Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

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

"Its price is the most valuable. It is definitely one of the lowest price solutions."
"IceWarp has multiple applications that are easy to use for many people."
"It has great communication capabilities for team chatting and web conferences."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"The TeamChat feature has been really good for our email management. It lets us collaborate, share files, and invite guests like Google Spaces or Microsoft Teams. I like the two-factor authentication for security. However, they need to improve their document collaboration tools, as their Word, Excel, and PowerPoint features are basic compared to Microsoft and Google."
"It's scalable and stable."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"The most valuable feature is sending messages as well as text and documents. It's a big solution for us since internal communication is a must in our organization."
"Network NG Modules are valuable to us."
"The backup and storage management features of Zimbra Collaboration are valuable."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"Zimbra Collaboration has a good web interface."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The configuration is simple."
 

Cons

"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"The solution should improve the mailing list feature. Google has a similar feature where you can automate sending files to different people in a sequence, but that feature is no longer available in the current version of IceWarp. Other features may also have been removed in the current version."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"The solution needs improvements in security, particularly regarding document management."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"The tool's configuration capabilities are not straightforward. Apart from that, if I want to archive emails into a vault so that they can be retrieved again later, the integration doesn't work, and IceWarp crashes."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"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."
"The tool should improve its multi-cloud feature."
"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."
"It is good and competent, but you have to pay for video and group chat features."
"The antispam and antivirus features are hard to understand on mobile devices."
"File sharing permissions with Nextcloud integration need improvement."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The solution’s forums don't have much information or documentation on administration tasks."
 

Pricing and Cost Advice

"The solution is inexpensive which is its main benefit."
"It is definitely one of the lowest price solutions."
"I don't see any challenges for the Indian market. For example, 1 GB is available for around 399 INR, and 2 GB for 499 INR. They offer a range of plans, from basic to professional and enterprise, with multiple features. IceWarp's aggressive pricing is competitive compared to other market solutions like Zoho and Microsoft. One significant advantage is that IceWarp does not impose user capping like Google and Microsoft, which allows for substantial cost savings and flexibility in user conversion."
"Costs far less than other solutions."
"There are various licensing plans available based on geographic zone."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"The license is based on the number of users."
"Pricing and licensing is very competitive and in some cases, cheap."
"We pay yearly licenses for Zimbra Collaboration."
"The price of the solution is low."
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"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."
"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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
