Efficient email management with seamless integration
We previously used Microsoft Exchange but have moved to an MDN email solution due to cost and user growth Microsoft Exchange is a user-friendly and easy-to-deploy solution, which is beneficial for handling emails even without professional support. It is effective in managing email integration…

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

"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"The most valuable feature of Microsoft Exchange is its ease of use."
"It ensures high availability and resilience, allowing seamless recovery from potential failures and making it a reliable option for business-critical operations."
"Microsoft Exchange saves time by allowing users to send emails or set schedules instead of making calls or holding meetings."
"It is very well integrated with other Microsoft programs, teams, and so on; they work well together."
"The latest versions have gotten much better about balancing the load on the backend."
"The most used feature of Microsoft Exchange is the email capability, especially since it integrates with the calendar."
"It's user-friendly."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The backup and storage management features of Zimbra Collaboration are valuable."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"The logs, troubleshooting, and tracking we have found to be the most valuable features, and when we have any issues with lost messages these features are useful because it is very easy to track and log."
"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."
 

Cons

"The security features could be improved. There should be a better policy management system."
"They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
"I see some drawbacks and areas for improvement; the quarantining is not fantastic because it lets a lot of spam through, and when it is notified of spam, it does not particularly alter its behavior quickly."
"They could offer simultaneous features for Exchange Online and on-premises versions. Specific features such as litigation hold and audit setups should be available on-premises."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."
"They could improve on the search function, it takes too much time."
"Deployment should become a bit easier, the process is a bit complicated. There are a lot of complications compared to Gmail For Business, which is a bit easier when it comes to configuration."
"Server deployment and the GUI for emails should be better."
"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."
"There can be difficulties resolving problems on the server side when problems arise."
"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."
"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."
"The solution could improve by making it easier to use."
"Zimbra Collaboration's video conferencing could be improved."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
 

Pricing and Cost Advice

"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"I have Outlook 365 Professional, and Exchange comes in the bundle with other solutions, such as Word and OneDrive. I pay for the use of the bundle monthly and I can imagine if you are a company with many licenses the pricing model would be a lot different."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"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."
"We are currently using enterprise licenses for the solution. They are different pricing models available. There are individual, cloud-based, and enterprise licenses all with different pricing models. The larger the number of users, the lesser the price. For small to medium companies like us, we feel it is expensive."
"Licensing fees are paid monthly."
"The platform has a reasonable price."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"We pay yearly licenses for Zimbra Collaboration."
"Zimbra Collaboration offers a good price-to-feature ratio."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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."
