Fetch and process oldest email in the inbox using EWS Managed API - exchange-server

Question

I'm using the script below along with EWS Managed API 2.2 to grab emails and read To and Sender property. It works fine for all emails, but i want to make it fetch, process oldest email (1x at the time), then move/delete it. Is there a way to set filters or arrange it to achieve the below, or anyone has ever worked on something like this?
##########
$mail= "useraa#domain.com"
$password="password"
# Set the path to your copy of EWS Managed API
$dllpath = "C:\Program Files\Microsoft\Exchange\Web Services\2.2\Microsoft.Exchange.WebServices.dll"
# Load the Assemply
[void][Reflection.Assembly]::LoadFile($dllpath)
# Create a new Exchange service object
$service = new-object Microsoft.Exchange.WebServices.Data.ExchangeService
#These are your O365 credentials
$Service.Credentials = New-Object Microsoft.Exchange.WebServices.Data.WebCredentials($mail,$password)
# Autodiscover using the mail address set above
$service.AutodiscoverUrl($mail)
# create Property Set to include body and header of email
$PropertySet = New-Object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties)
# set email body to text
$PropertySet.RequestedBodyType = [Microsoft.Exchange.WebServices.Data.BodyType]::Text;
# Set how many emails we want to read at a time
$numOfEmailsToRead = 1
# Index to keep track of where we are up to. Set to 0 initially.
$index = 0
# Do/while loop for paging through the folder
do
{
# Set what we want to retrieve from the folder. This will grab the first $pagesize emails
$view = New-Object Microsoft.Exchange.WebServices.Data.ItemView($numOfEmailsToRead,$index)
# Retrieve the data from the folder
$findResults = $service.FindItems([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Inbox,$view)
foreach ($item in $findResults.Items)
{
# load the additional properties for the item
$item.Load($propertySet)
# Output the results
$To = $($item.ToRecipients)
$From = $($item.Sender)
}
# Increment $index to next block of emails
$index += $numOfEmailsToRead
} while ($findResults.MoreAvailable) # Do/While there are more emails to retrieve

Any help is very much appreciated.
Thanks

In your ItemVeiw you can use OrderBy and sort it ascending eg after the line
$view = New-Object Microsoft.Exchange.WebServices.Data.ItemView($numOfEmailsToRead,$index)
add
$view.OrderBy.add([Microsoft.Exchange.WebServices.Data.ItemSchema]::DateTimeReceived,[Microsoft.Exchange.WebServices.Data.SortDirection]::Ascending)
