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

"The cost-effectiveness of the solution is most valuable."

"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."

"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."

"Zimbra Collaboration has a good web interface."

"Zimbra Collaboration's sharing features are most valuable."

"The most valuable feature of Zimbra Collaboration is the cost."

"The solution is easy to implement."

"We can control all the data in my IT infrastructure."

"Good email solution and it's open-source."

"The most valuable feature of Zimbra Collaboration is email functionality."

More Zimbra Collaboration pros

Cons

"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."

"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 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."

"It does have a few bugs."

"There are some security issues."

"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."

"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."

"The tool should improve its multi-cloud feature."

"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."

"We pay yearly licenses for Zimbra Collaboration."

"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."

"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."

"The solution is competitively priced."

"Zimbra Collaboration offers a good price-to-feature ratio."

"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."

"We do not pay for licenses to use this solution."

"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
