Welcome to the technical documentation of Zextras Suite.

Here you can find a description of its functionalities and configuration options.

What is Zextras Suite?

Zextras Suite is an all-in-one solution that seamlessly integrate with Zimbra Open Source Edition, avoiding issues like conflicts with Zimbra.

Some strong points of Zextras Suite are: security (including encrypted communication channels, 2FA and SAML authentication), data protection and data ownership (you control your data: choose where to store data and backups, what to delete, and so on), full GDPR compliance.

Main Features & Components

Zextras Suite is organised in modules, that can be purchased in different bundles, according to the available licenses. More information on Zextras Store.

Modules can be individually enabled or disabled by an administrator. Instructions for this are provided within each module’s documentation.

Additional resources

Besides the individual modules, the Zextras ecosystem encompasses a customer support portal, and two additional portals: this technical documentation, and the Community.

On the customer support portal, dedicated to licenced users--i.e., existing customers and people who have started a trial—​one can open a ticket in case of problems with Zextras Suite or to report a bug. Non-licenced users can find help in the official forum (see the section below for more information).

The two technical and community documentation are more broadly described in the upcoming section.
