Hello gfator24, My first post here – I have the same problem on my VZW 8130. The Desktop Manager application on both my home and office PCs skip right over the calendar sync. Both had worked well until recently. Long story short – RIM technical support advised me last Friday (Nov 23, 2007) this is a known problem which has appeared in the past few days. They have no solution yet but are working on it. It is definitely in the phone, not in the DM application. In addition, the phone would spontaneously deleted hundreds of my calendar entries (I have about 2000 – lots of history). My free memory is typically 8MB but sometimes drops to zero.

BTW: Neither reinstalling DM nor updating the service books has corrected the problem. I haven’t tried re-flashing the phone yet but I’d imagine the problem would reappear anyway. RIM will email me when they have a solution. I will post it here.
