Key learnings from peers

Valuable Features

Zimbra Collaboration offers centralized web-based management, seamless sync across devices, anti-spam tools, and integration with LDAP and Active Directory. Users appreciate the open-source flexibility, straightforward setup, simple migration, powerful web access, and shared folders. Features like document sharing, video conferencing, mobile apps, and automatic backup enhance its appeal. The platform scales easily, boasts excellent pricing, and supports ActiveSync for Outlook compatibility. The intuitive interface and customization options cater to various user needs effectively.
  • "Zimbra Collaboration has a good web interface."
  • "One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
  • "The configuration is simple."

Room for Improvement

Zimbra Collaboration faces challenges with security vulnerabilities and needs better spam filters. The software's patch management lacks reliability and thorough testing. Users find mobile access and administrative interface cumbersome. It's also criticized for inadequate storage management and lacking a desktop client. Integration with third-party tools is limited, and the tool's documentation is not widely accessible. Enhancements are required in video conferencing, push email functionality, and multi-cloud features. Performance and customization need improvement for streamlined operations.
  • "The solution’s forums don't have much information or documentation on administration tasks."
  • "Some issues cause the solution not to function correctly or to cause downtime once a month."
  • "The product must be more customizable."

Pricing

Zimbra Collaboration's pricing is perceived as more affordable than Microsoft Exchange, appealing to enterprises seeking low-cost solutions. Its open-source model offers flexibility, with both free community and paid network editions. Licensing is simpler and more cost-effective, catering to businesses with various needs. Although some regions find it expensive compared to Google Workspace, many appreciate its lower total cost, especially with negotiable terms for larger deployments. The solution supports both perpetual and annual licenses.
  • "The solution is competitively priced."
  • "We pay yearly licenses for Zimbra Collaboration."
  • "I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."

Popular Use Cases

Organizations primarily use Zimbra Collaboration for email communication and collaboration. It supports webmail, internal emails, and serves as an email server. Users also leverage it for document sharing, meetings, and managing calendars. Zimbra Collaboration caters to small to medium enterprises and educational institutions, providing unified communication with chat and calendaring features. Many use the on-premise or cloud version for its security and open-source capabilities, integrating it for sending emails, video conferencing, and storing files.

Service and Support

Customer service and support for Zimbra Collaboration vary. Larger enterprises find ticket-based forums inadequate, while local partners and the community provide additional assistance. Some report improvements in recent support experiences, especially with the network edition. The open-source support is less robust than the commercial version. Many users are satisfied with the responsiveness and expertise of the support team, but some suggest slow responses and limited familiarity with complex issues. Online communities are valuable for detailed information.

Deployment

Many found Zimbra Collaboration's initial setup straightforward and easy for those familiar with Linux. Some faced challenges without sufficient technical support, needing to learn independently. Installation time varied, with simple setups taking hours and complex ones days. Technical skills with command-line interfaces benefited deployments. A few mentioned difficulties due to multiple domains, while some rated installation ease moderately challenging but manageable. The setup process's complexity often depended on the organization's architecture and familiarity with Linux environments.

Scalability

Zimbra Collaboration offers robust scalability, suitable for small to large organizations. Users report ease in scaling from a few to thousands of accounts quickly. Challenges include ensuring high availability and planning for enterprise-level configurations. Many rate scalability highly, though some favor alternatives for very large deployments. It supports horizontal and vertical scaling and involves configurations that can require expertise. Zimbra is as scalable as competitors, with varying user capacities. Scalability ratings range from moderate to high.

Stability

Zimbra Collaboration demonstrates general stability with some variability. Users noticed improvements over time, with updates increasingly enhancing stability, minimizing crashes, and ensuring reliability. However, stability can vary based on version, with early releases sometimes facing challenges like high session numbers or infrastructure needs. Some users managed minor issues independently. Patches are provided to address bugs and vulnerabilities, such as Log4j, reinforcing its robustness. Stability ratings range from five to eight out of ten across different user experiences.

Deploys quickly and has a good web interface

Pros

"Zimbra Collaboration has a good web interface."

Cons

"The solution’s forums don't have much information or documentation on administration tasks."

What is most valuable?

Zimbra Collaboration has a good web interface.

What needs improvement?

When it comes to administration tasks like configuring specific filters or group signatures, I have to dig into the configuration since there's nothing in the graphical or web interface. The solution’s forums don't have much information or documentation on administration tasks. Open-Xchange has a much better administration interface.

Works efficiently for sending large file attachments and significantly enhances organizational communication

Pros

"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication. "

Cons

"They should enhance its online meeting features."

What is our primary use case?

We use the product for sending and receiving emails and sending and storing files in mobile storage.

What needs improvement?

They could provide a push email functionality for the enterprise version. We utilize SMTP to send emails to basic users for office usage. They could introduce a similar functionality for mobile usage as well.

They should enhance its online meeting features, particularly in comparison to robust platforms like Microsoft Office 365 Teams.

A good tool for messaging, collaboration, and sharing files that requires an easy installation process to get started

Pros

"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."

What is our primary use case?

I use Zimbra Collaboration. I provide support and integrate solutions to Zimbra.

What is most valuable?

Zimbra Collaboration is a good tool for video calls. It is also a good desktop application and mobile application, while Zimbra's two-factor authentication is not so good. The mobile application of Zimbra has features allowing it to be used in Zimbra Drive while also providing features for video calls.

Product version discussed: ZCS 8.0.9
Provides good email capability; lacking in security and performance

Pros

"Good email solution and it's open-source."

Cons

"There are some security issues."

What is our primary use case?

Just using ZCS 8.0.9 as email solution for about 60,000 users, with a big email data of 60 Tb (60,000 users * 1 Tb/user)

How has it helped my organization?

Security & performance issues (60,000 user):

- Don't support or guide how to integrate with MFA (Multi-factor Authentication)

- Backup & Recovery for 60 Tb email data is hard (60,000 users * 1 Tb/user); no effective solution for backup & recovery for such a case.

- Don't support DLP (Data Loss Prevention) solution.

- HA (High Availability): just support at the server (VMs) layer, don't support at the service layer.

- It is hard to upgrade ZCS 8.0.9 to ZCS 8.8.15 OSE .
