can't synchronize calendar

[seromlig5]

I want to overwrite my Treo 600 calendar from iCal. It used to work but now new entries in iCal don't show up on the Treo, although new addresses in OS X Address Book do appear in my Treo Contacts, so I know data is being transferred. Does anybody have any ideas? Thanks.

I have a similar problem, but I use Entourage. New items entered on the Treo DateBook5 are transferred to the Entourage Calendar during hotsync, though sometimes some of their data is corrupted, (most often the appointment end-times,) but they are then deleted from the Treo. Usually I have to do an immediately subsequent hotsync and then the items are transferred back to the Treo, so they are now on both devices. Sometimes though, I first have to edit the item on Entourage in order for the Treo to apparently recognize that there is something new which needs to be synced. Weird, right? Anyone recommend the ideal Entourage/Treo sync solution? I'm currently using the Microsoft Entourage Conduit, which otherwise works pretty well, (tho I do sometimes have similar problems with contacts.) I haven't purchased MissingSync yet cause I'm not convinced it will solve my problems. Can anyone attest to it?
