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.

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."

"It's scalable and stable."

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

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

"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."

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

"The solution is easy to manage and includes features such as smart documents and the archiving of user data."

"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

"The deployment is a plug-and-play process."

"The product works very well."

"It is easy to set up."

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

"Microsoft Exchange is a user-friendly and easy-to-deploy solution, which is beneficial for handling emails even without professional support."

"Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."

"The platform's most valuable feature is the mailbox roles."

"I find the desktop version of Microsoft Exchange looks better than the online version. You can make it a white background. You might be able to make the online background white, but I have no idea how to do that. I know how to do it only on the desktop version"

More Microsoft Exchange pros

Cons

"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."

"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."

"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."

"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."

More IceWarp cons

"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."

"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."

"In terms of probability, every now and then there are changes coming and going. The changes are not that frequent because every month they got updates back, so that is an issue."

"When we started using Exchange on the cloud, we had a lot of initial problems relating to our main database and we also experienced issues with the accidental deletion of inboxes, amongst other things. In fact, many of the files we had moved to the cloud had disappeared. There also seems to be a problem with the retention of information."

"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."

"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."

"The cost could be cheaper."

"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."

More Microsoft Exchange cons

Pricing and Cost Advice

"Our licensing is on a yearly basis. There were no additional costs."

"The license is based on the number of users."

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

"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."

"Costs far less than other solutions."

"The solution is priced well."

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

"There are various licensing plans available based on geographic zone."

More IceWarp pricing and cost advice

"The product pricing is reasonable if you utilize its full suite of features."

"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."

"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."

"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."

"It's a little bit 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."

"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."

"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
