How To Resolve Ambiguous Names with the Outlook Object Model Using Visual C++ (260626)

MORE INFORMATION

To resolve duplicate names programmatically, you must have another method of identifying each recipient (other than the recipient's name).

The following sample subroutine uses each recipient's e-mail address to confirm the selection of the duplicate recipients. You can also use any other information that you have for each recipient if the data corresponds with the properties that are provided in the OOM.

void AmbiguousNameRes()
{
   RecipientPtr MyRecipient;
   AddressListsPtr spAdrLsts;
   AddressListPtr spAdrLst;
   AddressEntriesPtr spAdrEnts;
   AddressEntryPtr spAdrEnt;

   // Ambiguous name resolution technique.
   _ApplicationPtr objOutlook("Outlook.Application.9");
   _NameSpacePtr objNameSpace = objOutlook->GetNamespace("MAPI");
   MyRecipient = objNameSpace->CreateRecipient(_bstr_t("Recipient Name"));
   MyRecipient->Resolve();
   if (MyRecipient->Resolved == FALSE) { // failed due to 0 or >1 matches
      spAdrLsts = objNameSpace->GetAddressLists();
      for (long i = 1; i < spAdrLsts->GetCount(); i++) {
         spAdrLst = spAdrLsts->Item(i);
         spAdrEnts = spAdrLst->GetAddressEntries();
         for (long j = 1; j < spAdrEnts->GetCount(); j++) {
            spAdrEnt = spAdrEnts->Item(j);
            if (spAdrEnt->GetName() == MyRecipient->GetName()) {
               // Determine if correct name.
               if (spAdrEnt->GetAddress() == 
                   _bstr_t("Recipient@EmailAddress")) {
                  MyRecipient->AddressEntry = spAdrEnt;
                  MyRecipient->Resolve();
                  if (MyRecipient->Resolved == TRUE) {
                     // Have valid recipient object.
                  }
                  else {
                     // Try other properties?
                  }
               }
            }
            spAdrEnt = NULL;
         }
         spAdrEnts = NULL;
         spAdrLst = NULL;
      }
      spAdrLsts = NULL;
      objNameSpace = NULL;
      objOutlook = NULL;
   }
