通过Powershell获取Outlook中最旧的项目

我正在做一件事,从我的桌面Outlook应用程序中提取信息。它适用于我试用过的大多数文件夹,但对于一些有近十年电子邮件的文件夹,我会遇到一个“获取‘ReceivedTime’的异常:“内存不足,无法继续执行程序。”这就是我要尝试的:

# New Outlook object
$ol = new-object -comobject "Outlook.Application";

# MAPI namespace
$mapi = $ol.getnamespace("mapi");

# Folder/Inbox
$folder =  $mapi.Folders.Item('name@email.com').Folders.Item('Inbox')

# Sort by the Received Time
$contents = $folder.Items | sort ReceivedTime

# Get the first element in the array, convert to JSON, and then output to file
echo $contents[0] | convertTo-Json | Out-File C:\Users\ME\outlook_1.json -Encoding UTF8

有更好的方法吗?我在Powershell 5.1上。

编辑:我也尝试过这个方法,在数组中循环,然后在第一个实例中中断,但收到了相同的错误:

# New Outlook object
$ol = new-object -comobject "Outlook.Application";

# MAPI namespace
$mapi = $ol.getnamespace("mapi");

# Folder/Inbox
$folder =  $mapi.Folders.Item('name@email.com').Folders.Item('Inbox')

# Sort by the Received Time
$contents = $folder.Items | sort ReceivedTime

$i = 1
foreach($item in $contents){
    if (-not ([string]::IsNullOrEmpty($item))){
        echo $item | convertTo-Json | Out-File Out-File C:\Users\ME\outlook_1.json -Encoding UTF8-Encoding UTF8
        Break
    }
}
