Hi Everyone,
I've implemented a three-step automation process for request and approval within our organization using Power Automate.
Flow 1 takes data from a Microsoft Form and moves it to a SharePoint List.
Flow 2 comes next, which locks the request to prevent further editing and sends it through a four-level approval process while updating the approval status at each stage.
Flow 3, which is designed specifically for handling items that were rejected during Flow 2's approval process. Its purpose is to allow the requester to make necessary edits and then resubmit the request through the same four-stage approval process.
The trigger for flow is "When an Item is modified" and trigger conditions are : 1)Approval status is "rejected" 2) requester email equals to modified by email. 
Everything works well for most users.
Now, the issue I'm facing is that Flow 3 isn't triggering for some users. I suspect there might be an issue with their email configurations, which is outside my control as I'm not the IT administrator.
Do you have any insights or experience in troubleshooting this kind of problem or are there common issues related to email configurations that could be causing this? I'm looking to provide some guidance to our IT team to help resolve the issue effectively."
Thanks,
Nastaran Heidari
