Outlook Calendar Automation

This automates Outlook Calendar through Composio's Rube MCP server, handling everything from event creation to finding meeting times across attendees. The workflows are thorough: create events with Teams links, search with OData filters, update attendees, decline invitations, and check free/busy schedules. The documentation is notably detailed about datetime pitfalls (ISO 8601 vs UTC with Z suffix, timezone handling) and OData quirks that will save you debugging time. Setup requires OAuth through Rube's connection manager, then you get the full Outlook Calendar API without building your own integration. Good for calendar heavy workflows where you need reliable Microsoft authentication already handled.

Automate Outlook Calendar operations through Composio's Outlook toolkit via Rube MCP.

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active Outlook connection via RUBE_MANAGE_CONNECTIONS with toolkit outlook
Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. The target account must still authenticate through the returned connection flow and grant the required scopes.

Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
Call RUBE_MANAGE_CONNECTIONS with toolkit outlook
If connection is not ACTIVE, follow the returned auth link to complete Microsoft OAuth
Confirm connection status shows ACTIVE before running any workflows
