我已经能够使用php-ews API成功地从Exchange 2010收件箱中检索未读电子邮件。但是，在我提取电子邮件后，我想将电子邮件的IsRead属性设置为true，这样下次提取电子邮件时就不会出现这些消息。
以前有人这样做过吗？
编辑：
这就是我试图设置IsRead标志的方式：
$message_id = ''; //id of message
$change_key = ''; //change key
$response = $ews->GetItem($request);
//print_r($response);exit;
if( $response->ResponseMessages->GetItemResponseMessage->ResponseCode == 'NoError' &&
$response->ResponseMessages->GetItemResponseMessage->ResponseClass == 'Success' ) {
$a = array();
$message = $response->ResponseMessages->GetItemResponseMessage->Items->Message;
$a['message_body'] = $message->Body->_;
$a['sender'] = $message->From->Mailbox->EmailAddress;
$a['subject'] = $message->ConversationTopic;
$data[] = $a;
//process the message data.
$messageType = new EWSType_MessageType();
$messageType->IsRead = true;
$path = new EWSType_PathToUnindexedFieldType();
$path->FieldURI = 'message:IsRead';
$setField = new EWSType_SetItemFieldType();
$setField->Message = $messageType;
$setField->FieldURI = $path;
$u = new EWSType_ItemChangeType();
$u->Updates = new EWSType_NonEmptyArrayOfItemChangeDescriptionsType();
$u->Updates->SetItemField = $setField;
$u->ItemId = new EWSType_ItemIdType();
$u->ItemId->Id = $message_id;
$u->ItemId->ChangeKey = $change_key;
$updatedItems = new EWSType_NonEmptyArrayOfItemChangesType();
$updatedItems->ItemChange = $u;
$updateMessenger = new EWSType_UpdateItemType();
$updateMessenger->ItemChanges = $updatedItems;
$updateMessenger->MessageDisposition = 'SaveOnly';
$updateMessenger->ConflictResolution = 'AutoResolve';
try {
$update_response = $ews->UpdateItem($updateMessenger);
}catch (Exception $e){
echo $e->getMessage();
}
}
当我运行文件时，我得到以下错误：
An internal server error occurred. The operation failed.
经过一段时间的调试，我得出结论，错误发生在NTLMSoapClient.php文件中的curl_exec函数处。
我不知道从这里开始该往哪里走。请帮忙。
我在更新日历事件和设置IsAllDayEvent标志时也遇到过类似的问题。这是对我有效的代码：
$ews = new ExchangeWebServices(...);
$request = new EWSType_UpdateItemType();
$request->ConflictResolution = 'AlwaysOverwrite';
$request->ItemChanges = array();
$change = new EWSType_ItemChangeType();
$change->ItemId = new EWSType_ItemIdType();
$change->ItemId->Id = $id;
$change->ItemId->ChangeKey = $changeKey;
$field = new EWSType_SetItemFieldType();
$field->FieldURI = new EWSType_PathToUnindexedFieldType();
$field->FieldURI->FieldURI = "calendar:IsAllDayEvent";
$field->CalendarItem = new EWSType_CalendarItemType();
$field->CalendarItem->IsAllDayEvent = true;
$change->Updates->SetItemField[] = $field;
$request->ItemChanges[] = $change;
$response = $ews->UpdateItem($request);
我在这里看到的最大区别是您使用$u->Updates->SetItemField = $setField;，而我的代码使用$u->Updates->SetItemField[] = $setField;。
我希望这能有所帮助。
编辑：您可能已经看到了这一点，但我的代码是基于php-ews-wiki中的代码。
我尝试了包括PathToExtendedFieldType在内的所有东西，但最终都不起作用。下面的代码对我来说是有效的
$ews = new ExchangeWebServices('red', 'red', 'red',ExchangeWebServices::VERSION_2007_SP1);
$request = new EWSType_UpdateItemType();
$request->SendMeetingInvitationsOrCancellations = 'SendToNone';
$request->MessageDisposition = 'SaveOnly';
$request->ConflictResolution = 'AlwaysOverwrite';
$request->ItemChanges = array();
// Build out item change request.
$change = new EWSType_ItemChangeType();
$change->ItemId = new EWSType_ItemIdType();
$change->ItemId->Id = $contact_id;
$change->ItemId->ChangeKey = $contact_change_key;
#$change->Updates = new EWSType_NonEmptyArrayOfItemChangeDescriptionsType();
#$change->Updates->SetItemField = array();
// Build the set item field object and set the item on it.
$field = new EWSType_SetItemFieldType();
$field->FieldURI = new EWSType_PathToUnindexedFieldType();
$field->FieldURI->FieldURI = "message:IsRead";
$field->Message = new EWSType_MessageType();
$field->Message->IsRead = true;
$change->Updates->SetItemField[] = $field;
$request->ItemChanges[] = $change;
$response = $ews->UpdateItem($request);
var_dump($response);
嗯，我不知道php中的情况如何，但在C#中还有另一个字段，必须设置：IsReadSpecified=true。
email.IsRead = true;
email.IsReadSpecified = true;
