Hesham Hussain - PeerSpot reviewer
A good solution for large enterprises, but is expensive when compared to other solutions
Regarding the decision of increasing the number of users, it depends on the organization's choice, whether to opt for CapEx or OpEx. Both options involve expenses over the years. Building an in-house Exchange solution requires investing in hardware, storage, connectivity, and administrative resources. Office 365 shifts the budget solely to OpEx as a subscription service. Scalability is another factor. Starting a new company favors Office 365 due to cost efficiency. As the organization grows, the choice depends on available resources and technical expertise. An internal Exchange setup is feasible with skilled engineers, while Office 365 suits those lacking in-house resources.

One of the premium features was customized rooms tailored to the collaboration needs
Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is very well integrated with other Microsoft programs, teams, and so on. They work well together."
"The exchange functionalities are good."
"It's user-friendly."
"On-premises Microsoft Exchange is good because it protects data privacy."
"Technical support is good."
"Provides unlimited storage for our mailbox."
"Now, we manage to serve almost 99% of the information."
"The most valuable features are that you can exchange information, tasks, attachments, and enhance the process in a short amount of time."
"The most valuable feature is sending messages as well as text and documents. It's a big solution for us since internal communication is a must in our organization."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"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."
"Good email solution and it's open-source."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
"The stability is good and keeps getting better with each new update."
"The Zimbra Collaboration's most valuable feature is web access."
 

Cons

"The management of .pst files and archiving need improvement."
"For new users, it might take them some time to get used to the product."
"The pricing could be better, and it could have an easier implementation."
"Load balancing is lacking."
"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."
"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."
"Microsoft Exchange needs to improve how it handles and assigns policy and security."
"We are not able to use Microsoft Teams due to connection issues. Thus, the product integration with Teams could be improved."
"Zimbra Collaboration's video conferencing could be improved."
"The antispam and antivirus features are hard to understand on mobile devices."
"File sharing permissions with Nextcloud integration need improvement."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"It would be great if a group chat feature were created to allow for a team environment."
"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."
"There are some security issues."
"They should enhance its online meeting features."
 

Pricing and Cost Advice

"Its price is okay."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"It is not expensive."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"The product pricing is reasonable if you utilize its full suite of features."
"Its price is fair."
"The product is quite cheap."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Zimbra Collaboration offers a good price-to-feature ratio."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The solution is not expensive compared to other products."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"We pay yearly licenses for Zimbra Collaboration."
