使用PowerShell查询成员为空的通讯组

查询输出组织内所有组成员为空的通讯组，可用于清理组成员为空的通讯组：

$DistrGroups = Get-DistributionGroup -ResultSize Unlimited
ForEach ($DistrGroup in $DistrGroups) {
if (!$(Get-DistributionGroupMember -Identity $DistrGroup.’DistinguishedName’)) {
Write-Host $DistrGroup.DisplayName “,” $DistrGroup.PrimarySmtpAddress “,” $DistrGroup.ManagedBy
}
}
