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

"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."
"The solution is inexpensive which is its main benefit."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"An effective, functional, very good tool for controlling resources at a low cost."
"It's scalable and stable."
"The groupware module is the most valuable feature."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"IceWarp offers very extended cross-platform communication solutions."
"We implement this solution in our data centers, and we have high availability."
"It's a fast solution."
 

Cons

"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
"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. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"The database query for creating new database and querying about activities are too simplistic."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"The Exchange compatibility mode is rather limited."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"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

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