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

Pros

"IceWarp offers very extended cross-platform communication solutions."
"IceWarp has multiple applications that are easy to use for many people."
"The solution has a very good log-in to the UI when compared to other solutions."
"It has great communication capabilities for team chatting and web conferences."
"An effective, functional, very good tool for controlling resources at a low cost."
"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's voice services work well for our company."
"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."
"It's a fast solution."
"We implement this solution in our data centers, and we have high availability."
 

Cons

"Customer service is not always helpful."
"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."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The Exchange compatibility mode is rather limited."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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."
"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."
 

Pricing and Cost Advice

"Costs far less than other solutions."
"There are various licensing plans available based on geographic zone."
"The solution is inexpensive which is its main benefit."
"The solution is priced well."
"I would rate the pricing and eight out of ten."
"Pricing and licensing is very competitive and in some cases, cheap."
"It is definitely one of the lowest price solutions."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"It's an open-source solution so it's free."
