Search Outlook Emails with Natural Language Queries using GPT-4o

This workflow allows you to search your Outlook mailbox with natural language. You type what you’re looking for (e.g., “invoice from last week”), and the workflow:

  1. Uses OpenAI to generate a search query.
  2. Searches Outlook emails and ranks them by relevance.
  3. Outputs results in a simple table with score + link to each email.

👉 The number of results can be changed (default: 5).
