"Most Zimbra users only see the user side of Zimbra but I can tell you that the admin side is quite impressive. After upgrading, be sure to login to the Admin Console to enable any desired new features as many of them are off by default and configurable on a Class of Service basis. If you would like to give different users access to different feature or combinations of features, create additional Class of Service types, configure them as desired, and then assign your users to the appropriate COS.
"The Zimbra Admin Console has gotten a major upgrade with this release. The interface is now multi-windowed within a single browser window..."
