Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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.

Quotes from Members

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

Pros

"Go for it! I think it's an excellent product with great technical support."
"A stable solution."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"Ability to create your own content-filtering policies with relative ease."
"As the license of our company is very affordable per year and per user, and considering the almost-zero administration needs, I would say that the cost is returned in the first three months, compared to other solutions."
"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."
"IceWarp has multiple applications that are easy to use for many people."
"An effective, functional, very good tool for controlling resources at a low cost."
"The solution is inexpensive which is its main benefit."
"The solution's voice services work well for our company."
"The groupware module is the most valuable feature."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
 

Cons

"Malware needs improvement."
"I am not satisfied with Clearswift because of the lack of customer support."
"FTP server and TRUST Manager functionality."
"The solution needs improvements in security, particularly regarding document management."
"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."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"Our customers sometimes have problems receiving mail."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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."
"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
