我正在使用 FindItem 调用从 Exchange Web 服务 (EWS) 获取项目（约会）。获取的属性是项目 ID 和 EffectiveRights。EffectiveRights 属性通常不包含正确的值。但是，有时值是正确的（使用相同的代码），但我不知道是什么原因造成的。
我正在搜索的日历文件夹被委派给我进行身份验证的服务用户的作者权限，并且它包含该服务用户是其作者的约会。
我正在使用ews-java-api库，响应跟踪表明这不是解析错误。
用于检索项目的代码：
ItemView view = new ItemView(100);
PropertySet propertySet = new PropertySet();
propertySet.add(ItemSchema.Id);
propertySet.add(ItemSchema.EffectiveRights);
view.setPropertySet(propertySet);
FolderId folderId = new FolderId(WellKnownFolderName.Calendar, Mailbox.getMailboxFromString(targetSmtpAddress));
FindItemsResults<Item> items = service.findItems(folderId, filter, view);
Item firstItem = items.getItems().get(0);
firstItem.getEffectiveRights(); // Returns NONE, READ. This is incorrect.
Item bindItem = Item.bind(service, firstItem.getId()); //
bindItem.getEffectiveRights(); // Returns NONE, READ, MODIFY, DELETE. This is correct.
