I (unfortunately) have to use MS Exchange at work for email and calendaring, and would like to ship the calendar to my Zimbra server holding my personal email - the end result is shipping the calendar and addressbook to my iPhone.
I have the Address Book syncing working just fine, but I cannot get the Calendar connector to sync my calendar. Right now I have a Macbook running Leopard and Entourage 2004, talking to an Exchange 2003 server. I have installed the connector off my Zimbra 5.0.10 server. Unfortunately, in the connector under the Advanced tab, 'Entourage integration' is greyed out.
