Zimbra Collaboration Reviews

Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization. Zimbrais easy to manage.

The calendar is a quite useful organizational tool. We also created a lot of accounts for special needs, since we can have as many as we want.

There are some bugs we found that could be fixed. Also, there was a chat tool which was really useful, but was discontinued.

We’ve used Zimbra for 4 years.

We did not encounter any issues with stability.

Regarding scalability, from a user point-of-view, gmail is more convenient with all the other tools, such as Google Docs, Google Drive, etc.

We did not use any other solutions.

To complete the initial setup, you need to adjust the spam filter, setup DKIM, etc. Also, it’s Linux-based, so you need to be familiar with that environment.

The free version is good enough for a small to medium size company.

We evaluated Gmail before going with Zimbra.

If you don’t have a technical person to manage the project, you may want to use a different solution.

I work mainly with webmail. On the web, we have more than 10,000 accounts on our server

It is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions.

We can control all the data in my IT infrastructure.

• Shared folders
• Mobile synchronization
• Admin tools
• Anti-spam tools
• Webmail is simple and powerful.

• Online documents edition
• File sharing permissions with Nextcloud integration
• More features for the open source edition
• Native HA for more virtualization platforms, like Proxmox

More than five years.

Email in Zimbra:

The email application allows users to activate the Zimlets "request read receipt". For me, it's a brand new and useful support for email services, which I have not yet experienced elsewhere.

Besides, the interface is very convenient for busy people while scanning the incoming messages/emails and at the same time opening them (3 specific columns/areas of the main "Mail" tab).

Despite sticking with Gmail for over a decade in terms of business, Zimbra have impressed me with some other aspects as well... If the time comes, I would prefer Zimbra to my current solution.

Zimbra mail reminds me of Hotmail, which I did employ in the past. And comparing it to other email free services like Yahoo, Gmail, etc., Zimbra is still on the way to getting in touch with a wider audience, such as: employers, employees, educators, officers, etc., because it has been a symbol of the open-source community and such a powerful resource for students and educators to explore further, as well as to contribute. 

Calendar, tasks in Zimbra:

Different than other applications I have been using for these functions, namely: calendar, tasks, document, etc. Zimbra simply saves time, as these are attached to the main interface by a tab instead of a link to a different page. So, it's recommended for businessmen, especially.

Server deployment and the GUI for emails should be better.

I have used it for a few months.

From the server side: the installation/deployment should be more user-friendly.

Zimbra Collaboration can be used as an email server.

Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available.

The solution could improve by making it easier to use.

I have been using Zimbra Collaboration for approximately six years.

The solution is stable.

The solution is scalable. However, all the mailbox details are stored in MySQL or MongoDB. If it is an enterprise-level configuration, then we need to plan for the high availability. This is another challenge in Zimbra. If those things were fixed, then it will be really a good solution.

Zimbra Collaboration has online support communities that are very good at providing detailed information.

I have used Microsoft Exchange.

The installation is not difficult. However, initially, management will be difficult but once you have used it for a while you will not find any challenges.

I rate  Zimbra Collaborationseven out of ten.

The Zimbra Collaboration Server has many pros that are useful in a business. It has a centralized web based interface for managing the server console. A user can easily use it as a web based & app base on their desktop, laptop, i-phone and smart phone. An inside user console user can send mail, chat, video call, and voice call with other people. You are able to create a centralized address book on a server so that anyone can import and export contacts on their account. Sync facilities make it easier for all your device data updates. Additionally, you can set your G-mail, yahoo, and Hotmail accounts to import their addresses as well. Anti-spam, antivirus, and directory services can integrate with the server. Like LDAP, and Active Directory… you can design polices with the help of a class of service (CoS) for end user features like quota and storage. The search over internet facility is also included with the latest version of Zimbra.

There can be difficulties resolving problems on the server side when problems arise. Before installation, you have to resolve all dependencies, otherwise it is very difficult to setup the server.
