Question

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)}}

tukan回答的结果：

VERBOSE: Subject: How are things

Answer 1

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

Answer 2

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）
