MAPI GetOutgoingQueue not supported on Windows Mobile (so the Outbox?)

  • 项目

Recently I had to work on a sample code based on my previous post around MAPI that shows a possible way to extract the BODY of the mails in the Inbox folder of the ActiveSync account… this time I needed to grab a handle of the Outbox folder, and therefore I had to modify the function SaveMessagesFromStore of that post. Luckily the code was modularized enough… smile_regular so, once I had the LPMAPIFOLDER pointer to the Outbox I could continue using basically the same code. I thought there was a MAPI Function similar to IMsgStore::GetReceiveFolder, but found that quite many functions are not implemented in Windows Mobile 6 – see doc here. Luckily MAPI gives different ways to reach a goal, and in this particular case the code was based on the PR_IPM_OUTBOX_ENTRYID property of the MAPI store:

         // Get the Outbox folder
        ULONG rgTags[] = {1, PR_IPM_OUTBOX_ENTRYID};
        LPSPropValue rgprops = NULL;
        ULONG ulValues = 0;
        hr = pStore->GetProps((LPSPropTagArray) rgTags, MAPI_UNICODE, &ulValues, &rgprops);
        CHR(hr);
        
        cbEntryId = rgprops[0].Value.bin.cb;
        pEntryId = (LPENTRYID)rgprops[0].Value.bin.lpb;
        
        // We have the entryid of the Outbox folder, let's get the folder 
        hr = pStore->OpenEntry(cbEntryId, pEntryId, NULL, 0, &ulObjType, (LPUNKNOWN*)&pFolder); 
        CHR(hr); 
        
        //check 
        CBR(ulObjType == MAPI_FOLDER);
