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.

Our customers are able to use this groupware solution to connect to Active Directory and OpenLDAP, although Postgres support would be an improvement.
Zarafa has several very valuable features, among them a very good Outlook-like web interface. Furthermore, ZPush for talking between ActiveSync and mobile devices is a valuable asset. In addition, one is able to connect via Outlook and the exchange protocol to Zarafa. This makes Zarafa a free, and working, alternative to Microsoft Exchange.

Quotes from Members

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

Pros

"IceWarp offers very extended cross-platform communication solutions."
"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."
"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 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 solution is easy to manage and includes features such as smart documents and the archiving of user data."
"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."
"It has great communication capabilities for team chatting and web conferences."
"The solution is inexpensive which is its main benefit."
"This makes Zarafa a free, and working, alternative to Microsoft Exchange."
 

Cons

"The Exchange compatibility mode is rather limited."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"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."
"The solution needs improvements in security, particularly regarding document management."
"Our customers sometimes have problems receiving mail."
"Not really, although the Zarafa-index component was using a lot of memory and disk I/O bandwith."
 

Pricing and Cost Advice

"The license is based on the number of users."
"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."
"There are various licensing plans available based on geographic zone."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"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."
"It is definitely one of the lowest price solutions."
