Power Automate Underlying Architecture

(0) ShareShare

Posted on by Community Power Pla... Microsoft Employee

Hello I am a little curious about the underlying architecture behind Power Automate. My Flow is triggered when an email arrives in a mailbox. What happens if a hundred emails get sent to that mailbox in let's say a ten minute time frame? Will Power Automate queue them up using something like Azure Message Queue and process them one by one or will the Flow just start failing?

    @sharepat01  Power automate follows exchange limits in emails. Please go through this link for more clarification.

    It depends on your flow plans. If it is a free plan then flow tiggers within 5 min ( not sure it is 5 or 8). It will process one by one.

    Please 'Thumbs Up' the posts that helped you and 'Mark as Solution' if my post answered your question.

    Hi @sharepat01,

    From what I can see you are trying to test the limits of the system. Here are some articles which might be interested in:
