当我检查ContactItem时，所有Email＃Address值都为空。我已经尝试设置值然后打印值。此更改反映在Outlook中，但是，无法通过PowerShell检索任何值。
以下是一些片段：
$Outlook=NEW-OBJECT –comobject Outlook.Application
$Contacts=$Outlook.session.GetDefaultFolder(10).items
$Contactsfolders = $Outlook.session.GetDefaultFolder(10).Folders
$testFolder = $Contactsfolders | Where-Object {$_.Name -eq 'Test Folder'}
$testContact = $testFolder.Items(1)
echo $testContact
$testContact.Email1Address = "BobDoe3@doe.com"
echo $testContact
以上是上述执行的输出。请注意，我删除了一些不感兴趣的信息以缩短。

我在玩不同的结果和解决方案时发现了一些有趣的东西。
我发现以下两个查询都会产生相同的匹配，这让我感到困惑，因为我认为myString -ne ''正在检查字符串是否为空。似乎myString -ne ''和[String]::IsNullOrEmpty($myString)都可以返回true，这似乎是不可能的，但我认为在某些情况下可能会发生这种情况。另请注意，IsNullOrEmpty功能非常快。
$Listconstact=$session.GetDefaultFolder(10).Folders | %{$session.GetFolderFromID($_.EntryID).Items | where Email1Address -NE ''}
和
$Listconstact=$session.GetDefaultFolder(10).Folders | %{$session.GetFolderFromID($_.EntryID).Items | where {[String]::IsNullOrEmpty($_.Email1Address)}}

尝试这样的事情：
$Outlook=NEW-OBJECT –comobject Outlook.Application
$session=$Outlook.session
$Listconstact=$session.GetDefaultFolder(10).Folders | %{$session.GetFolderFromID($_.EntryID).Items | where Email1Address -ne ''}
#only one item
Write-Host "First element mail : $($Listconstact[0].Email1Address)`n`n"
#All mails
Write-Host "All element mail :"
$Listconstact.Email1Address

我对你要达到的目标有点模糊。对我来说，似乎你把两件事混合在一起 - 联系人和文件夹。
我不确定您是否尝试从Outlook电子邮件或地址簿中获取信息（因为您使用的是文件夹，我猜它是第一个）。如果不能解决您的问题，我很乐意纠正解决方案。
注意：我没有相同的配置但足够接近：Outlook版本： 15.0.0.4420 和PowerShell版本： 4.0.30319
我会尽力报道我认为你想要在我眼中解决的问题 - 从“测试文件夹”@Outlook
# Making sure we have the assembly loaded
Add-Type -assembly "Microsoft.Office.Interop.Outlook"
# saving the mapping
$olFolders = "Microsoft.Office.Interop.Outlook.OlDefaultFolders" -as [type]
# new object
$Outlook=NEW-OBJECT –comobject Outlook.Application
# setting the correct namespace
$namespace = $Outlook.GetNameSpace("MAPI")
# getting all folders in Outlook inbox
$inbox = $namespace.GetDefaultFolder($olFolders::olFolderInbox)
# filtering out all but the "Test Folder"
$targetFolder = $inbox.Folders.Item("Test Folder")
# iteration on email message
ForEach($emailMessage in $targetFolder.items) {
# getting all the information from the message
Write-Verbose -message "From: $($emailMessage.GetProperty) $($emailMessage.SenderEmailAddress)" -Verbose
Write-Verbose -message "Subject: $($emailMessage.Subject)" -Verbose
}
为什么 MAPI 名称空间？好吧因为MSDN says so。
我原以为myString -ne''正在检查字符串是不是 空。
是的，它确实这样做了。区别在于方法[String]::IsNullOrEmpty($myString)正在检查字符串中的Null OR 为空。如果您有$null值，那么您可以同时为true。它不是空的，是$ null。 （有关更多信息，请参阅具有$null值的含义）
