"The solution offers great features."
"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 the cost."
"The product is easy to set up."
"The most valuable feature is sending messages as well as text and documents. It's a big solution for us since internal communication is a must in our organization."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"Good email solution and it's open-source."
"The Zimbra Collaboration's most valuable feature is web access."
"The web interface is powerful and easy to use."
"NVMe support is lacking when it comes to performance on the disk side."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"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."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"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."
"It does have a few bugs."
"Zimbra Collaboration's video conferencing could be improved."
