EWS 如何使用 powershell 获取子文件夹

如何解决EWS 如何使用 powershell 获取子文件夹

使用此代码：

$folderview = New-Object Microsoft.Exchange.WebServices.Data.FolderView(100)
$folderview.PropertySet = New-Object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.Webservices.Data.BasePropertySet]::FirstClassProperties)
$folderview.PropertySet.Add([Microsoft.Exchange.Webservices.Data.FolderSchema]::DisplayName)
$folderview.Traversal = [Microsoft.Exchange.Webservices.Data.FolderTraversal]::Deep
$folderfindResults = $service.FindFolders([Microsoft.Exchange.Webservices.Data.WellKnownFolderName]::Inbox,$folderview)

我可以获取邮箱中的所有文件夹。 但是如何只获取特定文件夹下的子文件夹？

收件箱 过程 一种 ...Z

我想获取所有文件夹（A...Z），以及文件夹中的项目。

解决方法

您需要使用 findFolder 方法首先找到根子文件夹，然后使用该文件夹 ID 查找它的子文件夹（与上面的相同），然后您需要查询每个子文件夹以获取其项目。要获取初始子文件夹，您可以使用类似文件夹的内容，例如在您的上下文中运行它

$Subfolder = Get-FolderFromPath -MailboxName [e-mail] -FolderPath \Inbox\Process -service $service

    function Get-FolderFromPath {
    param (
        [Parameter(Position = 0,Mandatory = $true)] [string]$FolderPath,[Parameter(Position = 1,Mandatory = $true)] [string]$MailboxName,[Parameter(Position = 2,Mandatory = $true)] [Microsoft.Exchange.WebServices.Data.ExchangeService]$service
        )
    process {
        ## Find and Bind to Folder based on Path  
        #Define the path to search should be seperated with \  
        #Bind to the MSGFolder Root  
        $psPropset = new-object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties)  
        $PidTagMessageSizeExtended = New-Object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition(0xe08,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Long);
        $PR_ATTACH_ON_NORMAL_MSG_COUNT = New-Object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition(0x66B1,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Integer);
        $psPropset.Add($PidTagMessageSizeExtended)
        $psPropset.Add($PR_ATTACH_ON_NORMAL_MSG_COUNT)

        $folderid = new-object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Root,$MailboxName)   
        $tfTargetFolder = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$folderid)  
            #Split the Search path into an array  
            $fldArray = $FolderPath.Split("\") 
            if ($fldArray.Length -lt 2) {throw "No Root Folder"}
            #Loop through the Split Array and do a Search for each level of folder 
            for ($lint = 1; $lint -lt $fldArray.Length; $lint++) { 
                #Perform search based on the displayname of each folder level 
                $fvFolderView = new-object Microsoft.Exchange.WebServices.Data.FolderView(1) 
                $fvFolderView.PropertySet = $psPropset
                $SfSearchFilter = new-object Microsoft.Exchange.WebServices.Data.SearchFilter+IsEqualTo([Microsoft.Exchange.WebServices.Data.FolderSchema]::DisplayName,$fldArray[$lint]) 
                $findFolderResults = $service.FindFolders($tfTargetFolder.Id,$SfSearchFilter,$fvFolderView) 
                $tfTargetFolder = $null  
                if ($findFolderResults.TotalCount -gt 0) { 
                    foreach ($folder in $findFolderResults.Folders) { 
                        $tfTargetFolder = $folder                
                    } 
                } 
                else { 
                    Write-host ("Error Folder Not Found check path and try again") -ForegroundColor Red
                    $tfTargetFolder = $null  
                    break  
                }     
        }  

        if ($tfTargetFolder -ne $null) {
            $tfTargetFolder | Add-Member -Name "FolderPath" -Value $FolderPath -MemberType NoteProperty
            $tfTargetFolder | Add-Member -Name "Mailbox" -Value $MailboxName -MemberType NoteProperty
            $prop4Val = $null
            if ($tfTargetFolder.TryGetProperty($PidTagMessageSizeExtended,[ref]  $prop4Val)) {
                Add-Member -InputObject $tfTargetFolder -MemberType NoteProperty -Name FolderSize -Value $prop4Val
            }
            $prop5Val = $null
            if ($tfTargetFolder.TryGetProperty($PR_ATTACH_ON_NORMAL_MSG_COUNT,[ref]  $prop5Val)) {
                Add-Member -InputObject $tfTargetFolder -MemberType NoteProperty -Name PR_ATTACH_ON_NORMAL_MSG_COUNT -Value $prop5Val
            }
            return,[Microsoft.Exchange.WebServices.Data.Folder]$tfTargetFolder
        
        }
        else {
            return,$null
        }
    }
