Get items in all Outlook folders using EWS (PowerShell)

Question

Hi All,
I'm trying to figure out how to search all items in Outlook mailbox using EWS. I have a script that currently search "Sent Items" only. See script below. I just need to modify it to search all folders instead. Any help is appreciated. Thank you
