Power shell Outlook 互操作程序集问题

Question

我正在尝试使用 PowerShell 脚本从文件夹中的 Outlook 项目中提取附件。代码是：`

# Specify the folder containing Outlook item files (.msg)
$sourceFolder = "C:\GRAINGER\GRAINGER\06-07-2023 Placements"

# Specify the parent folder where you want to save attachments
$saveFolder = "C:\GRAINGER\GRAINGER\Attachments\06-07-2023 Placements A"

# Load the Outlook COM Object
Add-Type -TypeDefinition @"
    using System;
    using Microsoft.Office.Interop.Outlook;
"@

# Create an Outlook Application object
$outlook = New-Object -ComObject Outlook.Application

# Get a list of .msg files in the source folder
$msgFiles = Get-ChildItem $sourceFolder -Filter *.msg

# Loop through each .msg file and extract attachments
foreach ($msgFile in $msgFiles) {
    $mailItem = $outlook.Session.OpenSharedItem($msgFile.FullName)

    # Create a folder with the same name as the Outlook item file
    $itemFolder = New-Item -Path "$saveFolder\$($msgFile.BaseName)" -ItemType Directory

    # Loop through each attachment in the email
    foreach ($attachment in $mailItem.Attachments) {
        $attachment.SaveAsFile("$itemFolder\$($attachment.FileName)")
    }

    # Close the mail item
    $mailItem.Close()
}

# Release Outlook objects
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($attachment) | Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($mailItem) | Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($outlook) | Out-Null

我不断收到如下错误： 类型或命名空间名称“Office”确实 命名空间“Microsoft”中不存在（您是否缺少程序集引用？） CategoryInfo : InvalidData: (Microsoft.Power...peCompilerError:AddTypeCompilerError) [添加类型]，除外 离子 +FullyQualifiedErrorId：SOURCE_CODE_ERROR，Microsoft.PowerShell.Commands.AddTypeCommand

我安装了office 365，还安装了outlook。但我被困在这里...

您需要先添加互操作dll

Add-Type -AssemblyName "Microsoft.Office.Interop.Outlook"

或者您可以跳过整个

Add-Type -TypeDefinition @"

块并使用后期绑定而不依赖互操作。
