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 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."
"The most valuable features are that you can exchange information, tasks, attachments, and enhance the process in a short amount of time."
"The search tools are good."
"It is easy to set up."
"The deployment is a plug-and-play process."
"It's user-friendly."
"Exchange has helped us with encryption."
"The latest versions have gotten much better about balancing the load on the backend."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"The web interface is powerful and easy to use."
"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 most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"The product is easy to set up."
"The stability is good and keeps getting better with each new update."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"The most valuable feature of Zimbra Collaboration is email functionality."
 

Cons

"Some users encounter stability issues. I connect with the support team through my local partner, which takes time."
"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."
"In our current situation, the disappearance of sanctions would be a tangible improvement. We are basically cut off from technical support and it's very difficult to obtain any updates."
"The main problem with Microsoft products is that we're constantly required to install patches and fixes."
"There can be occasional challenges during the product's implementation phase, making it an area where improvements are needed."
"For the next release, there are some features on the cloud-based Exchange that aren't included on-prem. It would be great if these features were made available in the next release. For instance, integration between Exchange and its on-prem calendar is not available for the on-prem solution."
"The product or service could be improved in terms of Microsoft Outlook client compatibility."
"For new users, it might take them some time to get used to the product."
"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."
"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."
"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."
"They should enhance its online meeting features."
"File sharing permissions with Nextcloud integration need improvement."
"The antispam and antivirus features are hard to understand on mobile devices."
"It does have a few bugs."

When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost.

Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."
