    Get-ExchangeServer
    Get-Mailbox  -Server demo  |Measure-Object

    Get-Mailbox |Where-Object  {$_.WhenCreated -ge ((Get-Date).AddDays(-7))}

5.查詢10月份創建的郵箱

    Get-Mailbox  -ResultSize  Unlimited |Where-Object  {($_.WhenCreated).month -eq 10}

6.查詢2017年創建的郵箱

    Get-Mailbox  -ResultSize  Unlimited |Where-Object  {($_.WhenCreated).year -eq 2017}

7.查詢具有“代理髮送”權限的郵箱

Get-Mailbox  -ResultSize  Unlimited  |Get-ADPermission  |Where-Object {$_.extendedrights  -like "*send-as*"}

10.查詢從未登錄過的郵箱

Get-Mailbox  -ResultSize  Unlimited  |Get-MailboxStatistics  | where {$_.lastlogontime -eq  $null}
