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.
Muhammad Talha Baig - PeerSpot reviewer
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."
"The cost-effectiveness of the solution is most valuable."
"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."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"Zimbra Collaboration's sharing features are most valuable."
"The stability is good and keeps getting better with each new update."
"The backup and storage management features of Zimbra Collaboration are valuable."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"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."
 

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."
"Their support can be improved. It is not as good as it used to be."
"The WebAccess feature is somewhat lacking and could be improved."
"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 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."
"The solution could improve by making it easier to use."
"The tool should improve its multi-cloud feature."
"It does have a few bugs."
"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 product must be more customizable."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
 

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."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. 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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
"Zimbra Collaboration offers a good price-to-feature ratio."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"The solution is not expensive compared to other products."
