Exchange - listing mailboxes in an OU with their mailbox size - powershell

Question

I'm trying to display all the mailboxes and their sizes for all our users in our Departed OU. I seem to be very close but my command seems to be adding some padding to the results.
[PS] C:\Windows\system32>dsquery user "ou=Departed,ou=Staff,dc=COMPANY,dc=local" -limit 4 | dsget user -samid | Get-MailboxStatistics | ft DisplayName, TotalItemSize, ItemCount
And the output:
Dsquery has reached the specified limit on number of results to display; use a different value for the -limit option to
display more results.The specified mailbox " samid " doesn't exist.
+ CategoryInfo : NotSpecified: (0:Int32) [Get-MailboxStatistics], ManagementObjectNotFoundException
+ FullyQualifiedErrorId : DD7D7CEA,Microsoft.Exchange.Management.MapiTasks.GetMailboxStatistics
The specified mailbox " Eka.Tian " doesn't exist.
+ CategoryInfo : NotSpecified: (1:Int32) [Get-MailboxStatistics], ManagementObjectNotFoundException
+ FullyQualifiedErrorId : 7F701DFD,Microsoft.Exchange.Management.MapiTasks.GetMailboxStatistics
Obviously shouldnt work for the first result "samid" but "Eka.Tian" exists. Why is it adding all those spaces? Is there a way I could format the output from dsget user so it plays nice with Get-MailboxStatistics?

Answer 1

Why the dsquery?
get-mailbox -OrganizationalUnit "ou=Departed,ou=Staff,dc=COMPANY,dc=local" -resultsize unlimited |
get-mailboxstatistics | ft DisplayName,TotalItemSize,Itemcount

Answer 2

I've got something for you, even though it's a little late.
You just need to adjust every Searchbase with OU and DC, the Email-Adresses at the end and the SMTP-Server, then you get an Email with a CSV-Attachment that contains every OU with Counts of active and inactive Mailboxes and a list with every mailbox and its parameters.
You can also trigger it with the Task-Scheduler of Windows, so it's an automatic report.
