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.

A good solution for large enterprises, but is expensive when compared to other solutions
Regarding the decision of increasing the number of users, it depends on the organization's choice, whether to opt for CapEx or OpEx. Both options involve expenses over the years. Building an in-house Exchange solution requires investing in hardware, storage, connectivity, and administrative resources. Office 365 shifts the budget solely to OpEx as a subscription service. Scalability is another factor. Starting a new company favors Office 365 due to cost efficiency. As the organization grows, the choice depends on available resources and technical expertise. An internal Exchange setup is feasible with skilled engineers, while Office 365 suits those lacking in-house resources.

Quotes from Members

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

Pros

"The solution's voice services work well for our company."
"IceWarp has multiple applications that are easy to use for many people."
"The solution has a very good log-in to the UI when compared to other solutions."
"It has great communication capabilities for team chatting and web conferences."
"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."
"The groupware module is the most valuable feature."
"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."
"We have found it to be a stable solution. It is scalable and easy to install."
"The initial setup is very simple."
"Microsoft Exchange is stable."
"I find Exchange's basic mail features to be highly valuable."
"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"Communication is the most valuable feature of the solution."
 

Cons

"Our customers sometimes have problems receiving mail."
"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."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"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 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."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"The solution needs improvements in security, particularly regarding document management."
"We are not able to use Microsoft Teams due to connection issues. Thus, the product integration with Teams could be improved."
"Load balancing is lacking."
"From a security perspective, Microsft Exchange can be improved. All that needs to be added is security, but that's an internal hierarchical problem from the product itself and not the end-users."
"The filtering of spam needs significant improvement, as many spam emails are not getting detected."
"The only thing that could be improved is the pricing."
"Microsoft Exchange could improve by being more secure. We are always looking to have more security."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"They could improve on the search function, it takes too much time."
 

Pricing and Cost Advice

"The solution is priced well."
"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."
"Pricing and licensing is very competitive and in some cases, cheap."
"I would rate the pricing and eight out of ten."
"There are various licensing plans available based on geographic zone."
"The solution is inexpensive which is its main benefit."
"Our licensing is on a yearly basis. There were no additional costs."
"The license is based on the number of users."
"Its price is okay."
"The product is quite cheap."
"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."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The platform has a reasonable price."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"Its price is fair."
"It is not expensive."
