"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."

"Zimbra Collaboration's sharing features are most valuable."
"NVMe support is lacking when it comes to performance on the disk side."
"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."
"It would be great if a group chat feature were created to allow for a team environment."
"It is good and competent, but you have to pay for video and group chat features."
"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 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 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."
"The antispam and antivirus features are hard to understand on mobile devices."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
