Exchange EWS SearchMailboxes无效的子元素错误

Question

我有一个奇怪的错误。当我尝试执行SearchMailboxes时，我收到此错误：

未处理的异常：Microsoft.Exchange.WebServices.Data.ServiceResponseException：请求＆＃34;：//schemas.microsoft.com/exchange/services/2006/types"具有无效的子元素＆＃39; ExtendedAttributes＆＃39;

问题是我在某些电脑上遇到这个错误。使用fiddler，我可以看到我的电脑发送没有节点ExtendedAttributes and it works的请求。

This is the ExtendedAttributes node that produces the error.

代码：

        List<MailboxSearchScope> scopeList = new List<MailboxSearchScope>();
        foreach (SearchableMailbox mb in searchableMailboxes)
        {
            MailboxSearchScope scope = new MailboxSearchScope(mb.ReferenceId, MailboxSearchLocation.All);
            scopeList.Add(scope);
        }

        MailboxQuery query = new MailboxQuery(searchQuery, scopeList.ToArray());

        MailboxQuery[] mbQueryList = new MailboxQuery[] { query };
        SearchMailboxesParameters p = new SearchMailboxesParameters
        {
            SearchQueries = mbQueryList,
            ResultType = SearchResultType.PreviewOnly
        };

        ServiceResponseCollection<SearchMailboxesResponse> res = _service.SearchMailboxes(p);

ExtendedAttributes是Exchange 2013 SP1中引入的新元素，仅供内部使用。

我在您的代码中没有看到您尝试使用此元素，因此我建议您在实例化ExchangeService对象时指定ExchangeVersion.Exchange2013。
