我使用Exchange Web服务调用GetRoomLists,我们正在运行Exchange 2010.以下代码正在通过控制台应用程序执行.根据“无错误”的
XML响应,调用成功,但不返回任何数据.当您尝试通过Outlook约会添加一个时,我们列出了几百个房间,因此不确定为什么会发生这种情况.
我已尝试使用EWS DLL版本1.2和2.0,使用默认凭据或传入凭据.我注意到在最初发布之后,响应标题显示我们正在使用Exchange 2012 SP2,因此我尝试更新我的代码以使用该ExchangeVersion枚举值,但结果没有变化.
我已成功在此Exchange服务器上使用EWS来读取邮箱,但之前从未使用过房间.
C#
ExchangeService es = new ExchangeService(ExchangeVersion.Exchange2010);
es.TraceFlags = TraceFlags.EwsResponse | TraceFlags.EwsRequest;
es.TraceEnabled = true;
es.UseDefaultCredentials = true;
es.AutodiscoverUrl("autodiscover@example.com");
//this collection is empty after processing
EmailAddressCollection eac = es.GetRoomLists();

解决方法
好吧,我找到了原因/解决方案.令人困惑的是,GetRoomLists不返回房间列表,而是返回房间列表或“房间列表”集合的列表.这些是包含房间列表的特殊类型的分发列表.
如此处所述,http://social.msdn.microsoft.com/Forums/en-US/exchangesvrdevelopment/thread/4ff04c60-48c2-4a69-ab75-2383e73bfde2,您需要设置房间列表,或者需要查询AD并检查msExchRecipientDisplayType属性以跟踪房间.
此链接显示了如何将LDAP查询写入返回房间的示例：http://social.msdn.microsoft.com/Forums/en-US/exchangesvrdevelopment/thread/e2d10953-a8f9-459c-8a0e-f10c2e568b26
代码我放在一起寻找房间：
private List<string> GetConfRooms(string filter)
{
List<string> sRooms = new List<string>();
DirectoryEntry deDomain = System.DirectoryServices.ActiveDirectory.Domain.GetComputerDomain().GetDirectoryEntry();
DirectorySearcher dsRooms = new DirectorySearcher(deDomain);
dsRooms.Filter = string.Format("(&(&(&(mailNickname={0}*)(objectcategory=person)(objectclass=user)(msExchRecipientDisplayType=7))))",filter);
dsRooms.PropertiesToLoad.Add("sn");
dsRooms.PropertiesToLoad.Add("mail");
foreach (SearchResult sr in dsRooms.FindAll())
{
sRooms.Add(sr.Properties["mail"][0].ToString());
}
return sRooms;
}
