Execution count

[gwamm]

Hi all,

Cloud version n8n Pro

Version 1.109.2

Currently I have 2 workflows testing for ingestion of outlook inbound mail. My question is regarding executions v polling.

I have one method which is trigger every X minutes, check mailbox for unread emails > if unread > pull. But every time this runs, it uses an execution from my available monthly executions.

Another method I am testing it poll interval on outlook, which I can set to poll mode every minute. (trigger on message received)

My question is why does the first workflow use an execution if there are no unread emails (I know it uses 3 nodes before failing), and does the second method use an execution every poll attempt?

My main aim is to tune the execution count, so I would like to understand better.

Thanks!

Every time a workflow is triggered, regardless of how many nodes run or fail generates an execution, so yes, even the 1 minute polling will do that.

Hope this helps, please mar as Solution if it did

Hey Kris, thank you for your reply!
So to confirm, even using outlook polling will use an execution number?

Yep, think of it like so: if the trigger node has to actually turn on and perform any task, it will create a unique execution for that workflow => will use up executions.
