude Desktop (or your preferred MCP client) to use this server

Configuration

Add the following to your MCP_client_config.json file:

{
  "mcpServers": {
    "outlook": {
      "command": "python",
      "args": ["Your path\\outlook_mcp_server.py"],
      "env": {}
    }
  }
}

Usage

Starting the Server

You can start the server directly:

python outlook_mcp_server.py

Or allow an MCP client like Claude Desktop to start it via the configuration.

Available Tools

The server provides the following tools:

1. list_folders: Lists all available mail folders in Outlook
2. list_recent_emails: Lists email titles from the specified number of days
3. search_emails: Searches emails by contact name or keyword
4. get_email_by_number: Retrieves detailed content of a specific email
5. reply_to_email_by_number: Replies to a specific email
6. compose_email: Creates and sends a new email

Example Workflow

1. Use list_folders to see all available mail folders
2. Use list_recent_emails to view recent emails (e.g., from last 7 days)
3. Use search_emails to find specific emails by keywords
4. Use get_email_by_number to view a complete email
5. Use reply_to_email_by_number to respond to an email

Examples

Listing Recent Emails

Could you show me my unread emails from the last 3 days?

Searching for Emails

Search for emails about "project update OR meeting notes" in the last week

Reading Email Details

Show me the details of email #2 from the list

Replying to an Email

Reply to email #3 with: "Thanks for the information. I'll review this and get back to you tomorrow."

Composing a New Email

Send an email to [[email protected]](/cdn-cgi/l/email-protection) with subject "Meeting Agenda" and body "Here's the agenda for our upcoming meeting..."

Troubleshooting

• Connection Issues : Ensure Outlook is running and properly configured
• Permission Errors : Make sure the script has permission to access Outlook
• Search Problems : For complex searches, try using OR operators between terms
• Email Access Errors : Check if the email ID is valid and accessible
• Server Crashes : Check Outlook's connection and stability

Security Considerations

This server has access to your Outlook email account and can read, send, and manage emails. Use it only with trusted MCP clients and in secure environments.

Limitations

• Currently supports text emails only (not HTML)
• Maximum email history is limited to 30 days
• Search capabilities depend on Outlook's built-in search functionality
• Only supports basic email functions (no calendar, contacts, etc.)
