Executive SummaryUpdated on May 21, 2025

Microsoft Exchange and IceWarp compete in the enterprise communication solutions category. Microsoft Exchange maintains an edge with its comprehensive enterprise-level integrations and features, demonstrating strong capabilities in providing robust solutions for large businesses.

Features: Microsoft Exchange offers extensive integration capabilities, calendar synchronization, and email retention management. Its robust toolbox for third-party integration and seamless collaboration tools stand out. IceWarp is known for its cross-platform compatibility, cost-effective communication solutions, and features such as team chat, file sharing, and conferencing collaboration.

Room for Improvement: Microsoft Exchange needs to improve storage management, integration with non-Microsoft products, and simplify its complex licensing. Enhancing its security features would also be beneficial. IceWarp could improve its mobile integration, mailing list function, and enhance security features while simplifying its administrative processes.

Ease of Deployment and Customer Service: Microsoft Exchange offers a variety of deployment options including on-premises, cloud, and hybrid models, though it requires comprehensive technical support. IceWarp provides similar deployment flexibility and is noted for its ease of use but faces challenges with customer service consistency and documentation.

Pricing and ROI: Microsoft Exchange's pricing is higher, reflecting its enterprise capabilities and comprehensive feature set. This pricing structure is generally suited for larger organizations. IceWarp provides aggressive and flexible pricing appealing to smaller enterprises, offering essential features within a budget-friendly framework. This makes IceWarp an attractive option for smaller companies concerned with costs.

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.

Helps with email services and communication with internal and external contacts

Everything is useful. The only useful thing Microsoft Exchange could do is give us more of a discount on pricing because it's so expensive. Regarding the calendaring functions of Exchange, there is a problem when scheduling an event for the whole day. When you click the whole day event, the scheduling doesn't really work. For example, if I schedule a meeting with you and block your whole day, instead of just putting a time from morning to afternoon, other people can still block your time, which results in double booking. It's kind of a bug that allows people to double-book. So, the scheduling isn't working properly yet. We also faced challenges with backup services. You need to use a third-party backup solution to back up the whole Exchange server properly. You can't use the native Windows backup services. It's like they're forcing me to buy another product, which means additional costs. The backup solution and the double booking issues. If Microsoft Exchange can fix these two things, then it will be very good.

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 groupware module is the most valuable feature."

"It's scalable and stable."

"The solution's voice services work well for our company."

"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."

"It has great communication capabilities for team chatting and web conferences."

"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 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."

More IceWarp pros

"Microsoft Exchange is highly stable for the end-user systems. When we move to Office 365, it will be even more stable even. There's less administration required and it's very robust. We are really quite happy in using that."

"Exchange's interface is good. All of our engineers like it and are accustomed to using it."

"It's an excellent product from Microsoft. It provides more flexibility to the end-users. As it's connected with Teams, it also enables collaboration."

"It is a very stable tool...It is a very scalable tool."

"The initial setup is quite a straightforward process. I don't think it is a very complicated solution. Plenty of things could be more complex, but the ordinary, general settings are quite simple."

"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."

"Microsoft Exchange has good performance and is user-friendly."

"The search tools are good."

More Microsoft Exchange pros

Cons

"The solution needs improvements in security, particularly regarding document management."

"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."

"Support should be improved. Most of the time, the queries are not resolved within the SLA."

"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."

"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."

"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."

"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."

"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."

More IceWarp cons

"If it was the same product, and slightly cheaper, that would be amazing."

"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."

"The solution could be more secure."

"I do not have any notes for improvement."

"There is a problem when scheduling an event for the whole day."

"One major area for improvement is the need for repeated authentication when running a meeting."

"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."

"Microsoft Exchange could improve the archiving of emails and the performance."

More Microsoft Exchange cons

Pricing and Cost Advice

"The solution is inexpensive which is its main benefit."

"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 license is based on the number of users."

"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."

"Pricing and licensing is very competitive and in some cases, cheap."

"The solution is priced well."

"I would rate the pricing and eight out of ten."

More IceWarp pricing and cost advice

"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."

"I rate Microsoft Exchange's pricing a six out of ten."

"We can get Exchange in the cloud along with the Microsoft 365 license."

"Microsoft Exchange is a very well-priced solution."

"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."

"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."

"The pricing is expensive."

"The platform has a reasonable price."
