Implement an infinite loop (repeated processing)

Power Automate Desktop provides a wide range of actions for getting data from web pages and on-premises software.

However, the free version doesn’t support scheduled runs (scheduled runs require a paid license such as Power Automate Premium). Because of this, many people keep a flow running continuously without ending it, for example to monitor for a specific event.

This article explains how to implement an infinite loop.

Loop with a step of 0

This is an example of an infinite loop that uses the “Loop” action.

Implement by copying and pasting

Copy the following code and paste it into the Power Automate Desktop flow designer to add the actions.

LOOP FROM 0 TO 1 STEP 0
END

Implement in Power Automate Desktop

1. In “Search actions,” type “Loop.”

2. Set the parameters to the following values.

   Loop

   Iterates a block of actions for a specified number of times

   Select parameters

   Start from

   0

   End to

   1

   Increment by

   0

   SaveCancel

Caution

In this case, LoopIndex always stays at 0 and has no use, so the produced variable is turned off in this sample.

Infinite loop with a condition

This is an example of an infinite loop that uses the “Loop condition” action.

Implement by copying and pasting

Copy the following code and paste it into the Power Automate Desktop flow designer to add the actions.

LOOP WHILE (True) = (True)
END

Implement in Power Automate Desktop

1. In “Search actions,” type “Loop condition.”

2. Set the parameters to the following values.

   Loop condition

   Iterates a block of actions as long as a specified condition proves to be true

   Select parameters

   First operand

   %True%

   Operator

   Equal to (=)

   Second operand

   %True%

   SaveCancel

Tip

The sample specifies %True% as the operands of the condition, but what creates the infinite loop is specifying exactly the same value for “First operand” and “Second operand,” so the value can be a string or a number.
