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.

Deploys quickly and has a good web interface
Zimbra Collaboration has a good web interface When it comes to administration tasks like configuring specific filters or group signatures, I have to dig into the configuration since there's nothing in the graphical or web interface. The solution’s forums don't have much information or…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Very secure with great storage capacity."
"The cost-effectiveness of the solution is most valuable."
"The most valuable feature of Zimbra Collaboration is email functionality."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The most valuable feature of Zimbra Collaboration is the cost."
"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 product is easy to set up."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"Good email solution and it's open-source."
 

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 should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"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."
"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 new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"It does have a few bugs."
"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 installation is not straightforward, it can take two days for the full implementation."
"The solution’s forums don't have much information or documentation on administration tasks."
 

Pricing and Cost Advice

"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."
"It was a part of the suite, so it was very cost-effective. There were no costs beyond the licensing fee."
"The solution is not expensive compared to other products."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We pay yearly licenses for Zimbra Collaboration."
"The price of the solution is low."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"We do not pay for licenses to use this solution."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
