Summarize M365 Outage Alerts with ChatGPT & Send to Slack

This n8n workflow automates the handling of Microsoft 365 service outage alerts by polling a designated Outlook mailbox every minute. It identifies relevant emails, checks if the outage impacts specified user regions (e.g., U.S., Australia—customizable in the OpenAI prompt), and uses the cost-effective GPT-4o-mini model to generate concise summaries. The summarized incident, including a direct link, is then posted as a rich Slack block to a dedicated outage-notifications channel, supporting both desktop and mobile views.

Key benefits include streamlining alert management for IT administrators and MSPs, reducing email clutter through automatic deletion of processed messages, and enabling ChatOps for faster team response. It transforms verbose M365 emails into actionable Slack updates, saving time on manual monitoring and triage.

Ideal use cases: IT teams managing multiple M365 tenants, small MSPs centralizing alerts from shared mailboxes, or organizations preferring Slack over email for incident response. Easily extensible for additional channels or local AI models like Ollama. Low cost: ~1-2 cents/month on OpenAI.
