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

"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 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."
"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."
"The solution's voice services work well for our company."
"It has great communication capabilities for team chatting and web conferences."
"The solution has a very good log-in to the UI when compared to other solutions."
"It's a fast solution."
 

Cons

"The exchange compatibility mode is rather limited. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"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."
"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."
"Our customers sometimes have problems receiving mail."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"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."
 

Pricing and Cost Advice

"Costs far less than other solutions."
"Our licensing is on a yearly basis. There were no additional costs."
"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."
"I would rate the pricing and eight out of ten."
"It is definitely one of the lowest price solutions."
"The solution is priced well."
"The solution is inexpensive which is its main benefit."
"It's an open-source solution so it's free."
