PowerShell脚本从特定的Outlook文件夹中提取.xls文件

Question

我想从每天收到的电子邮件中提取并保存.xls文件。 我有一个规则设置，将电子邮件保存在收件箱的特定子文件夹中的Outlook邮箱中。

Outlook文件夹结构如下所示：

-> Inbox

--> Data (subfolder of "Inbox")

---> ToExtract (subfolder of "Data")

我需要从“ ToExtract”文件夹中提取.xls文件。

我找到了一个脚本 ，可以为我完成大部分工作，但是它需要用户监督该脚本并手动选择要搜索的Outlook文件夹。 我需要更改脚本，使其仅指向“ ToExtract”子文件夹。

代码如下。 它工作正常，但我需要修改pickfolder()部分。

#file path
$filepath = “c:\test\”


#set outlook to open
$o = New-Object -comobject outlook.application
$n = $o.GetNamespace(“MAPI”)


#you'll get a popup in outlook at this point where you pick the folder you want to scan
$f = $n.pickfolder()

#date string to search for in attachment name
$date = Get-Date -Format yyyyMMdd


#now loop through them and grab the attachments
$f.Items | foreach {
    $_.attachments | foreach {
    Write-Host $_.filename
    $a = $_.filename
    If ($a.Contains($date)) {
    $_.saveasfile((Join-Path $filepath $a))
      }
  }
}

Answer 1

试一下。

$Account = $n.Folders | ? { $_.Name -eq 'username@domain.com' };
$Inbox = $Account.Folders | ? { $_.Name -match 'Inbox' };
$f = $Inbox.Folders | ? { $_.Name -match 'ToExtract' };
