Open-source email and collaboration suite that pairs an email and calendar server with a web client for messaging, contacts, and file sharing.
Zimbra is a collaborative software suite that combines an email and calendar server with a full-featured web client. First released as Zimbra, Inc. in 2005, it provides email, group calendars, contacts, document sharing, chat, and videoconferencing through a single platform.
Zimbra is offered in two main editions. The Open Source Edition makes most components available under open-source licenses, while the Network Edition is a commercially supported release that adds closed-source components such as connectors for Outlook calendar and contact synchronization. The server runs on Linux and supports standard protocols including IMAP, POP3, CalDAV, CardDAV, and SMTP.
In 2015, Synacor acquired Zimbra, continuing to develop the suite for service providers, enterprises, and government organizations that want an alternative email and collaboration platform.
MSPs and internal IT teams use Zimbra for Zimbra Collaboration (Network Edition), Zimbra Collaboration (Open Source Edition), Zimbra Web Client.
Best for: teams that need business, collaboration, or line-of-business software.
Zimbra pricing depends on your organization's size, the modules you enable, and your contract term. Tools in this category are usually licensed by subscription, billed per user, per month, and scale with the users, endpoints, or sites you cover.
Public rate cards are not always available, and many vendors set final pricing through a quote or their MSP and reseller channel. To get an accurate Zimbra price for your environment, request a quote from Zimbra directly, or ask a managed IT provider that supports Zimbra to bundle licensing, deployment, and management into one predictable monthly cost.
