+### Configuring a Microsoft Teams alert policy
+
+In this example, we'll configure a Teams alert for when a Hybrid Agent goes down.
+
+```yaml
+alert_policies:
+  - name: "email-alert-policy"
+    description: "An alert policy to email company executives during job failure."
+    tags:
+      - key: "level"
+        value: "critical"
+    event_types:
+      - "AGENT_UNAVAILABLE"
+    notification_service:
+      microsoft_teams:
+        webhook_url: "https://yourdomain.webhook.office.com/..."
+```
+
+If the agent stops heartbeating, a message will be sent via the [incoming webhook URL](https://docs.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-incoming-webhook).
