Key features

Zarafa WebApp


  1. Shared folders and calendar overlay support
    The calendar provides multi-user weekly calendaring and advanced delegation. Secretaries and management benefit from delegation and sharing options that set WebApp apart from other web-enabled clients.
  2. Fast user interface and loading time
    Thanks to smart caching and HTML5, the experience is akin to a fat client. The heavier processing of index results and searches is done by the backend.
  3. Efficient user context actions
    WebApp’s interface is designed with 'frequently used features' that are instantly available and located exactly where the user expects them to be.
  4. Plug-ins like chat and web meetings
    WebApp and its plug-ins deliver smooth integration with other communication applications. Plug-ins vary from chat and web meetings to other integrations available in the community.

Collaboration plug-ins catalysed by open innovation

The computer might evolve into nothing more than a terminal to your online applications and operating system.

WebApp is an expansion platform for plug-ins. The underlying WebApp platform enables developers to develop plug-ins after only one hour of web training. Therefore, organizations that use WebApp will benefit from a rapid feature sequence from user-driven innovations. Open Source in combination with Zarafa's inclusion in many distributions empowers the WebApp platform to be one of the leading collaboration platforms in the world. Users already benefit from Facebook and Google+ plug-ins and an attachment preview option developed via open innovation.
