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

"The integration of Microsoft Exchange with other tools allows for seamless collaboration and increased productivity within teams."
"The initial setup is quite a straightforward process. I don't think it is a very complicated solution. Plenty of things could be more complex, but the ordinary, general settings are quite simple."
"Microsoft Exchange is highly stable for the end-user systems. When we move to Office 365, it will be even more stable even. There's less administration required and it's very robust. We are really quite happy in using that."
"On-premises Microsoft Exchange is good because it protects data privacy."
"We've been using Exchange as an email platform. Our clients require multi-country, multi-regional email collaboration with controlled mail flow. The most valuable feature is the capability of message tracking and the protection of user data."
"It ensures high availability and resilience, allowing seamless recovery from potential failures and making it a reliable option for business-critical operations."
"It is easy to use and we can allow many users because now our users are scattered They over a wide area. We can use it from anywhere. That is the main benefit for us."
"The email management system is very easy to set up, configure, and use."
"The configuration is simple."
"Network NG Modules are valuable to us."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The stability is good and keeps getting better with each new update."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"The most valuable feature of Zimbra Collaboration is the cost."
"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

"I would like to see Microsoft Exchange improve their documentation."
"The setup is difficult so could be easier."
"In terms of what should be improved, they should probably move to a cloud option like Office 365. We would like to get this functionality without the need to deploy complex hardware and software solutions. This should be the next thing, making Exchange more related to Office products, which are more cloud-oriented, less on-premise or desktop-oriented solutions, like the direction Google is strongly moving towards."
"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."
"Microsoft needs to make some modifications to meet the current needs of the environment. For example, they need to add more cell service features because people work from home during the pandemic, and certain elements should be available as a mobile service."
"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."
"The support needs to be more knowledgeable."
"The security features could be improved. There should be a better policy management system."
"It would be great if a group chat feature were created to allow for a team environment."
"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."
"The tool should improve its multi-cloud feature."
"Zimbra Collaboration's video conferencing could be improved."
"The product must be more customizable."
"There are some security issues."
"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."
"It does have a few bugs."
