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

"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."

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

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

"The groupware module is the most valuable feature."

"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."

More IceWarp pros

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

"Technical support is good."

"Exchange is easy to use. It also has a built-in calendar for all the stuff I'm supposed to be looking at and doing. Exchange tells you if you have a doctor's appointment or a scheduled call. It also has a place to store and manage your contacts. If I want to add a new contact, it will put in information about that contact stored anywhere within the Microsoft Suite."

"The ability to share information, appointments, and agendas easily is the big value of Microsoft Exchange."

"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."

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

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

"The technical support services are good."

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."

"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."

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

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

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

"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."

"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."

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

More IceWarp cons

"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."

"In terms of configuring the product, that's definitely an area in which they can make some improvements on."

"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 could improve the price."

"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."

"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."

"It is important to have the updated version for scalability."

"The default storage capacity is too small."

More Microsoft Exchange cons

Pricing and Cost Advice

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

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

"Costs far less than other solutions."

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

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

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

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

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

More IceWarp pricing and cost advice

"The platform has a reasonable price."

"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."

"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."

"Licensing fees are paid monthly."

"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."

"It's a little bit expensive."

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

"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."
