Great security, stability, versatility, expandability and low cost of ownership.

I like the ease of login best in GroupWise. With the desktop client you can login to GroupWise independently of the PC login and it has Web Client that can be used if your prefer not to install the client or are using a PC that does not have the GroupWise Client installed. I also like its user proxy capabilities. I also like the level of security that it provides. Additionally, it comes with GroupWise Messenger for secure instant messaging to desktop or mobile devices. It integrates well with the email on your mobile devices and smart phones via GroupWise Mobile Services.

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."

"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."

"The stability is good and keeps getting better with each new update."

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

"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."

"The backup and storage management features of Zimbra Collaboration are valuable."

"The Zimbra Collaboration's most valuable feature is web access."

"Zimbra Collaboration has a good web interface."

"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."

More Zimbra Collaboration pros

Cons

"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."

"Their support can be improved. It is not as good as it used to be."

"We have had an issue with security."

"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."

"There are some bugs we found that could be fixed."

"There are some security issues."

"There can be difficulties resolving problems on the server side when problems arise."

"Zimbra Collaboration's video conferencing could be improved."

"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."

"Server deployment and the GUI for emails should be better."

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."

"Zimbra Collaboration is expensive, and there is no perpetual license option."

"The price of the solution is low."

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"

"The solution is competitively priced."

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

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

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