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.

Quick solution, but not very user-friendly or suitable for collaboration
It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365. An additional feature I would like to see is the ability to connect from different devices. Zimbra could be more user-friendly and deploy security rules. The integration with Outlook could be better to share agendas.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"If you have a small to medium business and you require a professional collaboration server that focuses on the main services of emails and calendar scheduling, I recommend IceWarp."
"The solution is inexpensive which is its main benefit."
"An effective, functional, very good tool for controlling resources at a low cost."
"It's scalable and stable."
"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."
"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."
"IceWarp has multiple applications that are easy to use for many people."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"It's a fast solution."
"We implement this solution in our data centers, and we have high availability."
 

Cons

"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."
"The solution needs improvements in security, particularly regarding document management."
"The Exchange compatibility mode is rather limited."
"Customer service is not always helpful."
"The database query for creating new database and querying about activities are too simplistic."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"Support is not good and it is challenging to receive a timely response."
"It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365."
