Power Automate Key Default Timeouts

 Key Default Timeouts

Component	Default Timeout Limit	Notes
Overall Cloud Flow Run	30 days	This is the maximum time a flow can run before timing out, including pending steps like approvals.
Synchronous Actions (e.g., HTTP requests)	120 seconds (2 minutes)	This applies to operations where the flow waits for an immediate response.
Individual Action Connections	30 seconds (for most)	This is the time an action waits to establish a connection or receive a response before retrying or failing.
"Do Until" Loops	1 hour	This default can be adjusted up to a maximum of 5,000 iterations or a custom timeout.
Approvals (if not specified)	30 days	The "Start and wait for an approval" action will wait up to the flow's maximum run duration if no specific timeout is set. It is a best practice to set a shorter timeout for this action.
Desktop Flow Session Creation	3 minutes	The time allowed for Power Automate for desktop to create a Windows session for unattended runs.

How to Adjust Timeouts

You can configure timeout and retry policies for many individual actions within the flow designer. 

1. Select the ellipsis (...) menu on the desired action card.
2. Select Settings.
3. Configure the Timeout (using the ISO 8601 duration format, e.g., PT5M for 5 minutes) and Retry Policy.
4. Select Done and save your flow.
