如何连接到Exchange服务器并从共享邮箱(非我自己的“myname@mycompany.com”)读取邮件。

到目前为止,这是我的代码:

//Create a service
        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
        //Autodiscover end point
        service.AutodiscoverUrl("someaddress@mycompany.com");


        FindFoldersResults folderSearchResults = service.FindFolders(WellKnownFolderName.Inbox, new FolderView(int.MaxValue));

        Microsoft.Exchange.WebServices.Data.Folder exchangeMailbox = folderSearchResults.Folders.ToList().Find(
            f => f.DisplayName.Equals("NameOfSharedMailboxIwant", StringComparison.CurrentCultureIgnoreCase));

        //Set the number of items we can deal with at anyone time.
        ItemView itemView = new ItemView(int.MaxValue);

        foreach (Microsoft.Exchange.WebServices.Data.Folder folderFromSearchResults in folderSearchResults.Folders)
        {
            if (folderFromSearchResults.DisplayName.Equals("NameOfSharedMailboxIWant", StringComparison.OrdinalIgnoreCase))
            {
                Microsoft.Exchange.WebServices.Data.Folder boundFolder = 
                        Microsoft.Exchange.WebServices.Data.Folder.Bind(service, folderFromSearchResults.Id);

                SearchFilter unreadSearchFilter =
                    new SearchFilter.SearchFilterCollection(
                        LogicalOperator.And, new SearchFilter.IsEqualTo(
                            EmailMessageSchema.IsRead, false));

                //Find the unread messages in the email folder.
                FindItemsResults<Item> unreadMessages = boundFolder.FindItems(unreadSearchFilter, itemView);

                foreach (EmailMessage message in unreadMessages)
                {
                    message.Load();

                   Console.WriteLine(message.Subject);


               }    
                }

当我运行此操作时,我会抛出一个异常,说明“SMTP地址没有与之关联的邮箱”:

 Microsoft.Exchange.WebServices.Data.Folder exchangeMailbox = folderSearchResults.Folders.ToList().Find(
            f => f.DisplayName.Equals("BA", StringComparison.CurrentCultureIgnoreCase));

我错过了什么?我觉得我几乎在那里,这应该根据EWS Managed API 2.0文档工作,但我

答案 0 :(得分:20)

您应该只使用FolderId重载来指定要访问的邮箱。例如,如果您的共享邮箱名为Shared@domain.com,则使用

FolderId SharedMailbox = new FolderId(WellKnownFolderName.Inbox,"Shared@domain.com");
ItemView itemView = new ItemView(1000);
service.FindItems(SharedMailbox,itemView);

也不要使用

ItemView itemView = new ItemView(int.MaxValue);

这不起作用,因为Exchange会限制因限制而返回的最大项目数。始终将findItems和find文件夹的结果分页,请参阅http://blogs.msdn.com/b/exchangedev/archive/2010/03/12/throttling-policies-and-the-ewsfindcountlimit.aspx
