查找用户是否是某些通讯组列表的一部分

Question

我想让一个脚本在 powershell 中工作，它获取用户的电子邮件并根据几个分发列表查找它以查看用户是否是其中任何一个的一部分。它还应检查嵌套通讯组如果在主要分发列表下有的话。

这是我所拥有的，但无法正常工作。任何帮助将不胜感激，我对此很陌生。

# Prompt for user email address
$UserEmail = Read-Host -Prompt 'Please enter the user email address'

# Read the CSV file
$DistributionLists = Import-Csv -Path '.\DLs.csv'

# Loop through each Distribution List
foreach ($DL in $DistributionLists) {
    # Get List of Distribution Group Members
    $GroupMembers = Get-DistributionGroupMember -Identity $DL -ResultSize Unlimited

    # Loop through each member
    foreach ($Member in $GroupMembers) {
        # Check if the user's email address matches
        if ($Member.PrimarySmtpAddress -eq $UserEmail) {
            # Output the matches
            Write-Output "User $UserEmail is a part of $($DL.Name)"
        }
    }
}

但我在执行时遇到以下错误：

Write-ErrorMessage : Cannot process argument transformation on parameter 'Identity'. Cannot convert value "" to type
"Microsoft.Exchange.Configuration.Tasks.DistributionGroupMemberIdParameter". Error: "Parameter values of type Microsoft.Exchange.Configuration.Tasks.DistributionGroupMemberIdParameter can't be empty. Specify a value, and try again.

错误语句告诉我们“-Identify $DL”为空； $DL 返回整个对象行，而不仅仅是要匹配的名称。要更正，请重构为 $DL.DistributionLists，其中“DistributionLists”是导入的 CSV 文件中的列标题。

正如我们一起确认的那样，您已经导入了 ExchangeOnlineManagement 并连接到 Exchange Online...。我将这些保留在下面的代码中以供将来的读者参考。

# Pearl-script below:
# Import the ExchangeOnlineManagement module
Import-Module ExchangeOnlineManagement

# Connect to Exchange Online
Connect-ExchangeOnline

# Prompt for user email address
$UserEmail = Read-Host -Prompt 'Please enter the user email address'

# Read the CSV file
$DistributionLists = Import-Csv -Path '.DLs.csv'

# Loop through each Distribution List
foreach ($DL in $DistributionLists) {
    # Get List of Distribution Group Members
    $GroupMembers = Get-DistributionGroupMember -Identity $DL.DistributionLists -ResultSize Unlimited

    # Loop through each member
    foreach ($Member in $GroupMembers) {
        # Check if the user's email address matches
        if ($Member.PrimarySmtpAddress -eq $UserEmail) {
            # Output the matches
            Write-Output "User $UserEmail is a part of $($DL.DistributionLists)"
        }
    }
}
