I am using following code for querying interfaces.

HResult hr = MAPILogonEx ( NULL, (LPTSTR)lpcszProfile, (LPTSTR) Password,
        MAPI_EXTENDED|MAPI_UNICODE|MAPI_NEW_SESSION|MAPI_NO_MAIL|MAPI_TIMEOUT_SHORT,
&m_pSession );
CByteArray baEntryID;
LPMAPITABLE pMsgStoresTable;
hr = pSession->GetMsgStoresTable ( 0, &pMsgStoresTable );
bool bFoundEntryID = false;
if (SUCCEEDED ( hr ) )
{
    static const SizedSPropTagArray ( 3L, spta ) =
    { 3L, { PR_DISPLAY_NAME_A, PR_ENTRYID, PR_MDB_PROVIDER } };
    LPSRowSet lprs;
    hr = HrQueryAllRows ( pMsgStoresTable, (LPSPropTagArray) &spta, NULL, NULL,
0, &lprs );
    if ( SUCCEEDED ( hr ) )
    {
        //Hunt for the one of interest (or present dialog for user to choose)
        for ( ULONG nIdx = 0; nIdx < lprs->cRows && ! bFoundEntryID; nIdx++ )
        {
            SRow& ThisRow = lprs->aRow[nIdx];

            SPropValue& DisplayNameProp = ThisRow.lpProps[0];
            SPropValue& EntryIDProp = ThisRow.lpProps[1];
            SPropValue& ProviderIDProp = ThisRow.lpProps[2];

            LPSTR lpszDisplayName = DisplayNameProp.Value.lpszA;
            SBinary binEntryID = EntryIDProp.Value.bin;
            SBinary binProviderID = ProviderIDProp.Value.bin;
            //check the provider ID to see if it is MS-Exchange based
            if ( sizeof(GUID) == binProviderID.cb ) //
            {
                if ( 0 == memcmp ( binProviderID.lpb, pbExchangeProviderPrimaryUserGuid,
sizeof(GUID) ) ||
                    0 == memcmp ( binProviderID.lpb, pbExchangeProviderDelegateGuid,
sizeof(GUID) ) ||
                    0 == memcmp ( binProviderID.lpb, pbExchangeProviderPublicGuid,
sizeof(GUID) ) ||
                    0 == memcmp ( binProviderID.lpb, pbExchangeProviderXportGuid,
sizeof(GUID) ) )
                {
                    baEntryID.SetSize ( binEntryID.cb );
                    CopyMemory ( baEntryID.GetData(), binEntryID.lpb, binEntryID.cb );
                    bFoundEntryID = true;
                }
            }
        }
    }
}
if (bFoundEntryID)
{
    LPMDB pMsgStore = NULL;
    hr = m_pSession->OpenMsgStore ( NULL, baEntryID.GetSize(), (LPENTRYID)
baEntryID.GetData(),
            &IID_IMsgStore, MDB_NO_DIALOG|MDB_NO_MAIL, &pMsgStore );
    if ( (SUCCEEDED ( m_hr )) || ( m_hr == MAPI_W_ERRORS_RETURNED && pMsgStore)
)
    {
        hr = pMsgStore->QueryInterface(IID_IExchangeManageStore4, (void **)
&m_pExMgStore);
        // here I get E_NOINTERFACE  
    }
}

I am using outlook 2007 profile and ESMMDB32.dll of version 12.0.6211.1000.

Please help me to resolve this problem of IID_IExchangeManageStore4.  

Thanks in advanced
