MAPISession :: OpenEntry的MAPI_E_UNKNOWN_ENTRYID错误 [英] MAPI_E_UNKNOWN_ENTRYID error for MAPISession:: OpenEntry

问题描述

我编写了一个函数，它将MAPI会话作为参数并返回IMAPIProp接口。我使用了API MAPISession :: QueryIdentity和MAPISession :: OpenEntry。但是，对于MAPISession :: OpenEntry，我收到错误0x80040201（MAPI_E_UNKNOWN_ENTRYID）。

I have written a function which takes a MAPI session as parameter and returns IMAPIProp interface. I have used the APIs MAPISession::QueryIdentity and MAPISession:: OpenEntry. However, for MAPISession:: OpenEntry I am getting the error 0x80040201 (MAPI_E_UNKNOWN_ENTRYID). Can anyone please let me know the reason for this error?

推荐答案

错误 表示在 lpEntryID 参数中传递的条目标识符是无法识别的格式。如果包含该对象的服务提供者未打开，则通常会返回此值。地址簿

The error tells that the entry identifier passed in the lpEntryID parameter is in an unrecognizable format. This value is typically returned if the service provider that contains the object is not open. Similar query for addressbook is available @ http://support.microsoft.com/kb/174394. You can try the same approach & let me know how it goes.
