Can't Sync Contacts and Calendar -- Look Here

Question

Ok, to quell the confusion on this issue let me fix the general errors with this so others here can see why this is caused and how to fix it.
First if you cannot sync contacts and calendar and only those two items check your hotsync log. And look for contacts and calendar if you do not see these items this means you have an exchange server setup on the device or did at one point. To fix this go into email(Versamail) and tap on your account name in the top left then go to accounts and account setup. Once in here check all your accounts by clicking on them and then hitting edit. Look for EAS or only one server address. If this is what you have you are syncing to exchange and Versamail takes over contacts and calendar from hotsync. This cannot be changed. If you do not have EAS or one server on the device. It is possible that Versamail is holding the contacts and calendar due to you had exchange before. If this is the case the only thing you can do is a hard reset to resolve the issue. I understand that most cannot backup there data(contacts and calendar). But to fix this issue you will need to do the hard reset.
If you are not using exchange and find contacts and calendar in your hotsync log but have OLERR under them please look at this KB for possible fixes to this issue. http://kb.palm.com/SRVS/NUA/launchKB.asp?c=31167
Lastly if you are using Verizon's WirelessSync. Just by having this installed will disable contacts and calendar from syncing. To enable this go into WirelessSync then settings-->advanced settings and enable other sync applications.

I'm having this issue, but can't find any issues with an Exchange server (I don't work in a big office, and we don't have one set up).  My phone did a hard reset this past weekend when I tried to send a picture via Snappermail (which I use instead of Versamail, if it matters); I was able ot restore all my data with the next hotsync, but, after that, it stopped syncing the Contacts and Callendar (but the hotsync log shows no errors--although it also doesn't say htey synchronized correctly, either).  I've tried doing what was suggested in the first post of this thread (to the best of my ability--as I don't use Versamail, I just tried to do the same thing with Snapper, and made sure no accounts were up on Versamail).  I've also uninstalled and reinstalled the Desktop, and performed a hard reset on my Treo.  Still, nothing.  I'd backed up the contacts and addresses on my memory card with FileZ, and that's the only place I've got the current info--I somehow lost the separate back-up I'd created on my desktop (outside of my Palm folder) for my contacts, although the datebook info is still there.  I'm using Vista, and running Desktop 6.2.2.  Any help or suggestions would be appreciated immensely--I've lost a few nights sleep trying to get this figured out, and am at the end of my rope.  Thanks!
