ServiceResponseException:在商店中找不到指定的对象

Question

我正在尝试升级使用WebDAV对Exchange 2003的应用程序返回responseXML,然后在SalesForce CRM上创建案例(使用Web服务wsdl)并将来自电子邮件的附件放在案例上.

我们正在迁移到Exchange 2010 SP2,因此我需要使用EWS访问收件箱.

我收到ServiceResponseException错误"在商店中找不到指定的对象."

这是我的代码:

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);// .Exchange2007_SP1);

List<SearchFilter> searchFilterCollection = new List<SearchFilter>();

searchFilterCollection.Add(new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false)));
searchFilterCollection.Add(new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.HasAttachments,true)));
SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.Or, searchFilterCollection.ToArray());

//creates an object that will represent the desired mailbox
Mailbox mb = new Mailbox(@"bbtest@domain");

ItemView view = new ItemView(1);

//creates a folder object that will point to inbox folder
FolderId fid = new FolderId(WellKnownFolderName.Inbox, mb);

service.Url = new Uri("https://domain/EWS/Exchange.asmx");

//this will bind the mailbox you're looking for using your service instance
Microsoft.Exchange.WebServices.Data.Folder inbox = Microsoft.Exchange.WebServices.Data.Folder.Bind(service, fid);

FindItemsResults<Item> results = service.FindItems(WellKnownFolderName.Inbox, searchFilter, view);

foreach (EmailMessage email in results)
{
    Debug.Print(email.From.ToString());
    Debug.Print(email.DisplayTo);
    Debug.Print(email.Subject);
    }

它会抛出这一行的错误:

Microsoft.Exchange.WebServices.Data.Folder inbox = Microsoft.Exchange.WebServices.Data.Folder.Bind(service, fid);

我做错了什么,我该怎么办呢？

另外,有没有办法让EWS返回与webDAV类似的XML responseStream？

根据我的经验,当您无权访问Exchange存储中的对象时,可以返回NotFound.确保您使用的任何凭据都具有对目标MB的完全邮箱访问权限.(我想如果你想要做的只是阅读项目,你可能需要更少的权限,但如果需要你可以稍后修改.)我没有看到你在上面设置任何凭据,所以你可能正在使用你的访问EWS默认信用,即您在运行时记录的内容.

不,你不能从EWS获得WebDAV响应流:它们是完全不同的服务,并且我相信你知道,在E2007之后WebDAV不存在.
