Coming with Zimbra Collaboration 8.7 is an exciting new feature: two-factor authentication (also known as 2FA). Two-factor authentication is a technology that provides identification of users with the combination of two different components. These components may be something that the user knows (like a password, UserID, etc) and something that the user possesses (a good example can be a smartphone, or USB-key, etc.)

The use of two-factor authentication to prove your users’ identity is based on the premise that an unauthorized actor is unlikely to be able to supply both factors required for access. If, in an authentication attempt, at least one of the components is missing or incorrect, the user’s identity is not established with sufficient certainty and access to the user Zimbra Mailbox being protected by two-factor authentication remains blocked.

The future of collaboration, starts today

Zimbra has released Zimbra Collaboration 8.5. It is the first major Zimbra Collaboration release since Telligent acquired Zimbra from VMware last year.

New Feature Highlights

  • Touch client for tablets and smartphones: The secure, HTML5 mobile web application provides a device-specific user experience for Android and iOS devices. The Zimbra touch client can be tailored through open APIs and fully white labeled. It delivers anytime, anywhere mailbox access, through a unique Zimbra experience, that keeps people connected to their data.
  • Offline Web client: Offline Web client support for Chrome and Firefox keeps Zimbra users connected, even when not taking advantage of native HTML5 data storage support. Users get the ability to work offline with access to one month’s worth of data. And, IT administrators benefit from an offline client that doesn’t increase the cost or management associated with a full desktop client.
  • Exchange Web Services: The latest release adds new Exchange Web Services (EWS) support, enabling all mail, contacts, tasks and calendar functionality in Outlook for Mac. Administrators can add Outlook for Mac to the list of supported clients for BYOD environments, and users get to choose whatever Mac desktop client they prefer.
  • Zimbra Social integration: Zimbra Collaboration 8.5 includes integrated support for Zimbra Social. Customers running both Zimbra products benefit from a shared user experience and single sign-on. Keeping employees connected to all of the collaboration touch points.
  • Document preview: High fidelity document preview is now available, allowing users to preview documents in their Web browser.

Infrastructure Enhancements

  • Active-active: Active-active is part of a multi-release effort to increase Zimbra Collaboration’s scale and performance capabilities in complex Zimbra deployments. This encompasses a number of enhancements to the web application and server architecture, and introduces support for MariaDB. Zimbra Collaboration 9.x will continue this investment, helping eliminate downtime due to upgrades, maintenance or unplanned outages.

Feature Enhancements

  • Zimbra Connector for Microsoft Outlook (ZCO): The Zimbra Connector for Microsoft Outlook (ZCO) provides real-time, two-way syncing of mail, contacts, tasks and calendars between Outlook and Zimbra. The latest release adds support for traditional Chinese and improvements for system administrators including: syncing, connection security and share message support. Administrators can better support and troubleshoot issues with logging improvements. Users can now accept shared mail folders and calendars from Outlook without opening the Zimbra Web client and will notice improved performance when syncing a large number of messages.
  • ActiveSync Performance and Scalability Enhancements: Service providers running large-scale ActiveSync deployments will benefit from decreased computing resource costs and increased user density per server. Administrators can now add BlackBerry 10 devices to the list of ActiveSync-enabled devices that are supported for BYOD environments.
