Outlook clients are supported via ActiveSync (Z-Push library) or the Kopano OL Extension (KOE), which serves as an enhancement to the already included ActiveSync. For video conferencing, the Kopano team has developed its own open source solution based on WebRTC: Kopano Meet offers end-to-end encryption and is available for Windows, macOS, Linux, Android, and iOS. Some of them can easily be integrated by plugins. Kopano interacts with many other platforms, applications, and services. Instead, it's a complete groupware solution and includes real-time communication in addition to the standard features of email, contacts, calendar, tasks, notes, and document editing. Unlike its predecessor, Kopano doesn't aim to be a mere replacement for Exchange.

Kopano, from the German-Dutch software manufacturer Kopano, is also AGPLv3-licensed and based on the Zarafa software stack.

The Community edition is free of charge and includes all grommunio features for up to five user accounts. For more information on the underlying architecture, please have a look at the manufacturer's website. grommunio uses a MySQL database for metadata only, while all "content" such as mail and groupware objects are stored in a per-user SQLite database. The flexible storage backend allows administrators to extend their setup by adding other servers or cloud accounts. Grommunio is designed for a very large number of users and-just like Exchange-supports database sharding (horizontal distribution of databases across multiple hosts). grommunio is also equipped with basic mobile device management (MDM).
For example, the developers have integrated Jitsi (video and audio telephony), Mattermost (chat), and file sharing and syncing ( ownCloud). Also included: Exchange ActiveSync for mobile devices and various standard protocols like CalDAV (calendar), CardDAV (address book), IMAP, POP3, SMTP, and LDAP, as well as Active Directory (for syncing of user accounts).Įxternal open source applications provide some features not supported by Microsoft's API or protocols.

grommunio works with various open source and proprietary mail clients, like Windows Mail, Outlook, Android, Apple Mail/iOS, Thunderbird, etc., and supports both the older RPC over HTTP protocol and the Outlook standard protocol MAPI over HTTP. Unlike Exchange, grommunio offers a mail server that's standards-compliant as well as a fully functional groupware solution with features like email, contacts, calendar, tasks, file sharing, and more. It is developed and supported by the Austrian company of the same name. Grommunio, formerly known as grammm, is published under the AGPLv3 license.
All candidates can either run on-prem or in the cloud. While grommunio, Kopano, Nextcloud, ownCloud, and the OX App Suite vary widely in functionality and are therefore attractive to different types of enterprises, they all provide free editions with the option to purchase paid support and add-ons. It's not just about becoming vendor-independent and reducing costs it's about using software with open standards and a different level of security-for the groupware server itself and the operating system behind it.Īll five alternatives in this article are Linux-based. In this article, I look at some open source alternatives and their advantages. However, many companies have concerns about storing their data in the Microsoft cloud. Since Exchange is closely integrated with Microsoft's Office products, users have access to a wide variety of productivity software and features, whether they're using a desktop or a mobile client.
This top dog dominates the corporate world, and the omnipresent Outlook mail client has become the de facto standard for groupware.
