Automatic backup with good web client features for an easily scalable, stable, installable and manageable solution
Pros and Cons
  • "One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
  • "It would be great if a group chat feature were created to allow for a team environment."

What is our primary use case?

While I believe that Zimbra nine is the latest update, I am working with eight. 

The solution employs open source software. 

I implement the solution so that our end user customers may have mailing features, one-on-one chat facilities and unified communication. Within one's email are contained his calendaring facilities. 

What is most valuable?

One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software. The web client features have good graphics and are pretty useful. 

What needs improvement?

It would be great if a group chat feature were created to allow for a team environment. The current chatting facility only allows for one-to-one chats. 

For how long have I used the solution?

I have been using Zimbra Collaboration for nearly two years.

What do I think about the stability of the solution?

The product is very stable. One need only implement it, at which point it does not require further contemplation. Only basic maintenance is required. 

What do I think about the scalability of the solution?

The solution is easy to scale. It boasts scalability features such as those allowing an additional server to be added for horizontal scaling.We have encountered no issues in this regard. 

How are customer service and support?

We have not required much technical support, as the implementation we do primarily concerns the community edition with which we started. We feel the technical support to be good. They supply good email support. We do not require this at the moment. 

Which solution did I use previously and why did I switch?

Nearly two years back, I was working with Microsoft Exchange. 

The advantage of Microsoft Exchange over Zimbra Collaboration is that it is very heavy and has much more features, but its management requires a person to have a greater level of skill. Microsoft is also a more mature solution. 

When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange. Microsoft has multiple requirements, such as one concerning the need for the best OS licenses. There are multiple products needed to get Microsoft Exchange to work, but there is also a standalone option available. The licensing of Zimbra Collaboration is better than that of Microsoft Exchange and it's more affordable. 

How was the initial setup?

The initial setup is simple. As the implementation is pretty simple, a small organization can initially make use of the community edition and move on from there. 

What about the implementation team?

The management of the solution is simple. Save for mailbox related issues, the maintenance of the solution is minimal. Issues are limited to comparatively minor ones and mainly would arise at the SMTP end. 

What's my experience with pricing, setup cost, and licensing?

The licensing of Zimbra Collaboration is better than that of Microsoft Exchange and it's more affordable. 

What other advice do I have?

The product is on the client side, so our company provides implementation and support services. 

The solution is best suited for medium enterprises, although my organization supports mainly government organizations which range from medium to large. 

I rate Zimbra Collaboration as an eight out of ten.

Has all collaboration features and very good stability and scalability
Pros and Cons
  • "It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
  • "Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."

What is our primary use case?

We are using it as an email server and collaboration suite.

What is most valuable?

It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing.

It is awesome in terms of stability and scalability.

What needs improvement?

Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client.

For how long have I used the solution?

I have been using this solution for approximately nine years.

What do I think about the stability of the solution?

Its stability is very good.

What do I think about the scalability of the solution?

Its scalability is very good. We have approximately 900 users. We have one person for its maintenance.

How are customer service and support?

Their technical support is good.

Which solution did I use previously and why did I switch?

We migrated from IBM Lotus Domino.

What's my experience with pricing, setup cost, and licensing?

We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis.

What other advice do I have?

I would rate Zimbra Collaboration an eight out of 10.

Fast, reliable, and scalable
Pros and Cons
  • "A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
  • "I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."

What is most valuable?

Zimbra is open source. They got absorbed by Yahoo, but they're still primarily open-source and have continued to extend their technology. A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra. And with Exchange, it's not easy to purchase the license. And Zimbra is more reliable in terms of integration.

What needs improvement?

Yahoo acquired Zimbra, and Yahoo Mail is a web-based email, not a software platform. So as part of the acquisition, they have to continue providing support to the open-source license holders. But lately, they have decreased their support for the open-source community, and they're pivoting to the enterprise market. So they're starting to transition to a proprietary cloud-based solution. And when they adopt this proprietary solution, it won't be good. So hopefully, in the future, they'll continue to offer an open-source version. That's what makes Zimbra trustworthy for users as an email host. Email is still essential for communities and businesses. Even if you are currently using instant messaging or any communications tool, you still need email. 

Maybe Zimbra can improve by implementing an architecture that mimics social media, like offering short messages instead of just email. Instant messaging can mean light messaging or group messaging, like a B2B chat or something like that.

For how long have I used the solution?

We've been using Zimbra for about four or five years.

What do I think about the scalability of the solution?

Zimbra is roughly as scalable as Microsoft, but I haven't deployed Zimbra for any huge clients yet. For example, all of my clients have fewer than 2,000 users. So if they had more than 2,000, I couldn't say whether Zimbra could manage that or not. But I know that Microsoft can work with clients that serve 10,000-plus users. 

So in my experience, I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many.

How was the initial setup?

It's easy for me because I have worked with Zimbra concepts since Yahoo acquired it in 2007, but I can't speak for the average users.

What other advice do I have?

I rate Zimbra Collaboration eight out of 10. It stacks up well compared to OWA or Microsoft Exchange. I've developed solutions for my clients using all of these. And compared to other web applications, I prefer the web-hosted Zimbra. I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version.

Great dashboard, a modern user interface, and excellent scalability
Pros and Cons
  • "The stability is good and keeps getting better with each new update."
  • "The solution could use more integration with third-party tools."

What is our primary use case?

We primarily install Zimbra Collaborations for the many customers that we have. It's primarily used for networking and collaboration.

What is most valuable?

The pricing of the solution is excellent.

It's a newer solution with a modern interface and dashboard.

The interface itself is very responsive and easy to navigate.

The initial setup is very simple and straightforward.

The stability is good and keeps getting better with each new update. 

The pricing of the product is excellent. 

The solution really does scale very easily. 

Technical support is quite helpful.

What needs improvement?

We are simply a customer and an end-user. We don't have a business relationship with the organization.

The log files need to be improved. It needs to show us more information. Right now, a lot of detail is lacking and that's not very helpful or insightful.

The solution could use more integration with third-party tools. That would be very useful.

For how long have I used the solution?

I've been working with the solution for two years at this point. It hasn't been too long.

What do I think about the stability of the solution?

The solution is quite stable. In fact, its stability continues to grow with updates. It doesn't crash and freeze. there are no bugs or glitches. It's reliable.

What do I think about the scalability of the solution?

Zimbra is very, very scalable. We can start small and go from 20 accounts to very high numbers of additional accounts. It's quite easy to do. If a company needs to scale, it can do so very quickly.

How are customer service and technical support?

I've been in contact with technical support in the past and I find that they are quite good. They are helpful and responsive. they are knowledgeable about the product and they are helpful when we have queries. We are satisfied with their level of attention.

How was the initial setup?

The initial setup is quite straightforward and very simple. It's not overly complex or difficult. It shouldn't prove to be too much of a challenge.

What about the implementation team?

We install the solution for our customers.

What's my experience with pricing, setup cost, and licensing?

The solution is very low cost. It's an open-source solution. It's not an expensive option.

What other advice do I have?

I'd recommend the solution to other organizations due to the fact that the solution very low-cost and it's an open-source option - which is very attractive to many companies. We installed it in a Linux system so that we can get more security on our platform. 

I'd rate the solution at an eight out of ten. We are quite satisfied with the capabilities of the product.

Web interface powerful, easy to use, and stable
Pros and Cons
  • "The web interface is powerful and easy to use."
  • "The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."

What is our primary use case?

We are using the solution for inhouse emails.

What is most valuable?

The web interface is powerful and easy to use.

For how long have I used the solution?

I have been using the solution for a couple of years.

What do I think about the stability of the solution?

The solution is very stable.

What do I think about the scalability of the solution?

From what I have heard the solution is scalable. I have not had an experience with scaling it but I am aware of some very large companies that use it.

How are customer service and technical support?

The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved. 

With the networking edition of the solution you receive 
the full support options.

What's my experience with pricing, setup cost, and licensing?

If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported.

What other advice do I have?

My advice is to try and make sure that the target environment is suited for the web interface because that is where most of its features are found.

I rate Zimbra Collaboration a nine out of ten.

It is light to manage and low-cost, but lacks storage management
Pros and Cons
  • "Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
  • "Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."

What is our primary use case?

We are mostly using Zimbra Collaboration for email purposes. It is also a collaborative tool. We also use it for sharing some documents and for meetings. 

What is most valuable?

Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management.

Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. 

The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution.

What needs improvement?

Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server.

They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult.

Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure.

For how long have I used the solution?

I have been using Zimbra Collaboration for almost six years.

How are customer service and technical support?

Zimbra doesn't have good technical support. They are not always available for help, so we have to troubleshoot as much possible by ourselves. It is not easy to find help when we have any incidents.

We have a local partner who is an expert in Zimbra. They really help us by trying their best and doing what they can do. Zimbra support is not always available, so we work only with local support.

How was the initial setup?

Because Zimbra doesn't provide good support, it was difficult for our administration team to handle this solution in the beginning. They had to learn it on their own. The initial setup, however, wasn't really difficult. It was simple.

What about the implementation team?

The teams in charge installed it in a short time with the help of a partner.

What's my experience with pricing, setup cost, and licensing?

Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. 

Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. 

The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate.

What other advice do I have?

I would recommend this solution, but it depends on the size of the company and the cost. The number of emails that you use impacts the cost of the solution. 

For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy. For a big company, Microsoft Exchange is good because you have to manage the data, storage, and user emails, and you need a tool that can easily do it for you. Microsoft Exchange provides tools to manage the space and the server. You can create your own policy for emails. For example, you can save emails that are two years old somewhere else. Zimbra Collaboration currently does not have such functionality, and it is something very inconvenient because the emails keep on increasing, and the storage is not unlimited. Therefore, you have to find a way to manage the storage to save all emails and have free space for the new ones. This functionality is really powerful in Microsoft Exchange. That's why for a big company with 1,000 or more users, it's good to have Microsoft Exchange. It, however, also depends on your budget.

I would rate Zimbra Collaboration a seven out of ten. In spite of the lower cost of Zimbra Collaboration as compared to Microsoft Exchange, our management is planning to migrate to Microsoft Exchange because of the issue with storage management.

We can control all the data in my IT infrastructure
Pros and Cons
  • "We can control all the data in my IT infrastructure."
  • "File sharing permissions with Nextcloud integration need improvement."

What is our primary use case?

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

How has it helped my organization?

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.

What is most valuable?

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

What needs improvement?

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

For how long have I used the solution?

More than five years.

I can manage all accounts from the console. Premium features don't break when you perform OS updates.

What is most valuable?

I like that I can easily manage all accounts from the management console. This allows real time control of each account. With the CLI, I can also control and manage all server functions or any mailbox, for free.

Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier. Once implemented, they don't break when you perform OS updates.

How has it helped my organization?

When my clients moved from POP3 to IMAP and ActiveSync, they were able to port the complete mailbox. Additionally, Zimbra allows them to centrally manage and store all their emails.

What needs improvement?

The following areas could be improved:

  • Backup
  • Autodiscover
  • Antispam
  • Mobile

I think being able to purchase individual packages would be better than having all the features included in one big package.

For how long have I used the solution?

I’ve been using Zimbra for more than 4 years.

What do I think about the stability of the solution?

We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming.

How are customer service and technical support?

The main format for technical support is forum-based with tickets. This is not appropriate for big enterprises.

Which solution did I use previously and why did I switch?

I have used Microsoft Exchange and PostFix. The main reason for switching to a Zimbra deployment is the cost in time.

How was the initial setup?

The first time I performed a setup it was harder than expected. I only had basic Linux skills and Zimbra installation wasn't as straightforward as it is now.

As I mentioned before regarding free products, we expect the end user to figure out how to make it work. When we pay, then we can complain.

What other advice do I have?

I recommend Zimbra for small and medium-sized businesses. Even larger enterprises could benefit from it. If they have a good system administrator and are willing to learn, they could reduce costs and improve performance, while increasing productivity as well.
