Treo 650 & Entourage won't sync calendar!

I've read all the posts all over the net. I still can't get Entourage to pick up the calendar on my Treo 650.

I have Palm Software 4.21
OSX 10.4.7
Latest update to office 2004 (11.2.5)
No conduit conflicts
Name on Palm hotsync, entourage & treo are the same.

What else can I do?

Help!!

TIA

Use GoBetween from PocketMac (Google it), that is what I use, hope this helps.

Thanks. I was hoping for a fix without having to buy any 3rd party software.
It seems that I have no other choice though...

I am running the same software and I have no problem syncing Entourage and my Cingular Treo 650, including the calendar.
