Zextras Suite is an all-in-one solution that integrates easily with Zimbra Open Source Edition, avoiding concerns such as Zimbra conflicts.

Security (including encrypted communication channels, 2FA, and SAML authentication), data protection and data ownership (you own your data: pick where to keep data and backups, what to delete, and so on), and full GDPR compliance are some of Zextras Suite’s strong features.

Zextras Suite is divided into modules, which may be purchased in various packages based on the available licences. Zextras Store details.

  • Zextras Auth is the authentication layer that handles login modalities as well as mailbox and other module access.
  • Zextras Backup is largely concerned with solutions for saving your mail, documents, and data. The module also includes Restore Strategies for recovering lost objects or accounts, as well as Advanced Backup Techniques such as Disaster Recovery.
  • Zextras Mobile manages mobile devices’ access to the address book, shared resources, and Zextras modules.
  • Zextras Powerstore includes sophisticated storage management principles and methodologies.
  • Zextras Admin describes sophisticated administration tasks.
  • Zextras Drive is used to exchange draughts, entire papers, movies, and any other type of content with all of your coworkers.
  • Zextras Docs is a collaborative editing environment for documents, spreadsheets, presentations, and other types of files.
  • Zextras Team is a full-fledged communication solution that allows for chat, videoconferencing, and remote presentations.
  • An administrator can enable or disable modules separately. The documentation for each module has instructions for doing so.
supplementary resources

Apart from the various modules, the Zextras ecosystem includes a customer service portal as well as two more portals: this technical documentation and the Community.

On the customer support site for licenced users–that is, existing customers and persons who have begun a trial–one may file a ticket in case of Zextras Suite difficulties or to report a bug. Non-licensed users can seek assistance on the official forum (for more details, see the section Community below).

The next section goes into further detail on the technical and community documents.

Users and Documentation Types
This documentation (docs) is divided into sections and is hosted on It is supplemented by the online Community Documentation for Zextras Suite. While they are open to anyone, they are aimed at particular audiences. The typical Zextras Suite user falls into one of two categories: Administrators or regular users.
This guide concisely defines the Web GUI and the functions provided by Zextras Suite; it demonstrates how to activate and configure the modules, as well as how to perform typical administrative activities.
  • Docs is mostly intended for administrators and includes the following sections:
  • Zextras Suite compatibility with Zimbra versions
  • Installation instructions for Zextras Suite, including system requirements and configuration advice
  • Each module has its own handbook.
  • Quick and comprehensive command reference. A list of all CLI commands that may be used to manage the module is supplied at the conclusion of each module. Each command has a link to its complete documentation, which contains all accessible options and command examples. A separate CLI section also contains fast and extensive CLI references.
  • Since 3.0.0, changelogs are accessible for all releases.
The community is divided into numerous sections; its main strength is a big collection of articles, which is supplemented by the official discussion forum, where community members communicate, look for relevant resources, offer feedback, share their experiences, and comment on articles. Furthermore, non-licensed users can utilise the forum to seek assistance and support.
This site’s material is organised into categories, where visitors may discover instructions, how-tos, and more general information regarding the functions.
More specifically, the articles concerning Zextras Suite and Zimbra 9 OSE are organised as follows:
  • The blog, which includes release notes, news, and other information
  • Administrators should read the Admin Guides.
  • The User Guides are intended for Regular Users, that is, anybody who utilises Zextras Suite and its features but does not require access to administrative functions and setups.
An Administrator, in addition to utilising Zextras Suite, maintains its installation, access permissions, configuration, and so on. Administrators can discover information on this documentation as well as the Community. The following is a selection of some of the most relevant resources:

Theme Zextras for the Zimbra Webclient
The Zextras Theme for the Zimbra WebClient is a stylish UI theme for Zimbra Network Edition and Zimbra Open Source Edition.
It works with both Zimbra 8 (8.6 and above) and Zimbra 9.
The Zextras Theme is included in Zextras Suite starting with version 3.1.5, therefore users of Zextras Suite will just need to upgrade their software to get the theme.
Users of Zimbra Network Edition and Zimbra Open Source Edition who are not also Zextras Suite users can freely download the theme from and manually install it by following the instructions below.
Installation Instructions
The theme will be downloaded and installed by the Zextras Suite installer.
Additionally, by following these easy procedures, the theme may be manually downloaded and installed on all supported Zimbra Open Source Edition and Zimbra Network Edition versions:
  • Download the package for your distribution from the Zextras website.
  • Transfer the package to your server.
  • Unpack it with tar zxvf zextras-theme-*.tgz.
  • cd zextras-theme-installer &&./ as root
  • Once the installation is complete, restart the mailboxd service by typing su – zimbra -c ‘zmmailboxdctl restart’ into the command prompt.
Activating the theme
Users will be able to find the Zextras Theme in their account Preferences under “Appearance” after installing it.
Select the “Zextras” entry, save, and accept the reload when requested.
Services and service management Services Each Zextras Suite module is made up of many “services,” each of which provides a unique set of capabilities.
All modules include at least the module service, which rules the whole module: halting the service will stop the module, and disabling the service’s auto-start will prevent the entire module from being loaded when the mailboxd service begins.
The following module commands can be used to control service management services using the Zextras CLI:
  • getServices – returns a list of all services and their current state.
  • doStartService [serviceName] – launches the serviceName.
  • doStopService [serviceName] – terminates the service.The name service
  • doRestartService [serviceName] – This function restarts the service.The name service
The getServices command will display if the module is active and whether it may be started or terminated, for example:
If a service cannot be launched, the getServices command will provide the following information:
These are the services that are provided for each module. The same sub-commands as seen in the preceding example are available for each service (i.e. could_not_start_because, could_start, could_stop, running).
How to Report a Problem
The most effective technique to report a Zextras Suite issue is the one that helps both the Reporter and the Technical Support Team to achieve their mutual goal—the issue’s resolution!—in the quickest and most robust manner.
The most important starting point is to prepare an accurate and complete report that describes the issue you encountered and attach it to the bug report or ticket that you are opening, because in these cases, the Technical Support Team can immediately look into the issue without the need to ask for more information. Creating such a report may necessitate running commands, taking pictures, describing the procedures to duplicate the problem, and so on. This section explains how to find out more about Zextras Suite and its modules.
Step-by-step instructions
Please follow these steps to report a Zextras Suite issue:
  • Examine the relevant portions of the Technical Documentation (ensure you choose the proper version of your Zextras installation) to see if you can discover any valuable advice. 
  • Look through the Community to see if there are any articles that cover a solution to your problem. 
  • Check to verify if what you’re reporting is a software issue (see Definition of “issue”).
  • Collect all of the information listed on this page in the What information to include in your report section.
  • Create a case in the Zextras Support Portal at, including as much detail as possible.
The term “issue” is defined as
While you, as a user, may encounter a variety of issues, the Technical Support Team may not be able to assist you in all of them.
In some instances, the Technical Support Team will be unable to assist you:
  • Licencing complaints: While we strive to provide the most equitable licencing model possible, we recognise that we cannot please every consumer on the planet. If you believe that the Zextras Licencing does not meet your needs and would want to share your thoughts, please contact the Sales Team using the form found at
  • Problems with older versions of Zextras Suite: To provide a better service, technical help is restricted to the most recent Zextras Suite version. If you are not using the most recent version, please upgrade Zextras Suite; if the problem persists, please proceed with your complaint as instructed in the rest of this page.
  • Hardware issue: If the server on which Zextras is installed does not function properly, the Technical Support team will be unable to assist. However, you can refer to Zimbra’s tweaking Guidelines for optimisations and tweaking alternatives.
  • In these instances, the Technical Support Team will be happy to assist:
  • Suggestions for new features: We at Zextras are always interested in hearing what new features our users would like to see in Zextras Suite. If you have a suggestion for a new feature, please submit it to the Technical Support team via the Support Portal
  • Configuration or customisation not applied: the majority of tickets fall into this category, such as an account not receiving e-mails while being (seemingly) correctly setup; the custom corporate logo not appearing on the login site, etc.
Tools for the job
The following tools will undoubtedly be useful in obtaining the information required to register a bug report:
  • A method to view logfiles on your Zimbra server (less after SSH access would suffice) 
  • Dev Mode on the Zimbra Web Client
  • Dev Tools in your browser (Web Developer in Firefox, Developer Tools in Chrome)
  • Log level management in Zextras Suite
When encountering an issue, set both the Log Level and Notification Level to Debug under the Core tab of the Zimbra Administration Console to obtain relevant insights from the log files.
After increasing the Log and Notification Levels and login into Dev Mode in Zimbra 8.x or later, the Zimbra Administration Console may become stuck during page loading.
When this occurs, the Zimbra DoS filter is most likely limiting access owing to the large number of connections made in Debug Mode. Please see the dedicated Zimbra DoS Filter section for more information on it, its options, and how to tune them for faster loading.
What data should you include in your report?
Depending on the Zextras module in question, you should include various information in your report, the majority of which is available as CLI command output. In order to issue these tasks, you must have console or SSH access to the mailserver.
Attach all of the information given in the ticket-common-information_title to each Support Portal ticket you open. You may then proceed to the relevant area, which is dedicated to each Zextras module, and gain further information.
Set the mailbox’s verbosity before recreating the problem.To debug a log file, use the command zxsuite config global set attribute ZxCore_LogLevel value 0. To prevent overflowing the disc with logs, return it to 1 after the process is complete.
Please assist us in improving Zextras Suite.
In the “Core” area of the Zextras Administration Zimlet, a checkbox for “Send full error data to Zextras to help us improve Zextras Suite” is accessible. This will help us to improve Zextras Suite by collecting a broader collection of error data, which may include:
  • Error messages and stacktraces in their entirety.
  • Email addresses are a type of address.
  • Brand, model, and ID of a mobile phone.
  • Headers and contents of messages.
This data will be processed by automated processes and used strictly for bug hunting and software analysis.
This capability may also be enabled by setting the ZxCore_SendFullErrorReports Zextras Core property to TRUE.
