Do until in the new Power Automate Designer

The new Power Automate designer is getting a lot of negative attention. There are however a quite a few improvements in new Power Automate Designer. The Do Until step is one of those improvements in the new UI.

Do Until

In the classic UI, I’ve seen many used the Do Until often in combination with variables as shown below where we run some actions inside a Do Until before a variable is set before the Do Until step will check the value of the variable.

In the classic UI you might think that the Do until condition would be checked before the first iteration of the Do Until. But this does not happen. A Do Until will always run once before it checks the condition.

First of all, this is not a matter of using variables or not. Whereas in Apply to each steps variables disable concurrency in Do until loops there is no concurrency setting, hence it doesn’t matter if you use variables or not. Other than less is often better.

When we run some more tests you will find that the variable steps are actually not needed at all. As the condition can check values from steps returned by steps inside the Do Until.

Now it is time to have a look at the modern Power Automate Designer UI.

Now, when we look at the new UI, we will see that the condition follows the logic in the Do Until. This mean that you would expect the code to run once before the Do Until checks if a condition is met.

This is one of those many UI changes that actually makes sense. Have you found any real positive changes in the new UI, then leave a comment below.
