在Azure自动化中获取隔离消息

如果我在Azure Automation中尝试下面的脚本，我会得到错误get QuarantineMessages不可识别

此cmdlet在Azure Automation中不起作用

 $MyCredential = "O365Credential" 
 $subject = "Mail send from Azure Automation using Office 365" 
 $userid='xistoso@xistoso.ca' 

# Get the PowerShell credential and prints its properties 
$Cred = Get-AutomationPSCredential -Name $MyCredential 
if ($Cred -eq $null) 
{ 
    $Body = Write-Output "Credential entered: $MyCredential does not exist in the automation service. Please create one `n"    
} 
else 
{ 

$ExchangeOnlineSession=New PSSession-ConfigurationName Microsoft.Exchange-ConnectionUri-Credential$Cred-Authentication Basic-AllowDirection-Name$ConnectionName 导入模块（导入PSSession-会话$ExchangeOnlineSession-AllowClobber-DisableNameChecking）-全局

$today=获取日期
$Dayed=（获取日期）.AddHours（-1）
$Body=获取检疫信息-入站方向-StartReceivedDate$昨天-EndReceivedDate$今天
}
