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

"I would highly recommend this solution to others and this is because of its stability, scalability, and reasonable pricing."
"For me, the solution is very user-friendly. I've used it a long time and I know where everything is."
"The tool's most valuable feature is associated with the fact that it stands out for being beneficial for managing emails."
"We've been using Exchange as an email platform; our clients require multi-country, multi-regional email collaboration with controlled mail flow, and the most valuable feature is the capability of message tracking and the protection of user data."
"Communication is the most valuable feature of the solution."
"Exchange has all the calibration features you need."
"With the cloud coming in, scalability is not an issue even for Microsoft."
"The most used feature of Microsoft Exchange is the email capability, especially since it integrates with the calendar."
"Network NG Modules are valuable to us."
"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, and the solution really does scale very easily."
"The stability is good and keeps getting better with each new update."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"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."
"Despite sticking with Gmail for over a decade in terms of business, Zimbra have impressed me with some other aspects as well; if the time comes, I would prefer Zimbra to my current solution."
"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 Collaboration has integrated a lot of their party tools and they have good documentation available."
 

Cons

"Microsoft Exchange could improve security. They can elevate a lot of security features."
"The desktop version of Microsoft Exchange receives emails a little slower than the online version."
"It is overall all good, though technical support is just average."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"They could improve on the search function, it takes too much time."
"The antispam and antivirus features are hard to understand on mobile devices."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
"Zimbra is not very stable, but it's okay."
"I would like to see a Microsoft schedule function added."
"There are security and performance issues which is one of the concerns of using an open-source product."
"The installation is not straightforward, it can take two days for the full implementation."
"The log files need to be improved; they need to show us more information because a lot of detail is lacking and that's not very helpful or insightful."

Pricing and Cost Advice
