That internally uses item jobs as well IIRC.

No, that won't work. While not cancelling the tasks keeps it the active 
context, it also keeps your custom task from being executed.

However, since the purpose of custom task right here seems to be calling 
retrieveGALItems() asynchronously you could do that with 
QMetaObject::invokeMethod().

retrieveItems()
{
   ...
   scheduleCustomTask("retrieveGALItems")
   // Don't cancelTask() , just return.
   QMetaObject::invokeMethod(this, "retrieveGALItems", Qt::QueuedConnection);
}

retrieveGALItems()
{
   ...
   fetch 300 items from Exchange
   itemsRetrievedIncremental(items);
   if (no more items) {
      itemsRetrievalDone();
   } else {
       // go around again.
      QMetaObject::invokeMethod(this, "retrieveGALItems", 
Qt::QueuedConnection);
   }
}

Cheers,
Kevin
