Powershell 更新 AD proxyAddresses

Question

我正在为 AD 用户尝试代理地址。 我假设，它不能正常工作的部分与-Add @{proxyAddresses="smtp:"+$_.alias+$proxydomain} 。

我检查了 AD 用户中的代理地址属性。 它的显示如下。

smtp:@domain.onmicrosoft.com

脚本：

 $proxydomain = "@domain.onmicrosoft.com"
    Get-ADUser -Filter {(emailaddress -like "*@contoso.com" -and Enabled -eq $true -and sAMAccountName -like "TYU*")} -SearchBase "OU=IT,DC=contoso,DC=local" -SearchScope Subtree -Properties *  | foreach-object {

    $alias=$_.mail.Split("@")[0]

        if ($_.Proxyaddresses -match $_.alias+$proxydomain  )
    {
        Write-Host "Result: ProxyAddresses value already exists for $($_.displayname); No action taken."
    }

        else
    {
      Set-ADUser -Identity $_.SamAccountName -Add @{proxyAddresses="smtp:"+$_.alias+$proxydomain}

        Write-Host "Result: Added proxyAddresses value to Account"
     }

   }

Answer 1

您首先将主邮件地址的用户部分分配给变量$alias ：

$alias=$_.mail.Split("@")[0]

但是您在以下几行中引用了$_.alias ：

if ($_.Proxyaddresses -match $_.alias+$proxydomain  )

这是行不通的，因为$_.alias解析为您当前正在处理的 ADUser object 上名为alias的属性的值 - 由于不存在名称为alias的 AD 用户属性， $_.alias的计算结果为$null 。

更改代码以评估变量，它会起作用：

$proxydomain = "@domain.onmicrosoft.com"
Get-ADUser -Filter { (emailaddress -like "*@contoso.com" -and Enabled -eq $true -and sAMAccountName -like "TYU*") } -SearchBase "OU=IT,DC=contoso,DC=local" -SearchScope Subtree -Properties *  | foreach-object {

    # grab user alias
    $alias = $_.mail.Split("@")[0]

    # construct the new address up front and assign it to a single variable
    $newProxyAddress = "$alias$proxydomain"

    # -match is a regex operator, escape appropriately
    if ($_.ProxyAddresses -match [regex]::Escape($newProxyAddress)) {
        Write-Host "Result: ProxyAddresses value already exists for $($_.displayname); No action taken."
    }
    else {
        # Now we only have a single variable that needs to be expanded in the string
        Set-ADUser -Identity $_.SamAccountName -Add @{proxyAddresses = "smtp:$newProxyAddress"}

        Write-Host "Result: Added proxyAddresses value to Account"
    }
}
