I cannot seem to find a way to get Outlook 2007 to add my Zimbra Public calendar into outlook and have outlook subscribe to it so that it updates automatically.

When adding the Zimbra ics address to Internet Calendars in Outlook, Outlook says that the connection is "pending", & when I close Outlook and open it back up... the calendar that I attempted to add disappears.

Has anyone else had this issue? Is there a way to solve it?

Thanks ;D
