1. OpenMsgStore fails in Exchange 2000

Hello all,

I am trying to access messages on Exchange 2000 Information Store. I
logged on to server as Administrator but OpenMsgStore () fails saying
" You do not have permission to log on - Microsoft Exchange Server
Information Store".

What may be the problem ?

Please help.

WinMain ( ....)
{
    ULONG cbDefStoreEid = 0;
    LPENTRYID pDefStoreEid = NULL;
    HRESULT hRes;
    LPMAPISESSION pSession = NULL;
    LPMDB pDefMsgStore = NULL;
    LPMAPIERROR a;

    hRes = MAPIInitialize(NULL);

    hRes = MAPILogonEx(0,    // Handle to parent window
          "MS Exchange Settings", // Profile name
          NULL,   // Password
          MAPI_NEW_SESSION |
          MAPI_EXTENDED |
          MAPI_LOGON_UI, // Logon flags
          &pSession);  // Resulting MAPI session

    // Find default message store
    hRes = HrMAPIFindDefaultMsgStore(pSession, &cbDefStoreEid,
&pDefStoreEid);

    hRes = pSession->OpenMsgStore(0, cbDefStoreEid, pDefStoreEid,
NULL, MDB_NO_DIALOG | MAPI_BEST_ACCESS, &pDefMsgStore);

    pSession->GetLastError ( hRes, 0, &a ) ;
    // returns error code as " You do not have permission to log on
    // Microsoft Exchange Server Information Store
