Get items in all Outlook folders using EWS (PowerShell)

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

$Report = @()

#Provide text files for all users in the legal department
$Law = cat law.txt

#Set Date to 1 Year Ago
$Date = (Get-Date).AddYears(-1)
	

#Logon to Exchange Web Service with default credentials	
	Add-Type -Path "C:\Program Files\Microsoft\Exchange\Web Services\1.2\Microsoft.Exchange.WebServices.dll"
    $sid = [System.Security.Principal.WindowsIdentity]::GetCurrent().User.Value
    $user = [ADSI]"LDAP://<SID=$sid>"        
    $service = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService -ArgumentList ([Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2010_SP2)
    $service.AutodiscoverUrl($user.Properties.mail)

Write-Progress -Activity "Preparing" -Status "Retrieving mailbox list" -PercentComplete 0

#Get Mailboxes for all users in the text file
$Mailboxes = $law | Get-User  | Select WindowsEmailAddress, Company

$Count = $Mailboxes.Count


#Go through each users found and process accordingly
ForEach ($Mailbox in $Mailboxes){
		$DisplayName = $Mailbox.DisplayName
		$i = $i + 1
		$pct = $i/$Count * 100
		Write-Progress -Activity "Collecting mailbox details" -Status "Processing mailbox $i of $Count - $DisplayName" -PercentComplete $pct
