We have been having this problem for a while now, and RIM don't seem to be giving much help on this subject. When we are connecting a blackberry to a laptop to synchronise contacts, addressbook etc from Microsoft Outlook, the Intelesync program crashes and you are then unable to reconnect to the software to continue with the syncronisation. At the moment we are using a crude work around for this problem, all we do at the moment is reset all the syncronise items and then turn these items back on to the synchronise list. This seems to do the trick but only for a limited time and then we are back to square one again. I have also tried updating the software to the latest version but this still hasn't made any difference.
