That internally uses item jobs as well IIRC.

No, that won't work. While not cancelling the tasks keeps it the active=20
context, it also keeps your custom task from being executed.

However, since the purpose of custom task right here seems to be calling=20
retrieveGALItems() asynchronously you could do that with=20
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",=20
Qt::QueuedConnection);
   }
}

Cheers,
Kevin
