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

"It's a very user-friendly application. The mail server is also valuable when compared to other services like SquirrelMail."
"The setup was straightforward."

"The product is easy to set up."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The solution is easy to implement."
"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."
"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."
"Good email solution and it's open-source."
"The backup and storage management features of Zimbra Collaboration are valuable."
"The configuration is simple."
 

Cons

"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."
"Microsoft Exchange could improve the archiving of emails and the performance."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."
"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."
"I'd like the archiving process to be faster."
"The solution's hybrid deployment process could be improved, particularly for customers who initially started in the cloud and may want to return to an on-premises setup. Microsoft could make this transition more flexible."
"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."
"They should enhance its online meeting features."
"There are some security issues."
"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."
"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."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"The solution could use more integration with third-party tools."
"The solution could improve by making it easier to use."
