I'm sorry to have to post this as the answer is probably out there somewhere, but I've been banging my head on this problem for far too many days now. I haven't been able to find instructions anywhere, and I give up.
We have ZCS 5.05 and I'm running the 5.05 isync connector. (version 5.0.2201). Mac OS X 10.5 Leopard, Entourage 2008.
I initially got Entourage working with isync, and Entourage sync services were enabled, the Entourage integration was enabled in the isync connector, the entourage ical calendar was created and it was sorta working for the most part, but the zimbra helper and sync services processes were running wild on the computer, spiking 100% CPU and basically making the computer unusable.
Then I discovered that it was better to do calendar syncing with calDAV instead, and so I went back into the connector and set up caldav, and it did everything in ical and I can see everything there and that's great, and Entourage integration is enabled, but what am I supposed to do now? Am I supposed to turn sync services back on in Entourage? That doesn't strike me as making any sense, as that will then create a new calendar in ical that won't actually be pulling any data from the server, right?
Is there a step-by-step guide on setting up Entourage, Leopard, isync and everything else to make this all work correctly? Or is there anyone out there that can explain it to me? I'd really love to be able to use Entourage, but this whole process is confusing the living hell out of me.
