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

"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."

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

"I would advise others who are looking into implementing this product to go for it."

"The solution is very flexible and has great storage capacity."

"Very secure with great storage capacity."

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

"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."

"Zimbra Collaboration has a good web interface."

"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."

"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."

"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."

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

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

More Zimbra Collaboration pros

Cons

"Customer support did what they could but we had some issues because it required coordination between GroupWise and SUSE Linux or the Micro Focus storage support. It became a ping pong between these two parts of the same company and was unpleasant."

"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."

"I would like to see a Microsoft schedule function added."

"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."

"There are security and performance issues which is one of the concerns of using an open-source product."

"It does have a few bugs. However, they are small and can be worked around."

"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 is not very stable, but it's okay."

"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."

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."

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

"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."

"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."

"The solution is not expensive compared to other products."
