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.

Has a straightforward setup process, but the functionality for replying to conversations needs enhancement
One major area for improvement is the need for repeated authentication when running a meeting. This requirement for users to sign in and authenticate their mail each time they access the service is complicated, as employees need to be able to access their accounts anytime, anywhere. Additionally, the functionality for replying to conversations using a link has deteriorated in the newer version of Outlook, an issue that needed to be present in previous iterations.

Quotes from Members

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

Pros

"The solution has a very good log-in to the UI when 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 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."
"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."
"IceWarp has multiple applications that are easy to use for many people."
"An effective, functional, very good tool for controlling resources."
"The solution's voice services work well for our company."
"It has great communication capabilities for team chatting and web conferences."
"Our customers are satisfied with the features included in Microsoft Exchange."
"I find the Outlook client very valuable. It allows me to connect to the Exchange Server and send and receive emails easily. The graphical interface is user-friendly and has a good look and feel."
"Microsoft Exchange is comparable to the Outlook client. Both are Microsoft products, and most people are familiar with Outlook. This is why the best feature of Microsoft Exchange is the ease of use. It is more compatible with the client software, especially for Microsoft Outlook. There are a lot of features available that are required for businesses users."
"It is a very stable tool...It is a very scalable tool."
"The technical support services are good."
"Microsoft Exchange is stable."
"The integration of Microsoft Exchange with other tools allows for seamless collaboration and increased productivity within teams."
"Microsoft has a very good support team."
 

Cons

"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."
"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 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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"Our customers sometimes have problems receiving mail."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"After 2022, users of Microsoft Exchange have to migrate mailboxes to Microsoft Exchange Online, and what I'd like to improve is for Microsoft to publish more on-premise versions for customers using Microsoft Exchange. Having more security is another room for improvement in the solution, particularly for mailboxes that develop the Exchange Edge rule to protect internal mailboxes. What I'd like to see from Microsoft Exchange in the future is for Microsoft to still update the latest, existing version which is 2022. I'd like Microsoft to still push more cumulative updates for Microsoft Exchange 2022."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"The management of .pst files and archiving need improvement."
"Microsoft Exchange's customer support could be faster and more knowledgeable."
"One major area for improvement is the need for repeated authentication when running a meeting."
"The solution's hybrid deployment process could be improved, particularly for customers who initially started in the cloud and may want to return to an on-premises setup. Microsoft could make this transition more flexible."
"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."
"They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
 

Pricing and Cost Advice

"Pricing and licensing is very competitive and in some cases, cheap."
"Our licensing is on a yearly basis. There were no additional costs."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"It is definitely one of the lowest price solutions."
"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."
"The solution's pricing is fine...I do think the tool offers value for money."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Licensing fees are paid monthly."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
"Its price is fair."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"It would be nice if it used less resources to run on-premise."
