The Microsoft Outlook Trigger node has a polling option, I use “Every Minute”.
In the home/executions list, I only see executions for new emails sent / received.
My question : it this node consuming an execution credit every minute ? Or is it working like a wehbook ?
I’m confused
Thanks
good day @Steph67
I’d be careful treating this as webhook-like behavior. The Outlook Trigger uses polling, so it checks Outlook on the configured interval even if no new email is found. In n8n Cloud, executions started by polling/triggers can count toward usage, so with “Every Minute” you should assume this may impact your execution quota. The best way to confirm for your specific plan is to check the Executions/Usage page after letting it run for a short test period with no new emails. If cost is a concern, increasing the polling interval is the safest option.
on “home/executions” I don’t see any execution every minute, that’s why i’m asking. And I’m doing it self hosted before configuriting this in production for my customers, so I don’t see any credit usage
is there a way to see the “credit consumption” when n8n is self hosted ? Just to confirm
@Steph67
If you’re self-hosted and you don’t see executions created every minute in Home → Executions, that strongly suggests empty polling checks are not being logged as normal workflow executions in your setup. In other words, the Outlook Trigger may be polling internally, but only creating an execution when a new email is actually found. For your customers, the safest answer is still to validate this on the target environment (especially n8n Cloud plans), because polling behavior and usage/billing visibility can differ from what you see on self-hosted.
