MAPI Logon fails (NT Service)

[Michael Zino]

Hi All,

I'm having problems with ex MAPI when its running from an NT service.

This is the code i'm running in the log on process.

Please... if you can see ANY problem, let me know....

void Logon(System::S tring* profile)

{

HRESULT hRes = -1;

LPVOID pMapiInit;

LPTSTR pprof;

FLAGS ntServiceMAPIFi eld = MAPI_NT_SERVICE ;

FLAGS mapiInitField = MAPI_NO_COINIT | MAPI_MULTITHREA D_NOTIFICATIONS ;

FLAGS mapiLogonFlags = MAPI_NEW_SESSIO N | MAPI_NO_MAIL | MAPI_EXTENDED |
MAPI_EXPLICIT_P ROFILE ;//| MAPI_PASSWORD_U I;

////////////////////////////////////////////////////////

// ***Important: Only if this module is a Service unmark the next 2 line.

mapiInitField |= ntServiceMAPIFi eld;

mapiLogonFlags |= ntServiceMAPIFi eld;

////////////////////////////////////////////////////////
MAPIINIT_0 MAPIINIT = { MAPI_INIT_VERSI ON, mapiInitField};

pMapiInit = &MAPIINIT;

if (FAILED(hRes = MAPIInitialize( pMapiInit)))

{

Marshal::ThrowE xceptionForHR(h Res);

}

pprof = (char*)Marshal: :StringToHGloba lAnsi(profile). ToPointer();

LPMAPISESSION __pin* pses = &m_pSes;

if (FAILED(hRes = MAPILogonEx((UL ONG)0, pprof, NULL, mapiLogonFlags, pses)))

{

Marshal::FreeHG lobal(pprof);

Marshal::ThrowE xceptionForHR(h Res);

}

m_pDefMsgStore = NULL;

Marshal::FreeHG lobal(pprof);

}

Regards,

Asaf

Michael,

What account is the service running under? By default, I believe that
the account runs over the LOCALSYSTEM (or LOCALSERVICE, I can't remember the
name) account. This account doesn't have access to the netowkr, so you
would have to have the service run under an account which does have access
to the network.

Hope this helps.
