Our customers are able to use this groupware solution to connect to Active Directory and OpenLDAP, although Postgres support would be an improvement.
Zarafa has several very valuable features, among them a very good Outlook-like web interface. Furthermore, ZPush for talking between ActiveSync and mobile devices is a valuable asset. In addition, one is able to connect via Outlook and the exchange protocol to Zarafa. This makes Zarafa a free, and working, alternative to Microsoft Exchange.

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

"This makes Zarafa a free, and working, alternative to Microsoft Exchange."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"We can control all the data in my IT infrastructure."
"Good email solution and it's open-source."
"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."
"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
 

Cons

"Not really, although the Zarafa-index component was using a lot of memory and disk I/O bandwith."
"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."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"There are some security issues."
"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."
"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 Collaboration's video conferencing could be improved."
"The tool should improve its multi-cloud feature."
"It does have a few bugs."
 

Pricing and Cost Advice

Information not available
"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."
"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."
"The solution is not expensive compared to other products."
"We do not pay for licenses to use this solution."
"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."
"The solution is competitively priced."
"We pay yearly licenses for Zimbra Collaboration."
