Pipeline get-mailbox and get-mailboxstatistics

Question

Dears,
I am finding great difficulty in having output what seems to be a quite simple...
I just need to output all user's mailbox prohibitsendquota and the totalitemsize and I am running the below command but it is giving me null values in totalitemsize,
Get-Mailbox -ResultSize Unlimited  | Select-Object DisplayName, ProhibitSendQuota, @{label="TotalItemSize";expression={(Get-MailboxStatistics $_name).TotalItemSize}}
However, when I make get-mailbox -identity
[email protected] it gives me the correct output...I need to run it for everyone.

.. i noticed that too, but chaning $_name to $_.name  still doesnt work - it gives me totalitemsize only on the last subject
However, i have a script i use (not one-liner though) - giving me way more information
$mailboxes = get-mailbox -database $(read-host "enter database") |select -first 10 | select name,alias,database
$Mycol = @()
foreach ($mbx in $mailboxes)
$mbxstat = get-mailboxstatistics $mbx.name |select lastlogontime,lastloggedonuseraccount,totalitemsize,itemcount
$user = get-aduser $mbx.name -properties enabled,lastlogondate
$MyObject = New-Object PSObject -Property @{
mbxName = $mbx.name
mbxAlias = $mbx.alias
mbxDatabase = $mbx.database
ADuser = $user.enabled
ADuserLogon = $user.lastlogondate
mbxLastlogon = $mbxstat.lastlogontime
mbxLastAccount = $mbxstat.lastloggedonuseraccount
mbxItemSize = $mbxstat.totalitemsize
mbxCount = $mbxstat.itemcount
$Mycol += $MyObject
$Mycol |select mbxname,mbxalias,mbxdatabase,aduser,aduserlogon,mbxlastlogon,mbxlastaccount,mbxitemsize,mbxcount #|export-csv report.csv -Delimiter ";"
