A fews weeks ago my Treo 650 stopped syncing with my iBook. I have been scouring forums, knowledge bases, and even tried contacting customer support but so far no solution. I'm hoping someone out there can help.

I am running Entourage X (Service Release 1), syncing with Missing Sync (5.1.2) and the Microsoft Entourage Conduit (10.4.1). When I sync (using USB/cable), the sync seems to hang on "Synchronizing Date Book" and ultimately fails with the error message "The connection between your handheld computer and the desktop was lost. Some of your data was not backed up. Please check your setup and try again." I then have to "Force Quit" the Missing Sync application on my laptop.

The Contacts, Notes and Tasks seems to have synced, but not the Calendar.

I have tried uninstalling/reinstalling all the related software - Palm OS, Missing Sync and Microsoft Entourage conduit. I have rebuilt the Entourage database (at the suggestion of the Missing Sync support rep who said since this involves the Microsoft conduit they don't support it). I've run "dbScan" on my Treo. I even trashed the "Entourage Storage file" as described onthe Microsoft page (http://www.microsoft.com/mac/otherpr...S5_Tshoot.xml).

So far nothing seems to work. Does anyone have any ideas?

I AM SO FRUSTRATED I"M READY TO THROW THIS THING OUT THE WINDOW!!!
