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.

More Zimbra Collaboration pros

Cons

More Zimbra Collaboration cons

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."

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

"The price of the solution is low."

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

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

"We pay yearly licenses for Zimbra Collaboration."

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

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

"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."
