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.

Integrated email security has improved phishing response and provides better threat visibility
Microsoft Exchange Online could be improved with more intuitive administration workflows, better troubleshooting visibility, and simpler mail flow analysis for complex environments. We would also appreciate more granular reporting, faster access to detailed message tracking data, and improved alerting around suspicious mailbox activity to help security and messaging teams investigate issues more efficiently. One area where Microsoft Exchange Online could improve is the administrative user experience. Some advanced mail flow, compliance, and troubleshooting tasks still require navigating multiple Microsoft portals. A more unified management interface and deeper integration visibility across Exchange, Defender, and Microsoft 365 security tools would make day-to-day operations more efficient for administrators and SOC teams.

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."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"IceWarp has multiple applications that are easy to use for many people."
"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's voice services work well for our company."
"It has great communication capabilities for team chatting and web conferences."
"The solution is inexpensive which is its main benefit."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing."
"Microsoft Exchange Online is one of the best email solutions in the world."
"The solution is scalable."
"Exchange Online is a straightforward cloud-based application. It's easy to connect and the interface is user friendly."
"It is a scalable product. We are using it for 500 users."
"It is a very stable system, and it does what we ask it to do."
"The initial setup is straightforward and easy to configure."
"The most valuable feature is being able to assign an individual a task."
 

Cons

"Customer service is not always helpful."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"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."
"The stability of the solution on Mac products has room for improvement."
"The pricing could be cheaper."
"The interface is a bit confusing."
"The mail-blocking feature is not great and could be improved."
"I think there should be an incorporation of DLP on the business premium version of Exchange, as well."
"The cost is very high, and not every customer can afford licenses."
"Exchange Online has issues with its mail flow and content search."
"I don't like it in general. It sort of has that Microsoft flavor to it, which is just the style they use and the way they color things and lay them out."
 

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."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Our licensing is on a yearly basis. There were no additional costs."
"Pricing and licensing is very competitive and in some cases, cheap."
"The solution is inexpensive which is its main benefit."
"The solution is priced well."
"Costs far less than other solutions."
"I have no opinion."
"I would give the cost a five out of ten."
"This is an expensive solution."
"The price of Microsoft Exchange Online security could improve. The overall price of the solution is reasonable."
"I find it reasonably priced."
"I would say the solution is reasonable and affordable."
"The license for the solution is cheap, but it could be more affordable in the long term."
"We have an enterprise agreement for licensing."
