Powershell：使用 EWS 搜索不在收件箱中的电子邮件答案

【问题标题】：Powershell: Using EWS to search for email which is not in the InboxPowershell：使用 EWS 搜索不在收件箱中的电子邮件

【问题描述】：

我可以搜索并找到收件箱中存在的电子邮件。但是，如果同一电子邮件位于不同的文件夹中，我该如何搜索。我正在遍历根目录并沿着列表向下移动，但是当我进行搜索时，它不会返回任何内容。我收到了来自https://docs.microsoft.com/en-us/archive/blogs/santhse/get-readstatus 的一些提示。它在大多数情况下都有效，尽管在代码中创建了一个文件夹“TEMP-MSG-ID”，并且当运行此代码超过 50,000 多个用户时，文件夹创建很少中断。所以我试图找到一种适用于所有邮箱的方法。这是我的代码：

$MsgSubject = "Complete Language"
$AdminName = "a34d4557@wyx.com"
$Pass = "password"
$User_Email = "hil@wyx.com"

$credential = new-object -typename System.Management.Automation.PSCredential -argumentlist $AdminName, $Pass
$AdminPass = $credential.GetNetworkCredential().password
$dllpath = "C:\Program Files\Microsoft\Exchange\Web Services\2.2\Microsoft.Exchange.WebServices.dll" 
[void][Reflection.Assembly]::LoadFile($dllpath) 
$service = new-object Microsoft.Exchange.WebServices.Data.ExchangeService 
$Service.Credentials = New-Object Microsoft.Exchange.WebServices.Data.WebCredentials($AdminName,$AdminPass)
$TestUrlCallback = {
    param ([string] $url)
    if ($url -eq "https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml") {$true} else {$false}
}

$service.AutodiscoverUrl($User_Email,$TestUrlCallback)
$PropertySet = New-Object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties)
$PropertySet.RequestedBodyType = [Microsoft.Exchange.WebServices.Data.BodyType]::Text

$mb = New-Object Microsoft.Exchange.WebServices.Data.Mailbox($User_Email) 
$InboxFolder = New-Object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Inbox, $mb) 

#---------------------------------------------------
# ----- If email is in Inbox -- Works correctly ----
#---------------------------------------------------
$numOfEmailsToRead = 100
$index = 0
$view = New-Object Microsoft.Exchange.WebServices.Data.ItemView($numOfEmailsToRead,$index)
$search1 = New-Object   Microsoft.Exchange.WebServices.Data.SearchFilter+ContainsSubstring([Microsoft.Exchange.WebServices.Data.ItemSchema]::Subject, $MsgSubject, [Microsoft.Exchange.WebServices.Data.ContainmentMode]::Substring, [Microsoft.Exchange.WebServices.Data.ComparisonMode]::IgnoreCase)
$UserMsgRecd = $service.FindItems($InboxFolder,$search1,$view)

#----------------------------------------------------------------------------------------------
# ----- If email is not in the Inbox but different folder -- Need to get this part to work ----
#----------------------------------------------------------------------------------------------
$RootFolder = New-Object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Root, $mb) 

$EWSParentFolder = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$RootFolder) 
$FolderView = New-Object Microsoft.Exchange.WebServices.Data.FolderView(100)
$FolderView.Traversal = [Microsoft.Exchange.WebServices.Data.FolderTraversal]::Deep
$MailboxFolderList = $EWSParentFolder.FindFolders($FolderView) 
$UserMsgRecd = $service.FindItems($EWSParentFolder,$search1,$FolderView)

我建议您使用图表中的 /messages 端点使用的 AllItems Search 文件夹。要在 EWS 中使用它，您需要先搜索它以找到 FolderId，然后您可以在 FindItems 方法中使用它，例如

$MsgSubject = "Complete Language"
$AdminName = "a34d4557@wyx.com"
$Pass = "password"
$User_Email = "hil@wyx.com"

$credential = new-object -typename System.Management.Automation.PSCredential -argumentlist $AdminName, $Pass
$AdminPass = $credential.GetNetworkCredential().password
$dllpath = "C:\Program Files\Microsoft\Exchange\Web Services\2.2\Microsoft.Exchange.WebServices.dll" 
[void][Reflection.Assembly]::LoadFile($dllpath) 
$service = new-object Microsoft.Exchange.WebServices.Data.ExchangeService 
$Service.Credentials = New-Object Microsoft.Exchange.WebServices.Data.WebCredentials($AdminName,$AdminPass)
$TestUrlCallback = {
    param ([string] $url)
    if ($url -eq "https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml") {$true} else {$false}
}

$service.AutodiscoverUrl($User_Email,$TestUrlCallback)
$PropertySet = New-Object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties)
$PropertySet.RequestedBodyType = [Microsoft.Exchange.WebServices.Data.BodyType]::Text

$mb = New-Object Microsoft.Exchange.WebServices.Data.Mailbox($User_Email) 
$folderidcnt = new-object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Root, $mb)
$fvFolderView = New-Object Microsoft.Exchange.WebServices.Data.FolderView(1)
$fvFolderView.Traversal = [Microsoft.Exchange.WebServices.Data.FolderTraversal]::Shallow;
$SfSearchFilter = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+IsEqualTo([Microsoft.Exchange.WebServices.Data.FolderSchema]::DisplayName, "allitems") 
$findFolderResults = $Service.FindFolders($folderidcnt, $SfSearchFilter, $fvFolderView) 

$numOfEmailsToRead = 100
$index = 0
$view = New-Object Microsoft.Exchange.WebServices.Data.ItemView($numOfEmailsToRead,$index)
$search1 = New-Object   Microsoft.Exchange.WebServices.Data.SearchFilter+ContainsSubstring([Microsoft.Exchange.WebServices.Data.ItemSchema]::Subject, $MsgSubject, [Microsoft.Exchange.WebServices.Data.ContainmentMode]::Substring, [Microsoft.Exchange.WebServices.Data.ComparisonMode]::IgnoreCase)
$UserMsgRecd = $service.FindItems($findFolderResults.Folders[0] ,$search1,$view)
