Cancelling all running flows in Power Automate

Finding out that you have a scheduled flow in Power automate or Microsoft Flow (What ever name it has this week), that just continue to run and then the next flow dows the same and all of a sudden, you have a gazillion flows running and never stopping. Well according to the Power automate limits, they will be cancelled after 30 days.

But you don’t have the option to turn the flow off and the wait 30-days until you can turn it back on again – I assume. And you have a list that look like this:

The behavior mostly happens, when a workflow starts, before the previous has finished. You can take a look at this article by Pieter Veenstra on how to troubbleshoot the flow to dig deeper into the how and the why. Here is a few ways to prevent it and to deal with it.

  1. Set the degree of parallelism to 1, then you will only have one flow running. Then you will discover immediately if it hangs.
  2. Cancel all the running flows
  3. Make a copy of your flow, export it, then import it and delete your old flow (not a fan of this option but it will work)
  4. Check if lists or items or sites etc. Exists before you try to create them. If you need to check for new items in a list and run stuff for each item, then make a condition to only run, if there is any items.
  5. Make a list, with a single item that reads “locked” or “Unlocked”, then at step 1, check if item is unlocked, if not, terminate the flow. If “unlocked = true, then set it to locked, and then run flow. As a final step, set the item back to “unlocked”.

Set the degree of parallelism to 1

  1. If you have a recurring flow, click on the steps menu “…” and the “Settings”.

2. Activate “Concurrency Control” and then set the “Degree of Parallelism” to 1

Cancel all the running flows

Thank you to the ever brilliant users in the “Microsoft Power Automate Community” for delivering this solution. This is just brilliant.

  1. Navigate to the flow in question
  2. Click on “All runs”
  3. Filter the view to only show the running flows
  4. Open the console in the browser (hit F12 and the select console)
  5. Paste in the code below. For some reason I need to paste the jquery part twice before the actual action code, but it works like a charm. Depending on the number of flows you have running, this can take quite a while.
//Include jquery (you may need to paste this following twice)
var jq = document.createElement('script');
// Cancel all running flows ( This part you only paste once)
confirm = function () {return true;};
setInterval(function () {

  1. We need to know who the active site owners are of more than 4000 sites. I had a flow that sent an approval to all site owners of sites (we ran 100 at a time) and some sites have multiple owners so it looped through. After 3 days of no response it escalated to the owners manager with another approval. The approval was Yes, I own the site or No, I don’t own this site. A lot of people didn’t reply so may escalated to managers. I have some managers who own 100-400 sites so there were getting bombarded with emails. (I am going to rewrite the flow!). I ran this code and it stopped more than 700 flows from running and saved me from dealing with irate managers! Thank you!

    • Hi Bob. I am so glad that this little trick could help you out. Thank you for taking the time to write a comment and letting me know that it made a difference.
