Question

我使用以下代码获取IPM_SUBTREE下的所有文件夹。同样在所有计算机上工作正常。

但是，在其中一台客户机器中，这不起作用。在分析日志时，我们发现OpenProperty返回0x80004002

const GUID local_IID_IMAPITable = {0x00020301,0,0, {0xC0,0,0,0,0,0,0,0x46}}; 
hr = lpRootFolder->OpenProperty(    PR_CONTAINER_HIERARCHY, 
                            &local_IID_IMAPITable, 
                            0, 
                            0, 
                            (IUnknown**)&lpHierarchyTable);

以下是完整的代码

请改用lpRootFolder-＆gt; OpenHieirarchyTable（）。

“OpenProperty期间没有支持此类接口（0x80004002）”错误
