While working in previous organization, came across this web based product, specially due to its open source nature, and easier to learn. It helped a great deal in being up-to-date by tracking official mails.It has all the features that an basic web email client needs to have. Specially during the times we were connected to VPN, it used to easily work even in low or restricted network connectivity.It had easier and user-friendly User Interface, including refresh button, to force reload emails as per convenience.

1. Specially the optimized nature of it to work on limited or lower network connectivity like VPN, 2. Cost effective and Opensource nature.

User Interface was laggy sometimes. It has sort of older look and feel compared to other open source email collaboration products. Sometimes it was not able to filter junk mails effectively compared microsoft exchange service.

I think that Zimbra is a perfect tool for emailing and management. Despite some issues, it is very easy to implement the service and it helps to communicate with customers and colleagues in the handiest way.

To my mind, it is great that Zimbra gives an opportunity to share a calendar among colleagues and customers. It helps us to share all important data and meetings at any time. Another plus is a simple and user-friendly design. It is perfect both for qualified users and people who use it for the first time. And of course, emailing itself is on the top-level. It is easy to customize and make the necessary changes. Zimbra is an open source software with an opportunity to send emails, keep contacts, and make notes in the calendar. This service is perfect for remote work because I can keep an eye on everything and be sure, that everyone knows what they need to do.

I am convinced that Zimbra has more advantages than disadvantages. However, there are some issues to fix. Firstly, filters are hard to use and understand, because they aren’t flexible at all. Secondly, the software itself is quite hard to operate. Despite all pluses, the service still demands some basic IT skills. Thirdly, there might be some problems with data export and back up, because the software depends on servers.

Our organization is based on Linux with end user using the same and we really don;t want to go MS Exchange option so we left with choices of Lotus Notes (Which is a very good yet expensive product), Novell groupwise and Zimbra. Having tested Zimbra around more than 10 years ago we choose this. It has the flexibility to provide mobile base, thick client and thin web base client. So it was good choice and we are quite satisfied with our decision back then

Its scale-able, robust, secure and low cost. Based on Postfix and other opensource packages it provides good emailing solution. All the included packages are thoroughly tested before included in release. With most of the world going to cloud for email for the organizations need low cost yet secure and scale-able on premise mailing solution Zimbra is a good option. It has very good Web base UI which is very easy to use. There is no performance issues. Visibility with logs is very good . Zimlets are very cool features you can add on

The support is a bit so so maybe because of change of so many owners of the company. The web ui can use skin option to make it look and feel like different email platform in the market, e.g. if someone is use to outlook or gmail ui then a them/skin could provide that

Simply Zimbra Collaboration Suite is the best way to stay connected in the institution where I work. The planning of activities as well as the contact information of the different employees is centralized through this program. It is easier to communicate with the Zimbra Collaboration Suite.

The biggest advantage offered by Zimbra Collaboration Suite is the ability to communicate with other users by integrating various tools such as email, contact book, task planning and calendar in a single software and with a very simple interface.

Although Zimbra Collaboration Suite is a great software, sometimes it presents operating problems that are resolved by closing and opening the browser from where you work. Another aspect to improve is the design of the interface from the aesthetic point of view. It's simple but unattractive to look at.

1. Open Source - Easy to Configure, Less capital needed, less memory Consuming and Secure 2. simplicity - the user interface is very friendly no need to introduce people on how to use it. 3.

Stability

1. Can Include many functionalities and add ons. 2. Hard to configure shared mailboxes and DL's 3. Cannot handle huge data and less storage space 4. GUI can be much improved

* I agree with the following points: 1- The general presentation menu is quite friendly to the eye., as well as its versatility to be used in cell phones. 2- I like the easy installation and the web administrative console which can be used for many admin tasks. The Desktop app is great and easy to use.

* I agree with the following points: 1- Sometimes there are some glitches in Zimbra, but in most cases clearing cache and restarting browser helps to solve them. 2- Hard to customize the installation, lost data when I needed to migrate to another server. The API uses XML-RPC which is not easy to use, JSON is a lot easier.

Thanks to this software they have improved the relationships in our work team. Its diverse tools allow us to better plan our activities and keep us permanently communicated. Very good.

It is an economic software and very comfortable to work with. It is an easily accessible platform capable of integrating the most demanded requirements in an institution such as: mail, contacts, shared calendar and online documents. It is quite practical.

It is not the best option to integrate to mobile devices. I think it has several limitations when it comes to entering the Zimbra from a smart phone when compared to running on a desktop computer.

Thanks to Zimbra I have been able to keep better communication with my teammates and at the same time I have improved my ability to plan thanks to the tools that this software has. It has been a great alternative.

It has a very intuitive interface that makes this software an easy tool to use. In the same way its installation is very simple. Account with contacts, chat and tasks in addition to their email service. It is available for several platforms. It is accessible in terms of price

One aspect to improve is the interface design. I think it's somewhat antiquated if we compare it with other software of this type in the market.

A Personal and Work experience

It has been very adaptable to the needs of my company because it is open source It has been widely accepted by end users due to the application of web standards, which gives the user more reliability in the system. The administration interface has been very simple and functional when creating users, groups and requirements

The information filtering tools and emails have many details that have to be improved. The modules for the users themselves to change the password of their account have some problems.

It was decent, but outdated for any business that requires file transfers.

The email function was very easy to use, and it was simple to indicate when an email was high priority.

The date transfer abilities was awful. Files took ages to upload, and the account had a very limited quota which meant that you couldn't use it to store documents.

I am very impressed by the simplicity and reliability of Zimbra Collaboration Suite. I love the security Zimbra offers while still having the same look and feel of other familiar email clients. My team and I use Zimbra for email and scheduling meetings. It is very easy to use and an easy switch for any team looking for a more private solution to large teams wanting to collaborate via email. The themes are also a very nice feature (I use Carbon).

I can't think of any cons. It is a very simple email and calendar management system.

Great for small orgs that can't justify the cost of paid email suites but want the features that they may have become used to with Exchange/Outlook. The web app is pretty damned good, and the Zimbra Desktop app for Windows/Mac/etc is serviceable if you need to manage multiple accounts.

Requirement for extra apps on Android for CalDAV/CardDAV support as ActiveSync is only available in the paid (Network Edition).

This is a great software that makes collaboration a breeze!

This software is great for email and overall collaboration. It is easy to use and has helpful features. This is a great tool to keep up with our teams and makes collaboration a breeze.

I would like some more flexibility in the customization of the email. It is straight forward and simple but I would like to be able to customize a bit more.

Overall is was ok at the time. We made a much needed move to Mircosoft.

The desktop app was not bad, it did have some limitations. Syncing always seemed to take a while. It visually functions similar to outlook.

The add-ons and features were tricky to use. At the time, it did not have a mobile platform. The web version was clunky.

- searching is great (as I remember it can search even inside archives) - good localization - intuitive UI/UX

- complicated backup flow - lack of mails management rules - lack of features in the mobile version
