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

"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution's voice services work well for our company."
"It's scalable and stable."
"It has great communication capabilities for team chatting and web conferences."
"The solution has a very good log-in to the UI when compared to other solutions."
"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."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"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 functionality on the user side is quite good. Exchange provides an excellent platform for collaboration between users."
"Internal communication stability within Exchange is ensured by the stability of the internal network which is guaranteed by default."
"We've been using Exchange as an email platform. Our clients require multi-country, multi-regional email collaboration with controlled mail flow. The most valuable feature is the capability of message tracking and the protection of user data."
"The ability to share information, appointments, and agendas easily is the big value of Microsoft Exchange."
"Our customers are satisfied with the features included in Microsoft Exchange."
"It integrates well with other tools."
"The solution can scale well."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
 

Cons

"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."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The solution needs improvements in security, particularly regarding document management."
"Our customers sometimes have problems receiving mail."
"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."
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
"For new users, it might take them some time to get used to the product."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"Microsoft Exchange could improve by adding artificial intelligence."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"There is a problem when scheduling an event for the whole day."
 

Pricing and Cost Advice

"I would rate the pricing and eight out of ten."
"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."
"Our licensing is on a yearly basis. There were no additional costs."
"The license is based on the number of users."
"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's pricing is fine...I do think the tool offers value for money."
"It's working very well. There is no problem, but the price is not the best."
"Its price is fair."
"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."
"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."
"The pricing is expensive."
"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."
"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."
