I am working on a Macbook Pro and would like to know if it is possible to force all calendar events to pop up in zimbra only? Currently, I have to accept the event, it goes to my iCal then I have to move it over to Zimbra. I would like to bypass the step of having all events go to iCal all together. I want to use Zimbra exclusively without the hassle of using iCal in addition. Could anyone please help?

Cheers

Matt
