Zimbra 8 Enhancements and Changes 

Jump To

On May 23rd, during the Friday night maintenance window, uTech staff will be upgrading the Zimbra mail system from version 7 to version 8. This is a major upgrade and will result in some noticeable changes to the Zimbra system.

There will be some changes to the look and feel of Zimbra. uTech has created a new default WIU theme. Other Zimbra themes, such as "Hot Rod" and "Lemongrass", will also be available as well as a few new ones specifically created for Zimbra 8.

Zimbra 8 has a simpler, cleaner look that will make it easier to navigate and use. Most of the features and tools are still there and the interface should not feel much different. It should not take long to become familiar with the new interface. Any impact to your email workflow should be minimal. 

The "Chat" feature that was in Zimbra 7 will not be available in version 8. Chat was a "beta" feature that never was officially supported by Zimbra. If the chat feature is important to you, please contact the Support Center. We can provide a different chat solution for you.

For further details on changes, please review the following.  If you have any questions about the Zimbra 8 upgrade, please contact the uTech Support Center at (309) 298-2704 or

Zimbra Web Client Serenity User Experience

  • Streamlined User Interface. The user interface has been completely redesigned with simplicity and ease of use being the key improvements. The Zimbra 8 interface is more streamlined so that common actions are easily discoverable and highly intuitive to use.
  • Conversation View. In Zimbra 8 email is presented to users in a “natural” conversation view that makes reading and replying to messages convenient and intuitive. Quoted text is hidden and messages are laid out in a way that is easy for users to understand the “in-reply-to” relationship between different messages in the same email thread. Discreet links to Reply, Forward and More Actions (presented just below the email) let users respond to messages quickly and efficiently.
  • Rich Composition. Improved composition editor allows users to craft rich text emails, with features such as paste-style support from desktop applications and the ability to include inline images bring the power of desktop word processors to email.
  • Shared Tagging. In Zimbra 8 tagging functionality has been improved so that when items are shared users cannot only use tags to organize their data but also share these tags across applications as well as mailboxes.

Activity Stream

Activity Stream allows users extensive control over the messages that go to their Inbox. Activity Stream is intended for low priority mail that the user will get to at a later time. Users can easily set up activity stream filters that direct incoming messages to various folders (or are deleted from) based on different criteria that they can specify. For example, emails to distribution lists, feed and notifications that are not directly addressed to the user can be archived in folders that can be read when convenient.

“Graymail” filtering prevents user’s Inbox from being cluttered by legitimate but unwanted emails.

Dedicated Search Tab

A dedicated search tab is created whenever a user enters a new query in the header search box. This allows users to perform a search, navigate away from the search tab to perform another action such as compose an email, or schedule an event and then come back to the search tab to continue with the query.

Zimbra 8 provides users with a simple yet powerful search interface allowing users to perform simple actions such as quickly filter on common attributes or perform complex search queries making use of complex logical operators.

Enterprise Calendaring

Zimbra 8 provides an intuitive and sophisticated enterprise calendaring system that enables users to manage multiple calendars and provides support for advanced scheduling activities.

  • experience improvements to time and resource suggestions. zimbra 8 has significantly improved the user’s experience when working with the appointment scheduling feature. once users select attendees, zimbra 8 can compare calendar availability and provide users with a list of suggested meeting times. similarly, based on meeting requirements such as the size of the room and location, zimbra’s scheduler can provide users with a list of conference facilities that fit meeting requirements.
  • merge and split views of “day” view gives users the flexibility to view their different calendars (e.g. personal and work-related) either individually or overlaid on top of each other. (in other words, see a “merged” view of appointments from several different calendars in one calendar.)
  • landscape and date range printing provides users greater control over how calendars are printed.
  • wizard to add external calendars when users right-click to create new calendars. zimbra 8 supports importing several popular calendar formats including google and yahoo! calendars.

Zimbra Mobile for ActiveSync 12.1 devices

Zimbra offers server side implementation of Microsoft’s ActiveSync 12.1 protocol providing end users access to their Zimbra mail on any mobile device that supports ActiveSync 12.1.

  • Auto-discover support enables seamless linkage between the user’s account on the Zimbra server and the email client on the mobile device when valid credentials (email and password) are supplied from the device.
  • Bandwidth Reduction Since most mobile devices are often on high latency, low bandwidth (reduced connectivity) networks, Zimbra’s ActiveSync implementation has been designed to operate at a reduced bandwidth.
  • Battery Optimization ActiveSync protocol implementation has been optimized to conserve battery life for push enabled devices.
  • Persona/Alias support ActiveSync implementation provides push synchronization of email, contacts, calendars, tasks as well as the Persona/ Alias profile configurations associated with the user’s email address.

  • Zimbra Instant Messaging (IM) capabilities was removed in ZCS 8.0.
