Beta - Universal UI

By: jdelacruz

The Universal UI is a Synacor Development to bring a new & modern HTML assets like SVG, CSS refactor, etc, but keeping all the SOAP API work which makes Zimbra the most complete and dense Web Client Experience of the Market.

Universal UI wants to remain almost intact all the Zimlet experience, so all Zimlets developed for ZCS 8.6/8.7 should work with it without problems.

Universal UI wants to achieve the goal to be responsive across all devices, from a 4K Screen to a Mobile Phone.

  • Version for Ubuntu 16.04 ? 

    By: gbarrelet on 2 weeks, 6 days ago for version 0.6


    Just tried to install on my Zimbra OSE 8.7.6 Ubuntu 14.04 edition.
    This platform is UBUNTU14_64
    Packages found: UBUNTU16_64
    This may or may not work.

    As this tool is still beta, I don't think that it will be a good thing to --platform-override.
    Your thoughts ?

    • This Release, as stated, is not intended to be installed in production at any case. It's only for testing purposes, for test Zimlets, etc. If you want to take a look, just fill this form, and you will receive user/pass http://info.zimbra.com/try-zimbra-universal-ui-public-cloud-beta Thank you for testing it!

  • Web Interface is unusable 

    By: lucascbeyeler on 4 weeks ago for version 0.5

    Yeah, after apply the correction, the web interface worked again, but It's not like the pictures posted here. It's just a recolor of the Harmony skin.

    It's strange this, because you are showing one thing in the pictures, but what the client see is another thing completely different.

    • The UniversalUI is still in the works, as you might read on the description, the look and feel it's like on the Screenshots, or it will be for Contacts and Calendar, for the Mail tab it's almost 97% already. Thank you for the feedback. And please keep trying it release after release. Best regards

  • Web Interface is unusable 

    By: lucascbeyeler on on 3/22/17 for version 0.5

    I installed inside a server this release, but the only thing that is working is the user login (just the screen). The admin crash and the error count skyrocket in the "element inspector", and the web client is bizarre to the point I can't even describe what's going on.

    Anyone can help me?

    • Hello, The Admin Console is a known issue, we are working on that for the next Release. You can use the CLI to create users, also you might like to force the new theme for all users, run the next commands:

      zmprov mc default zimbraPrefSkin harmony2

      zmprov mc default zimbraAvailableSkin harmony2
