The Run After mechanism

Every action in a flow has a Run After setting that controls when it executes based on the previous action's outcome:

Scopes as try/catch blocks

A Scope action groups several actions. The whole scope can have a Run After configuration. This gives you try/catch:

Retry policies

Most connector actions have built-in retry policies for transient failures (network blips, throttling). Configurable per action:

Throttling and rate limits

Microsoft 365 connectors throttle aggressively at scale. A flow that runs once an hour is fine; a flow processing 10,000 records concurrently will throttle.

Idempotency

Design flows so re-running them produces the same result as running once. For actions that change state:

Alerting

Critical flows need active alerts on failure, not just logs. Patterns:
