How To Get Deleted Item Count and Associated Item Count And LastLogOn and LogOff Time For A Mailbox In Exchange Using EWS

Question

Using Powershell cmdlet i get  all the details..But i want to get these Details by using EWS Managed Api.Is It Possible to do???
Powershell Cmdlet,
Get-MailboxStatistics -Identity Username, Using this cmdlets all the details will get displayed.
DeletedItemCount:5 //Here how this count comes.In My OutlookWebApp the deleteditems folder contains 13 items in it..But the count shows only 5.
TotalDeletedItemSize:5.465 Kb//Even this value too does not match with DeletedItems Folder size in owa.
AssociatedItemCount:12
LastLogOnTime:11/11/11 12:43PM
LastLogOff Time:11/11/11 2:43PM
In EWS,
By Looping through all folders i can get the total item count and total item size.Even i can get deleteditems  count .But that value does not match  With the powershell value.Even the TotalDeletedItemSize
Doesnt match.
Using EWS Managed Api ,Looping through folders i can get ItemCount,TotalitemSize,(DeletedItems,TotalDeleteditemSize(These TwoValues Does not match with values comes from powershell))
Now how to get the Associated item count and lastlogoff and logon time using EWS managed Api.Is it Possible???
And even y the deleteditems count and size values varies between EWS and powershell.
