April 16th, 2019 by

Dear EGroupware Users,

Outlook CalDav Synchronizer synchronizes events and contacts between Outlook and EGroupware. Supported Outlook versions are 2019, 2016, 2013, 2010 and 2007. The Outlook CalDav Synchronizer is Free and Open-Source Software (FOSS). You can find and contribute to the source code on github.

Collabora 4.0 and Outlook CalDAV Sync-Client

March 1st, 2019 by

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.

EGroupware Security Update 16.1 & Upgrade to 17.1

November 6th, 2017 by

Dear EGroupware users,

we would like to inform you about the following news:
1. EGroupware security update and bug fix release for versions 16.1 & 17.1 RC
2. EGroupware 17.1 is coming soon.

1. EGroupware Penetration Tests / Code Review / Security Update for 16.1 and 17.1 RC

Marcel Mangold from SySS GmbH plus the whole EGroupware development team spent three days digging through our codebase in search of possible vulnerabilities. Three intensive days with lots of insight into how an attacker thinks and works.

We were able to identify some attack vectors, with our knowledge of the EGroupware codebase combined with Marcels pen testing knowhow.
It proved that the EGroupware security architecture on multiple levels – including our eTemplate system – is already quite good, but we’ll of course continue to improve it and already solved the problems we found with this security release.

We have provided a security and bugfix update for EGroupware.
Especially with regard to security updates, we strongly recommend updating your EGroupware systems.

We do not provide an update for version 11.1 and 14.1 and recommend an update to version 16 or 17.
The security update has already been automatically installed for all customers in the EGroupware hosting of EGroupware GmbH. You are already safe and don’t have to do anything.

2. New  EGroupware version 17.1 is coming soon

Collaboration makes work easier and can save your team a lot of time.
The new function “Collaborative Editing” with Collabora online office and other new functions of the EGroupware will be presented in our webinar on Thursday, 9th of November 2017. (only in german language). The new EGroupware version 17.1 is coming soon. We will inform you about the exact time schedule and how to update to the new version in the next weeks.

Kind regards

Optimised Operational Concept for the EGroupware Hosting

March 24th, 2017 by

Dear EGroupware users,

Quite a bit has happened during the last weeks. As already announced, the whole hosting cloud infrastructure moved to the German data centre provider Profitbricks.

New Data centre and optimised Operational Concept

The move is successfully completed, all instances are now running in the new data center in Frankfurt/Main, Germany.  After an extensive research and talks to different providers, we decided to work with Profitbricks as an experienced, German cloud computing supplier. We’re happy to present you the new operational concept for more reliability today.


  1. Data storage takes place in Frankfurt in two independent storages in different fire compartments on several hard drives.
  2. Servers are virtualised and will be automatically started on new hardware in case of a hardware failure.
  3. Servers can be equipped with more ressources anytime during operation (e.g. storage, CPUs).
  4. The EGroupware hosting farm runs under the open-source system “Kubernetes”. It manages the orchestration of the containers. The hosting farm itself communicates with a “Galera” database cluster and the “NFS” server for files.
  5. Daily database backups and snapshots of the files are automatically created and saved for at least 30 days. This means, if you accidentially delete files, they can be restored.
The standards of Profitbricks and EGroupware guarantee an extended stability and failure safety for all EGroupware hosting customers.

Technical Setup of the Hosting:

Permanent Replication of all data in a second data centre in a different location

To offer even more failure safety, EGroupware now additionally runs in a second Profitbricks data centre in Karlsruhe, Germany. All EGroupware data is consistently replicated (files every 15 minutes) and stored in this second data centre. In case of a service failure in Frankfurt, hosting customers can hence access their latest data in Karlsruhe. In this case, we’ll automatically activate a reading access to your data. Should there be a longer service failure, we now also have the option to enable the backup hosting farm as a primary platform. Even in case of a longer regional interruption, we can therefore react quickly and make all your data available.

Our Graphic explains the functionality of the new operational concept:

Testing of the Backup Hosting Farm:

To test your EGroupware data, stored in the backup farm, you can access it with this URL anytime: „instance name – top-level“.

For example for our support centre instead of “”: „“ or “” for all “.net” domains. In case of a service failure, the switch from the primary hosting farm to the backup hosting farm takes place automatically.

Preview – Move of the Mail Server:

The scheduled move of the EGroupware mail farm to the data centre of Profitbricks will take place by the end of June. We’ll also establish a replication of all mail data in both data centres. Therefore we’ll also achieve an improvement of spam filtering and virus protection. Customers of the EGroupware mail hosting will be informed about this process in a separate e-mail.
Kind regards
Birgit Becker, EGroupware GmbH

EGroupware hosting receives A+ rating from SSL LABS!

November 9th, 2016 by

EGroupware hosting again receives A+ rating concerning security from SSL LABS!

SSL LABS is testing the ssl setup of domains and gives a top rating to EGroupware.

We updated the EGroupware hosting to be even more secure and high-performance:

  • HTTP Strict Transport Security (HSTS) prevents a downgrade to insecure HTTP. It allows web servers to declare that web browsers should only interact with it using secure HTTPS connections, and never via the insecure HTTP protocol. Read more about security with HSTS: Wikipedia HTTP Strict Transport Security
  • Updated Ciphers for more robust Forward Secrecy. Forward Secrecy protects past sessions against future compromises of secret keys or passwords. Read more about forward secrecy: Wikipedia Forward Secrecy
  • HTTP/2 is now enabled on all EGroupware domains. HTTP/2 is a major revision of the HTTP network protocol. Read more about HTTP/2: Wikipedia HTTP/2
