Collabora 4.0 and Outlook CalDAV Sync-Client

Dear EGroupware Users,

in February the schedule was already quite full and right at the beginning of the year there were two exciting events. At the Univention Summit EGroupware was silver sponsor and at the CalConnect chief developer Ralf Becker and community manager Stefan Unverricht were able to make new contacts. In our February newsletter we would like to keep you informed about the latest developments at EGroupware.

Collabora Online 4.0 released

Collabora Online 4.0 was released on 14 February 2019. Further information can be found below in the newsletter.

This release includes a new look, mobile improvements, improved interoperability, new dialogs and features, as well as a number of bug fixes and other improvements. Collabora Online 4.0 will soon be available in EGroupware Hosting and also for self-installations.

Collaboration with the developer of the CalDAV Synchronizer for Outlook

Having established contact in December 2018, EGroupware GmbH started cooperation with Alexander Nimmervoll of Generalize-IT Solutions OG at CalConnect. Soon there will be a purchase version of CalDAV Synchronizer for Outlook “supported” for EGroupware. With the CalDAV Synchronizer you can synchronize address book and calendar data between EGroupware and common Outlook versions.

Contrary to the freely available version, the purchase version ensures that EGrouware is tested regularly and that reported errors are corrected. If you are interested, please contact us directly. More detailed information will soon be available on our website.

EGroupware 19.1

The new EGroupware 19.1 will be released shortly. The most important new features are:

  • Optimization for GDPR Address book policies and admin history support the implementation of the basic data protection regulation.
  • Communicate via Rocket.Chat: Integration of Rocket.Chat including screen transmission and video chat. Rocket.Chat is an open source team chat platform that allows you to communicate securely and easily in real time with other people within ECroupware. is the leading open source alternative to proprietary chat tools like Slack, Microsoft Team, Hipchat or Stride and extremely user-friendly.
  • Improved user interface: Modern theme with colored icons and increased use of avatars (users can assign a photo or graphic to their profile).

  • Improvement of various EGroupware functionalities, for example the possibility to edit comments in the ticket system afterwards, color design in the ticket system according to subject area, category or version.
