推荐答案

您的代码将始终绑定到您使用的安全凭据的邮箱，因为如果您要使用的则没有包括任何模拟代码(您的代码注释表明了这一点)，或者如果您要使用委托访问，则需要使用FolderId重载.

Your code will always bind to the Mailbox of the Security credentials your using because you haven't included any impersonation code if that's what you want to use (your code comments indicate this) or if you want to use delegate access you need to use the FolderId overload.

要进行模拟，您需要添加

For impersonation you need to add

$service.ImpersonatedUserId = new-object Microsoft.Exchange.WebServices.Data.ImpersonatedUserId([Microsoft.Exchange.WebServices.Data.ConnectingIdType]::SmtpAddress, $MailboxName) 

还添加锚点邮箱标题，例如

Also add the Anchor mailbox header eg

$service.HttpHeaders.Add("X-AnchorMailbox", $MailboxName);

对于委派甚至是假冒，我都会使用

For delegation or even with impersonation i would use

    $folderid = new-object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Root, $MailboxName)   
    $oFindFolderResults = $service.FindFolders($folderid,$oSearchFilter,$oFolderView)

这将确保您始终在$ MailboxName变量中搜索邮箱

That will ensure your always searching the Mailbox in the $MailboxName variable

要删除项目，请尝试类似的操作(其中$ Calendar是目标文件夹)

for deleting items try something like (where $Calendar is you target folder)

$ivItemView = New-Object Microsoft.Exchange.WebServices.Data.ItemView(1000)  
$fiResult = ""  
do{  
    $fiResult = $Calendar.FindItems($ivItemView)  
    $type = ("System.Collections.Generic.List" + '`' + "1") -as "Type"
    $type = $type.MakeGenericType("Microsoft.Exchange.WebServices.Data.ItemId" -as "Type")
    $Itemids = [Activator]::CreateInstance($type)
    "Delete " + $fiResult.Items.Count + " Items"  
    foreach($Item in $fiResult.Items){  
        $Itemids.Add($Item.Id)  
    }  
    #Delete the Items  
    $Result = $service.DeleteItems($Itemids,[Microsoft.Exchange.WebServices.Data.DeleteMode]::SoftDelete,[Microsoft.Exchange.WebServices.Data.SendCancellationsMode]::SendToNone,[Microsoft.Exchange.WebServices.Data.AffectedTaskOccurrence]::AllOccurrences)  
    [INT]$Rcount = 0  
    foreach ($res in $Result){  
        if ($res.Result -eq [Microsoft.Exchange.WebServices.Data.ServiceResult]::Success){  
            $Rcount++  
        }  
    }  
    $Rcount.ToString() + " Items deleted successfully"  
    $ivItemView.offset += $fiResult.Items.Count  
}while($fiResult.MoreAvailable -eq $true)
