Great security, stability, versatility expandability and low cost of ownership
About the only thing I don't like about GroupWise is the lack of a modern Linux client. Micro Focus stop their development of the Linux Client a long time because there wasn't enough demand for it. Most other solutions do not have the Linux client. I would really like to see OpenText add a modern GroupWise Linux Client back. But until they do there is the Web Client to be used in a browser.

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

"Very secure with great storage capacity."
"I like the ease of logging best in Micro Focus GroupWise. I also like its proxy capabilities from a user level. I also like how secure Micro Focus GroupWise is."
"The cost-effectiveness of the solution is most valuable."
"The web interface is powerful and easy to use."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
"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 Zimbra Collaboration's most valuable feature is web access."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"The solution is easy to implement."
 

Cons

"What I don't like about Micro Focus GroupWise is the removal of the Unix client. Micro Focus took that function away about ten years ago because there wasn't enough demand for it."
"The WebAccess feature is somewhat lacking and could be improved."
"Their support can be improved. It is not as good as it used to be."
"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."
"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."
"They should enhance its online meeting features."
"Zimbra Collaboration's video conferencing could be improved."
"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."
"I would like to see a Microsoft schedule function added."
"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."
 

Pricing and Cost Advice

"It was a part of the suite, so it was very cost-effective. There were no costs beyond the licensing fee."
"Micro Focus GroupWise is the most affordable solution on-premises. Versus Microsoft Exchange on-premises, pricing is 20:1, so there's no comparison. Micro Focus GroupWise is cheaper, though, for my clients, it's not about the cost but the stability and security of the solution."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We pay yearly licenses for Zimbra Collaboration."
"When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The price of the solution is low."
"We do not pay for licenses to use this solution."
