I agree from a users point of view it is so much better than Plus but from an admin point of view not as friendly, not as adaptable, really bad field mapping, not enough data being uploaded, no grouping, lack of searching requirements, updating users is on an individual basis not by group as there aren't any groups. Just uploaded all our staff and the default quota is 50mb so have had to go into each one individually and changed it. If we had the front end of Zimbra and the backend of Plus it would be so much better. Also getting hassle as there is no synchronisation between it and PDAs/Blackberrys so it looks like Zimbra needs to be open for emails, and Outlook to synchornise calendars. If there was a link between Outlook and Zimbra that would make life so much easier too.
