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 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."

"An effective, functional, very good tool for controlling resources."

"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."

"It's scalable and stable."

"The solution has a very good log-in to the UI when compared to other solutions."

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

"Its price is the most valuable. It is definitely one of the lowest price solutions."

"IceWarp has multiple applications that are easy to use for many people."

More IceWarp pros

"Exchange is very scalable, it's one of the most important things about this software."

"It is user friendly."

"This solution handles all of our primary functionality including email, message delivery, message archiving and calendars."

"Scalability-wise, I rate the solution a ten out of ten."

"The initial setup is easy."

"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."

"Now, we manage to serve almost 99% of the information."

"With the cloud coming in, scalability is not an issue even for Microsoft."

More Microsoft Exchange pros

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."

"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 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."

"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."

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

More IceWarp cons

"Exchange can be a little finicky, sometimes, or flakey. Last week, for example, I had gone into my calendar to check on some briefings that I had established, and then went back into my inbox, and suddenly the view had changed. I had no idea what it was that I had done, and I couldn't figure out how to get that view back. I took a productivity hit as a result of that, trying to fix it, due to the fact that it just wasn't what I wanted. It wasn't what I was used to working with. Two different tech support people had to work with me in order to get the view back to what I wanted just so I could be productive."

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

"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."

"Microsoft could improve on Exchange's hybrid deployment or HCW. They need to improve on that because I was having many issues with HCW in our environment at times."

"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."

"The security features could be improved. There should be a better policy management system."

"They could offer simultaneous features for Exchange Online and on-premises versions. Specific features such as litigation hold and audit setups should be available on-premises."

"After 2022, users of Microsoft Exchange have to migrate mailboxes to Microsoft Exchange Online, and what I'd like to improve is for Microsoft to publish more on-premise versions for customers using Microsoft Exchange. Having more security is another room for improvement in the solution, particularly for mailboxes that develop the Exchange Edge rule to protect internal mailboxes. What I'd like to see from Microsoft Exchange in the future is for Microsoft to still update the latest, existing version which is 2022. I'd like Microsoft to still push more cumulative updates for Microsoft Exchange 2022."

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."

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

"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 is priced well."

"It is definitely one of the lowest price solutions."

More IceWarp pricing and cost advice

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

"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."

"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."

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

"Microsoft Exchange is an inexpensive application."

"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."

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

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