Workaround available Web Updated November 14, 2026Based on 4 user reportsHow we research

Quick answer

A 429 means a connector's rate limit was hit. Add retry with exponential backoff or a Delay, lower concurrency, filter queries to fetch fewer items, or move heavy flows to a Process license.

Most likely fix: Slow down the calls

How to fix it

Try these in order — the most common fix is first.

  1. 1. Slow down the calls

    1. On the action open Settings and set Retry policy to exponential
    2. Add a Delay action inside Apply to each
    3. Lower concurrency control in trigger or loop settings
    Did this fix it?

  2. 2. Do less work

    1. Use Filter query and Top count on Get items actions
    2. Store repeated values in Initialize variable
    3. Reduce schedule frequency
    Did this fix it?

  3. 3. Get more capacity

    1. Have a tenant admin buy a Premium or Process license
    2. Resave the flow so it picks up the license
    3. Split a data-heavy flow into several using Save As
    Did this fix it?

Symptoms

An action fails with 429 and text such as 'Rate limit is exceeded. Try again in 27 seconds', or the flow runs slowly.

Why it happens

  • Connector throttling (SharePoint caps 600 calls per minute per connection)
  • Daily action limit for the plan
  • Loops with high concurrency
  • Many flows sharing one connection
