issue with icloud sync to outlook 2007

Hi all

I am currently trialling the Norton Security 22.0.  Looks pretty good so far except that my iCloud calendar and contacts do not sync with my Outlook anymore - not unless I logout of iCloud, delete all the stuff on my laptop and then reinstate iCloud on my laptop.  What an enormous hassle. The reason I dropped Zone Alarm and am trialling other programs is exactly this problem.

I understand there might be something about setting ports in the Firewall but goodness knows I can find where or how one is to do that. 

My trial expires in 9 days - if I don't find a way of getting this work then I'm afraid I'll move on to another program yet again.

 

Thanks
