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

"Its price is the most valuable. It is definitely one of the lowest price solutions."
"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 groupware module is the most valuable feature."
"The solution's voice services work well for our company."
"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."
"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."
"This makes Zarafa a free, and working, alternative to Microsoft Exchange."
 

Cons

"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."
"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."
"Customer service is not always helpful."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"Our customers sometimes have problems receiving mail."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"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."
"The solution is priced well."
"Our licensing is on a yearly basis. There were no additional costs."
"There are various licensing plans available based on geographic zone."
"It is definitely one of the lowest price solutions."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"The solution is inexpensive which is its main benefit."
