php - 想在 PHP 中只读取 Exchange 服务器中收件箱中的未读邮件

Question

我只想阅读来自 Outlook Exchange 服务器的未读电子邮件。下面是我的代码。但它显示收件箱中的所有电子邮件（已读+未读）。

<?php
require_once ('../mail3/php-ews-master/ExchangeWebServices.php');
require_once ('../mail3/php-ews-master/EWS_Exception.php');
require_once ('../mail3/php-ews-master/EWSType.php');
require_once ('../mail3/php-ews-master/NTLMSoapClient.php');

function __autoload($class_name)
{
// Start from the base path and determine the location from the class name,
$base_path = '../mail3/php-ews-master';
$include_file = $base_path . '/' . str_replace('_', '/', $class_name) . '.php';

return (file_exists($include_file) ? require_once $include_file : false);
}

//$message_id = ''; // Id of the email message
$ews = new ExchangeWebServices("webmail.bangla.com", "dd.test",  "************",ExchangeWebServices::VERSION_2010);

$request = new EWSType_FindItemType();
$request->ItemShape = new EWSType_ItemResponseShapeType();
$request->ItemShape->BaseShape = EWSType_DefaultShapeNamesType::DEFAULT_PROPERTIES;

$request->ParentFolderIds = new EWSType_NonEmptyArrayOfBaseFolderIdsType();
$request->ParentFolderIds->DistinguishedFolderId = new  EWSType_DistinguishedFolderIdType();
$request->ParentFolderIds->DistinguishedFolderId->Id = EWSType_DistinguishedFolderIdNameType::INBOX;

$request->Traversal = EWSType_ItemQueryTraversalType::SHALLOW;

$result = $ews->FindItem($request);
var_dump($result);
?>

请让我知道我能做什么。我只想阅读未读邮件。阅读后应标记为已读。

提前致谢。
