我一直在使用的代码片段是：

System.setProperty("javax.net.ssl.trustStore","C:\\Users\\vermad\\Downloads\\Softz\\jssecacerts");
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
ExchangeCredentials credentials = new WebCredentials("username.domain.com","password");
service.setCredentials(credentials);
service.setUrl(new URI("https:/domain/EWS/Exchange.asmx"));
ItemView view = new ItemView (5);
FindItemsResults<Item> findResults = service.findItems(WellKnownFolderName.Inbox, view);
for(Item item : findResults.getItems()){
    item.load(new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.MimeContent));
    System.out.println("id==========" + item.getId());
}

System.setProperty（“javax.net.ssl.trustStore”，“C:\\Users\\vermad\\Downloads\\Softz\\jssecacerts”）；
ExchangeService服务=新的ExchangeService（ExchangeVersion.Exchange2010_SP2）；
ExchangeCredentials credentials=新的WebCredentials（“username.domain.com”，“password”）；
服务。设置凭据（凭据）；
setUrl（新的URI（“https:/domain/EWS/Exchange.asmx”）；
ItemView视图=新的ItemView（5）；
FindItemsResults findResults=service.findItems（WellKnownFolderName.Inbox，视图）；
对于（项：findResults.getItems（））{
load（新属性集（BasePropertySet.FirstClassProperties，ItemSchema.MimeContent））；
System.out.println（“id=====”+item.getId（））；
}

Hi Dharmesh，你找到这个错误的原因了吗？你是如何解决的。当没有解决方案可以帮助任何人解决这个问题时，为什么这个问题被投3票？
