Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 27 nodes and runs on Microsoft Outlook events (plus 1 other trigger). Along the way it connects Embeddings OpenAI, Microsoft Outlook, OpenAI and OpenAI Chat Model and 3 more.
How it runs
Trigger: On Microsoft Outlook events (plus 1 other trigger).
- Loop Over Items (Loop Over Items (Split in Batches)): loops over the items in batches
- Supabase Vector Store: stores documents in the Supabase vector store, with embeddings: Embeddings OpenAI; document loader: Default Data Loader
- Clean HTML (Code): runs custom JavaScript code
- Update a row (Supabase): update
- Retrieve Categories (Postgres): run a query
- Aggregate: combines items into one
- Categorize (OpenAI): uses OpenAI
- Spam Filter (If): checks a condition and branches into true / false
- Conversation Retrieval (Postgres): run a query
- Format (Code): runs custom JavaScript code
…plus 6 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
