尝试使用PowerShell回复电子邮件。脚本工作正常。但原始电子邮件和我的回复之间没有电子邮件分隔符（灰色线）。下面是我的代码。

Add-Type -assembly "Microsoft.Office.Interop.Outlook"
Add-type -assembly "System.Runtime.Interopservices"

try
{
$outlook = [Runtime.Interopservices.Marshal]::GetActiveObject('Outlook.Application')
    $outlookWasAlreadyRunning = $true
}
catch
{
    try
    {
        $Outlook = New-Object -comobject Outlook.Application
        $outlookWasAlreadyRunning = $false
    }
    catch
    {
        write-host "You must exit Outlook first."
        exit
        
    }
}

$namespace = $Outlook.GetNameSpace("MAPI")

$inbox = $namespace.GetDefaultFolder([Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderInbox)

$mails = $inbox.Items | Where-Object {$_.Subject -like "ABC TEST*"}

$mailsbody = $mails | Select-Object -Property Body | Format-List

$text = "Test Body"

foreach($mail in $mails) {
    $reply = $mail.reply()
    $reply.body = $reply.body.Insert(0, $text) + [Environment]::NewLine
    $reply.send()
    while(($namespace.GetDefaultFolder([Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderOutbox)).Items.Count -ne 0) {
        Start-Sleep 1
    }
}

# Kill Process Outlook (close COM)
Get-Process "*outlook*" | Stop-Process –force
