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.

Reliable email service has supported consistent communication and improved user training
I do use Cisco Secure Email, Grafis, and Proofpoint Email Protection when needed, but we were using Proofpoint before, and we are no longer using it. I am currently using Microsoft Exchange as our email solution. We are a client of Microsoft; there is no partnership between my company and Microsoft. My experience with Microsoft Exchange is as good as the generic email. I do not use Microsoft Exchange to synchronize emails across devices, and it is not part of my workflow. The protocols I mostly use with Microsoft Exchange for integration are SMTP. I do not use the shared calendars feature in Microsoft Exchange. Data loss prevention is something we are not really using or utilizing at the moment. My overall review rating for Microsoft Exchange is 8.

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 solution has a very good log-in to the UI when compared to other 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 solution is easy to manage and includes features such as smart documents and the archiving of user data."
"It's scalable and stable."
"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."
"An effective, functional, very good tool for controlling resources at a low cost."
"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."
"We have found the solution to be stable; there are no bugs or glitches, the performance is good, and we don't worry about it crashing or freezing."
"It's pretty easy to manage."
"On-premises Microsoft Exchange is good because it protects data privacy."
"Exchange has helped us with encryption."
"It is user friendly."
"Support is very good."
"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"The setup was straightforward."
 

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."
"The solution needs improvements in security, particularly regarding document management."
"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."
"Support is not good and it is challenging to receive a timely response."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"Customer service is not always helpful."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"More AI features would be good."
"The product or service could be improved in terms of Microsoft Outlook client compatibility."
"Scalability probably is not proper."
"An area for improvement would be the convenience of working with Azure services from Exchange on-premise installations."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"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."
"I'd like the archiving process to be faster."
"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."
 

Pricing and Cost Advice

"Our licensing is on a yearly basis. There were no additional costs."
"There are various licensing plans available based on geographic zone."
"Costs far less than other solutions."
"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 is definitely one of the lowest price solutions."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Pricing and licensing is very competitive and in some cases, cheap."
"The solution is priced well."
"Microsoft Exchange itself does not require a license, but users who will have mailboxes will require a license. It depends on the number of users to choose which license. If you exceed 2,000 mailboxes, it's preferable to get the enterprise license."
"Microsoft Exchange is an inexpensive application."
"It's a little bit expensive."
"We are currently using enterprise licenses for the solution. They are different pricing models available. There are individual, cloud-based, and enterprise licenses all with different pricing models. The larger the number of users, the lesser the price. For small to medium companies like us, we feel it is expensive."
"This solution is expensive."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"It would be nice if it used less resources to run on-premise."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
