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

"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 groupware module is the most valuable feature."
"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."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"IceWarp has multiple applications that are easy to use for many people."
"It's scalable and stable."
"The solution's voice services work well for our company."
"An effective, functional, very good tool for controlling resources at a low cost."
"Microsoft has a very good support team."
"It is easy to use and we can allow many users because now our users are scattered, they cover a wide area, and we can use it from anywhere, which is the main benefit for us."
"Exchange has helped us with encryption."
"The ability to share information, appointments, and agendas easily is the big value of Microsoft Exchange."
"Provides unlimited storage for our mailbox."
"Technical support is good."
"Scalability-wise, I rate the solution a ten out of ten."
"Microsoft Exchange is a very well-priced solution."
 

Cons

"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 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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"Customer service is not always helpful."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"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."
"The tool is not easy to use. Every person has to have at least administration-level experience to use the tool."
"It is important to have the updated version for scalability."
"For the next release, there are some features on the cloud-based Exchange that aren't included on-prem. It would be great if these features were made available in the next release. For instance, integration between Exchange and its on-prem calendar is not available for the on-prem solution."
"Exchange can be a little finicky, sometimes, or flakey."
"If it was the same product, and slightly cheaper, that would be amazing."
"Areas of Microsoft Exchange that have room for improvement could use some deeper thinking."
"One thing for improvement would be to have an offline version of Exchange available for use if our connection goes down."
"It's not always the finest solution in terms of integration with products that are not from Microsoft. It integrates very well with Microsoft products but not with third-party products."
 

Pricing and Cost Advice

"There are various licensing plans available based on geographic zone."
"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 is inexpensive which is its main benefit."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"The solution is priced well."
"Pricing and licensing is very competitive and in some cases, cheap."
"Costs far less than other solutions."
"I would rate the pricing and eight out of ten."
"The price of Microsoft Exchange is reasonable."
"The pricing is expensive."
"This solution is expensive."
"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."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."
"I don't have enough information about the licensing costs of Microsoft Exchange, but I do know that you need two types of licenses to run it. You need the product key and the client access key to activate Microsoft Exchange. This means that apart from the standard Microsoft Exchange licensing fees, you have to pay additional costs."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"It would be nice if it used less resources to run on-premise."
