Question

访问Exchange 2010 SP2中的另一个邮箱时（我获得了其文件夹的所有者权限，通过创建/修改/删除收件箱上的用户权限来检查OUT OUTOOK）。

现在，如果我通过EWS尝试相同的事情，我只会得到“访问被拒绝。检查凭据并重试。”。现在，我实际上使用与outlook相同的凭据（Windows Auth），使用以下代码：

        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);            

        service.UseDefaultCredentials = true;

        service.PreAuthenticate = true;

        service.AutodiscoverUrl(<myUser_with_rights>);

        FolderView view = new FolderView(50);

        view.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);
        view.PropertySet.Add(FolderSchema.DisplayName);

        SearchFilter searchFilter = new SearchFilter.IsGreaterThan(FolderSchema.TotalCount, 0);

        view.Traversal = FolderTraversal.Shallow;

        FolderId InboxId = new FolderId(WellKnownFolderName.MsgFolderRoot, <emailAddressOfOtherMailbox>);
        findFolderResults = service.FindFolders(InboxId, view);

        foreach (Microsoft.Exchange.WebServices.Data.Folder myFolder in findFolderResults.Folders)
        {                
                myFolder.Load();
                PropertySet propSet = new PropertySet(BasePropertySet.FirstClassProperties, FolderSchema.Permissions);
                Microsoft.Exchange.WebServices.Data.Folder fo = Microsoft.Exchange.WebServices.Data.Folder.Bind(service, myFolder.Id, propSet);

                fo.Permissions.Add(new UserId(<email>,<permission>));
                fo.Update();//<-----Exception occurs
        }

没有尝试更新哪个文件夹/节点更新，它总是失败。读取权限的工作正好。

有没有人有想法？
