Outlook Weekly Calendar Summary with OpenAI

This beginner-friendly n8n workflow automates fetching your Outlook calendar events for the current week and generating an AI-powered summary using OpenAI's GPT-4o model. It starts with a manual trigger to test the workflow, retrieves events via the Microsoft Outlook node (selecting subject and start fields), normalizes ISO dateTimes into YYYY-MM-DD format using a Code node, filters for specific week days, aggregates the data, and passes it to OpenAI for a short, readable summary.

Key benefits include time-saving by consolidating scattered calendar events into a single digest, reducing manual review time for busy professionals. It demonstrates essential n8n skills like API credential setup (Outlook OAuth2 and OpenAI), data transformation (Code, Filter, Aggregate nodes), and AI integration for natural language processing.

Use cases: Weekly planning for executives, team leads needing event overviews without opening Outlook, or anyone integrating calendars with AI for insights. Easily customize filters for different weeks or add notifications via email/Slack nodes. Perfect for productivity automation starters.
