Get email addresses of outlook profile, MAPI

问题

How does one get the email addresses from an outlook profile, using MAPI, in C++ ? The code for start(works ok):

    HRESULT hRes = S_OK;
LPMAPISESSION  lpSession = NULL;    
LPMDB          lpMDB    = NULL;
LPMAPITABLE    lptMsgStores = NULL; 
LPMAPITABLE spTable = NULL;

std::wstring wProfileName;
std::wstring wUsername;

wUsername    = L"user1@mymail.com";
wProfileName = L"TestProfile";

// Initiate MAPI.
hRes = MAPIInitialize(0);


// Logon to Extended MAPI session.
hRes = MAPILogonEx(NULL, 
    (LPTSTR)wProfileName.c_str(),
    NULL,
    MAPI_EXTENDED | MAPI_EXPLICIT_PROFILE | MAPI_NEW_SESSION | MAPI_UNICODE | MAPI_LOGON_UI, &lpSession);

    if(FAILED(hRes))
    {
        MessageBox(NULL,L"logon error", L"",MB_OK);
    }

LPOLKACCOUNTMANAGER lpAcctMgr = NULL;
hRes = CoCreateInstance(CLSID_OlkAccountManager, 
    NULL,
    CLSCTX_INPROC_SERVER,
    IID_IOlkAccountManager, 
    (LPVOID*)&lpAcctMgr);

if(SUCCEEDED(hRes) && lpAcctMgr)
{
    CAccountHelper *pMyAcctHelper = new CAccountHelper((LPWSTR)wProfileName.c_str(), lpSession);
    if(pMyAcctHelper)
    {
        LPOLKACCOUNTHELPER lpAcctHelper = NULL;
        hRes = pMyAcctHelper->QueryInterface(IID_IOlkAccountHelper, (LPVOID*)&lpAcctHelper);
        if(SUCCEEDED(hRes) && lpAcctHelper)
        {
            LPOLKENUM lpAcctEnum = NULL;
            hRes = lpAcctMgr->EnumerateAccounts(&CLSID_OlkMail,
                NULL,
                OLK_ACCOUNT_NO_FLAGS,
                &lpAcctEnum); //THIS FAILS HERE, hRes != S_OK!
            _com_error err(hRes);
            LPCTSTR errMsg = err.ErrorMessage();
            wprintf(L"%s\n", errMsg);
            if(SUCCEEDED(hRes) && lpAcctEnum)
            {
                DWORD cAccounts = 0 ;
                hRes = lpAcctEnum->GetCount(&cAccounts);
                if(SUCCEEDED(hRes))
                {
                    hRes = lpAcctEnum->Reset();
                    if(SUCCEEDED(hRes))
                    {
                        DWORD i = 0;
                        for(i  = 0 ; i< cAccounts; i++)

回答1:

You don't add an email address to a profile, you add a service that may (POP3/IMAP4/SMTP) or may not (PST) expose or need an SMTP address. For POP3/IMAP4/SMTP addresses, use IOlkAccountManager API. You can play with it in OutlookSpy (click IOlkAccountManager button).

If you are using language other than C++ (or Delphi) that cannot use the IOlkAccountManager interface, you might want to look into Redemption and its RDOSession.Accounts collection
