Powershell Exchange 2010 mailbox size by OU

Posted on 2014-02-24
Last Modified: 2014-04-17
Is there a way I can get the total mailbox size by OU automated. I have like 90 OU's and listing them can be a pain.

get-mailbox -OrganizationalUnit "OU=Managememt,OU=Staff,DC=company,DC=co,DC=uk" | Get-MailboxStatistics | Select @{Name="Size";Expression={$_.TotalItemSize.Value.ToMB()}} |

This should do it, you may need to output it to a csv.

foreach ($i in (Get-ADOrganizationalUnit -result unlimited)) { get-mailbox -OrganizationalUnit $i | Select @{Name="Size";Expression={$_.TotalItemSize.Value.ToMB()}}}

Foreach ($Mbx in $Mailboxes){

Get-MailboxStatistics -Identity $mbx.alias | Select @{Name="Size";Expression={$_.TotalItemSize.Value.ToMB()}}
