My Blackberry 9930 is no longer syncing up with the Outlook Calendar or New Contacts

It used to work fine. Calendar appointments emailed to me DO snyc up with the Blackberry but NOT the ones I enter into Outlook 2010 32 bit at my desktop. This problem just recently started and has never previously been a problem. Changing settings on my BB and deleting data does NOT seem to help.

If I loaded Blackberry Desktop Software onto my DESKTOP with Outlook (not a tablet) and connected it to the 9930, could this be the problem? It wants me to turn OFF wireless sync, but this seems counter-intuitive because this is actually what I want - WIRELESS SYNC??
