We have Redtail Hosted Email (Zimbra) and Redtail CRM. If we add a meeting to our Zimbra Calendar it doesn't Sync with the CRM calender and vice versa. I guess we didn't do our research enough because it seemed logical to us for Redtail Email and Retail CRM to sync the calendar. We don't use Outlook on our desktops so the Zimbra Outlook Connector wouldn't work for us. Thanks!
