Use Exchange PowerShell to count old emails in inbox folder - powershell-2.0

Question

Does anyone know of a PowerShell script that uses EWS to look into a user's Exchange 2010 SP3 Inbox and get a count of email messages and the sizes older than 60 days for example? I can't believe no one has been able to do this. I see a lot of people asking how to do this. Help please :-)

There are a few example on this http://gsexdev.blogspot.com.au/2012/10/reporting-on-item-age-count-and-size-in.html and http://gsexdev.blogspot.com.au/2014/07/creating-mailbox-folder-growth-map-with.html
Specifically for what you want to do something like this should work
## Get the Mailbox to Access from the 1st commandline argument
$MailboxName = $args[0]
$DateFrom = (Get-Date).AddDays(-60)
## Load Managed API dll
Add-Type -Path "C:\Program Files\Microsoft\Exchange\Web Services\2.1\Microsoft.Exchange.WebServices.dll"
## Set Exchange Version
$ExchangeVersion = [Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2010_SP2
## Create Exchange Service Object
$service = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService($ExchangeVersion)
## Set Credentials to use two options are availible Option1 to use explict credentials or Option 2 use the Default (logged On) credentials
#Credentials Option 1 using UPN for the windows Account
$psCred = Get-Credential
$creds = New-Object System.Net.NetworkCredential($psCred.UserName.ToString(),$psCred.GetNetworkCredential().password.ToString())
$service.Credentials = $creds
#Credentials Option 2
#service.UseDefaultCredentials = $true
## Choose to ignore any SSL Warning issues caused by Self Signed Certificates
## Code From http://poshcode.org/624
## Create a compilation environment
$Provider=New-Object Microsoft.CSharp.CSharpCodeProvider
$Compiler=$Provider.CreateCompiler()
$Params=New-Object System.CodeDom.Compiler.CompilerParameters
$Params.GenerateExecutable=$False
$Params.GenerateInMemory=$True
$Params.IncludeDebugInformation=$False
$Params.ReferencedAssemblies.Add("System.DLL") | Out-Null
$TASource=#'
namespace Local.ToolkitExtensions.Net.CertificatePolicy{
public class TrustAll : System.Net.ICertificatePolicy {
public TrustAll() {
}
public bool CheckValidationResult(System.Net.ServicePoint sp,
System.Security.Cryptography.X509Certificates.X509Certificate cert,
System.Net.WebRequest req, int problem) {
return true;
}
}
}
'#
$TAResults=$Provider.CompileAssemblyFromSource($Params,$TASource)
$TAAssembly=$TAResults.CompiledAssembly
## We now create an instance of the TrustAll and attach it to the ServicePointManager
$TrustAll=$TAAssembly.CreateInstance("Local.ToolkitExtensions.Net.CertificatePolicy.TrustAll")
[System.Net.ServicePointManager]::CertificatePolicy=$TrustAll
## end code from http://poshcode.org/624
## Set the URL of the CAS (Client Access Server) to use two options are availbe to use Autodiscover to find the CAS URL or Hardcode the CAS to use
#CAS URL Option 1 Autodiscover
$service.AutodiscoverUrl($MailboxName,{$true})
"Using CAS Server : " + $Service.url
#CAS URL Option 2 Hardcoded
#$uri=[system.URI] "https://casservername/ews/exchange.asmx"
#$service.Url = $uri
## Optional section for Exchange Impersonation
#$service.ImpersonatedUserId = new-object Microsoft.Exchange.WebServices.Data.ImpersonatedUserId([Microsoft.Exchange.WebServices.Data.ConnectingIdType]::SmtpAddress, $MailboxName)
# Bind to the Inbox Folder
$folderid= new-object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Inbox,$MailboxName)
$Inbox = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$folderid)
#Define ItemView to retrive just 1000 Items
$ivItemView = New-Object Microsoft.Exchange.WebServices.Data.ItemView(250)
$psPropset= new-object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::IdOnly)
$psPropset.Add([Microsoft.Exchange.WebServices.Data.ItemSchema]::Size)
$psPropset.Add([Microsoft.Exchange.WebServices.Data.ItemSchema]::DateTimeReceived)
$psPropset.Add([Microsoft.Exchange.WebServices.Data.ItemSchema]::DateTimeCreated)
$ivItemView.PropertySet = $psPropset
$sfItemSearchFilter = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+IsLessThan([Microsoft.Exchange.WebServices.Data.ItemSchema]::DateTimeReceived,$DateFrom)
$rptObj = "" | Select Mailbox,TotalNumber,TotalSize
$rptObj.Mailbox = $MailboxName
$rptObj.TotalNumber = 0
$rptObj.TotalSize = [Int64]0
$fiItems = $null
do{
$fiItems = $service.FindItems($Inbox.Id,$sfItemSearchFilter,$ivItemView)
#[Void]$service.LoadPropertiesForItems($fiItems,$psPropset)
foreach($Item in $fiItems.Items){
$rptObj.TotalNumber += 1
$rptObj.TotalSize += [Int64]$Item.Size
}
$ivItemView.Offset += $fiItems.Items.Count
}while($fiItems.MoreAvailable -eq $true)
$rptObj | select Mailbox,TotalNumber,#{label="TotalSize(MB)";expression={[math]::Round($_.TotalSize/1MB,2)}}
