- MAPI_UNICODE
lppMAPIError
[out] A pointer to a pointer to the returned MAPIERROR structure that contains version, component, and context information for the error. The lppMAPIError parameter can be set to NULL if there is no MAPIERROR structure to return.
Return Value

Remarks
The IMsgServiceAdmin::GetLastError method retrieves information about the last error that was returned by an IMsgServiceAdmin method call. Clients can provide their users with detailed information about the error by including this information in a dialog box.
Notes to Callers
You can make use of the MAPIERROR structure, if MAPI supplies one, pointed to by the lppMAPIError parameter only if GetLastError returns S_OK. Sometimes MAPI cannot determine what the last error was or has nothing more to report about the error. In this situation, GetLastError returns a pointer to NULL in lppMAPIError instead.
