With Zimbra it has been easier to encourage collaboration with different teams and team members. More experienced team members who need or desire the muscles of Outlook and easily set Zimbra in Outlook. Pros Ok lets begin with the good. Zimbra is a suite that comes with the basic calendar, contact list and the ability to create tasks. It allows you to set reminders, tasks and appointments and share them with coworkers quickly. This is perhaps the best features of this software. It is a relatively simple program without all the bells and whistles of the beast known as Outlook. It is the simplicity of this software and security that makes it ideal for our company. We have just migrated to Zimbra and the roll out for the most part was successful. One thing I absolutely love about Zimbra is the ability to set it up in Outlook. This gives me the collaboration within my team using Zimbra and the features I've come to love in Outlook. Cons If you are use to the larger and more powerful collaboration suite known as Office 365, you'll be a bit disappointed with Zimbra. Zimbra is not going to search for you, talk for you or keep your emails forever. What you'll find is a simple program that allows you to collaborate with your coworkers and management without the bells and whistles. It can be a disappointment if you're use to a larger suite. Communication is limited to just responding to an email, and emails are set to a 30 day retention limit. You can use a "Zimlet" to capture and save emails however. As stated above being able to incorporate Zimbra into Outlook is a way to overcome some of the limitations of Zimbra.

The migration of content was a bit more difficult due to the nature of our old system, practically nothing supports GroupWise, so we had to migrate one account at a time via IMAP from the old server to the new server. Pros It is based on Linux, it can do SSO sign-on with Active Directory, as well as most LDAP based authentication directory services. The web mail is full featured, not a light client. They provide both ActiveSync and CalDAV/CardDAV access, which is important for us as a design company using mostly Mac computers. Cons The software itself is great. My only issue was for the few times I needed to reach out to Zimbra/Synacor's support, the response time was a bit slow (1-2 days). I assume if this had been an outage and had called in rather than only email my request, I would've received a faster response. Alternatives considered [OX App Suite](https://www.capterra.com/p/58368/OX-App-Suite/)[IceWarp](https://www.capterra.com/p/159920/IceWarp/) Reason for choosing Zimbra Collaboration Suite It is the product that integrated the best with macOS's native mail and calendar client. It is also based on open source technology (i.e., only the web front-end is proprietary, but all the engines/services powering it are open source software (Postfix, Amavis, SpamAssassin, etc).

Director Education Management Used the software for: 1-2 years ### "Zimbra pros and cons" January 28, 2025 3.0 Pros We used Zimbra in our institution for a few years as a secure main site for emails and virtual meetings. What I like the most about it is that it is comprehensive and offers calendars, contacts, tasks and tools for collaboration. Cons As we used Zimbra in a school environment it did not feel very user friendly and was a little difficult to operate. Administratively, it was more expensive than other available suites for schools. Review Source Giridhar S. Campaign Executive Information Technology and Services Used the software for: 2+ years ### "Best Email Client Software" March 25, 2019 5.0 Zimbra, an instant mail setup client which is the best for the corporate sector as we can easily deliver messages and receive the same which works in real time. I have been using Zimbra mail server from the past 2 years and it works remain excellent till time as I don't even have any late deliverability nor any delayed task on it. The features were actually well built for an employee who used to use this on a daily basis and can interact with their colleagues/staff members/clients easily and on time. Pros The most I like in Zimbra is: 1. Faster Deliverability of Emails in real time 2. Can add Email Signature to all our emails 3. Can send Events/Meetings Invites 4. User Responsive in design and lite speed software 5. Can use Out of Office option if you're in leave and send automatic responsive email to them 6. Can Import/Backup all emails/contacts with a single click 7. Can search through all our emails by using search options 8. There is an inbuilt Calendar for our quick meetings lookup in it Cons Hmm.. At Present, there's no cons or least liked about this software as I have been using it from past 2 years and going with the same speed till now :) Review Source Estefanie Arlet M. Analista de Personal Used the software for: 2+ years ### "Zimbra Collaboration Suite is a very useful communication tool that groups several functions." May 25, 2018 5.0 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. Pros 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. Cons 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. Review Source TK Tim K. PM Information Technology and Services Used the software for: 2+ years ### "A communication platform that worked when options were limited" April 27, 2022 3.0 I must stay, long before the current top 3 collaboration providers were reachable to most enterprises, zimbra was the best option and worked acceptably, but for the price now it is simply outdated. Though for companies looking for unattached and independent email and collaboration, it is the best option. All the other providers tie you into their ecosystems and bundle features that you might simply never use. Pros For an admin, it really gives much fine grained controls in configuration and setup and before cloud emails were affordable, it was unbeatable in its offerrings of collaboration features. Its contact management is also great. Cons The interface is unfriendly, to setup and manage is also quite a task and support is not all that. The features are also quite outdated. Switched from [cPanel & WHM](https://www.capterra.com/p/165247/WHM/) Cpanel email or webmail as its better known is too unrealible in guaranteeing deliverability of emails. Review Source Deepak M.

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

May 30, 2018 5.0 Zimbra Collaboration Suite has brought me many benefits professionally speaking. Having this software has been a very pleasant experience since we migrated from another mail service to Zimbra. With this things seem simpler. Its interface helps a lot so that any user finds it easy to handle it. Pros What I like most about the Zimbra Collaboration Suite is that it groups several services in a single package. To have a list of contacts, a tool to plan activities, a calendar and most importantly: email service, covers all my needs at a professional level. It has been the best investment that has been made in the institution where I have been working for several years. Cons I really do not find major flaws in this software. For a low price I think it covers very well the needs that can be presented to us in an office to keep communications. Review Source Michelangelo C.

I come from Plesk's mailbox management and the difference is really abysmal . Pros A really fluid, convenient, fast and efficient management of email accounts. They have a plan for small businesses, the kickstart, which is perfect for those who have few boxes under management. The assistance is kind, punctual and courteous and their salesmen are very good.

SOFTWARE TRAINEE Information Technology and Services Used the software for: 6-12 months ### "About Zimbra" March 26, 2019 4.0 Firstly we use this software to check the incoming mails from clients or colleagues. The experience is quite good while using this software as it is fast, more secure. It blocks the mails from the third party systems which are not trusted by this zimbra collaboration suite. We can integration this suite with informative applications like Ted, IBM redbooks to view our daily feeds which is quite helpful for the people who are more interested in gaining knowledge. Instead of sending individual messages to the clients or colleagues we send frequently, there is a looping option where we can send so many mails by copying the same people we send the mail often. We can flag the mails in case of important mails and store it in a directory for any necessary information that is contained in the mail. We can use emojis and stickers for friendly interactions with the people within the organization. We have quite a few regular options like Changing the font, font size, sending attachements along with the emails, referring of the previous mails. We can save the incoming mails by enabling the offline mode in case we are using zimbra in our personal computer. There is an inbuilt archive option where we can archive folders of big size for size compression so that it can be easily transmitted through a dedicated network. We can save all our business contacts. My overall experience using this software is so satisfying. Pros 1) Can be accessed through any browser like Chrome, Firefox, Edge etc.. 2) Can be accessed through Personal Computer and Mobile 3) Inbox folders, addresses, contacts, tasks, calender scheduling dates can be shared among multiple users 4) Can schedule group meetings with a specific date and time using calenders 5) Personal tasks can be assigned or tasks can be assigned in groups. The progress of the task can be specified and the works to do further in regards to the task can also be specified. 6) A specified directory called brief case is available to store our files. 7) Zimlets are available to make the conversations between end to end users in a more formal, more interactive way. 8) Tags can be used to filter out the incoming mails that is to be called out in a particular category. Cons I didn't find any Cons. I find the working of this software Swift and smooth with no time lags while loading the incoming mails. Review Source cW cindy W.

It helps to be able to have different days laid out on the sheet for one person and that I can go back and forth. The layout makes sense for keeping people organized and aware of what is happening next on their calendar. I also like that I can easily flow between one person's agenda and the next rather than having everyone's schedule on one calendar and having color coordination. I think Zimbra is much simpler in that way. Cons I can't say that there's anything I dislike about it so far. It has been easy to use for our purposes. Review Source CW Calvin W. Director Computer Software Used the software for: 2+ years ### "Not bad, but not perfect either."

Pros I liked the fact that one can run it on a browser, making it compatible with any operating system. Email categorization with folders makes it easier to organize correspondence than Google mail.
