Executive SummaryUpdated on May 21, 2025

Microsoft Exchange Online and IceWarp offer contrasting solutions in the realm of business communication platforms. Based on the reviews, Exchange Online appears to have the upper hand due to its robust integration capabilities and user-friendly design, although IceWarp's competitive pricing and standalone versatility remain attractive.

Features: Microsoft Exchange Online is known for its intuitive user interface, strong collaboration features like email and calendar sharing, and seamless integration with the Microsoft ecosystem, which enhances stability and reliability. IceWarp, however, offers versatile cross-platform solutions with valuable features such as TeamChat for efficient communication and collaboration but lacks in advanced document management. It provides essential tools that support cost-effective communication strategies for businesses.

Room for Improvement: Users of Exchange Online report difficulties with migration and integration with non-Microsoft products and mention concerns over security vulnerabilities, complex configuration, and high pricing. There is also a desire for enhanced anti-spam and anti-malware tools. IceWarp users note issues with user rights management, cumbersome master databases, and express the need for improvements in security and documentation as well as more responsive support services.

Ease of Deployment and Customer Service: Exchange Online's strong cloud presence offers consistent performance across public and hybrid environments, however, support responses can be slow. IceWarp offers flexibility with on-premises and private cloud options, which is appealing for those seeking cost-effective solutions. While customer service is generally appreciated, users note that faster support and better integration options are desired.

Pricing and ROI: Pricing for Exchange Online can be challenging for some users due to complex licensing and bundling multiple services, though it provides significant ROI through improved business efficiencies. IceWarp's pricing is more attractive as it is often lower than competitors like Google and Microsoft. This cost advantage makes it appealing for businesses looking to cut costs while maintaining essential communication features, offering significant ROI through its affordability.

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.

Effective collaboration achieved with versatile features and good customer service

There are always improvements needed. My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary. I am not an IT person; I am an educator, a trainer, a user. I want to get the work done. However, I find that the Exchange Server and possibly the way our company has set up access permissions require extensive programming knowledge. It might take six to eight weeks to get a programmer's time to build something, whereas I can use something like Smartsheet that will do everything I want without needing a programmer. Smartsheet is more end-user friendly compared to a Microsoft product. Microsoft believes an expert IT person should manage everything, however, I want to manage things on my own in a simplified way. That is not easy using the Exchange Server or Microsoft Office. It is not end-user friendly for development, and a programmer is needed. Once set up, using them as an end-user is fine. I find that the automations are not robust, and the FedRAMP systems are not robust. I have a few issues with Exchange and Office, but there's nothing I can do about it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"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."

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

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

More Microsoft Exchange Online pros

Cons

"Our customers sometimes have problems receiving mail."

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

"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."

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

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

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

More IceWarp cons

"Cloud security is always a concern and the solution can always increase their security."

"There is room for improvement in terms of optimization."

"The problem with Exchange is that the attributes aren't flexible enough. I'd like to see more interaction with Office 365 and tighter integration between on-prem Exchange and Exchange Online. There's still a disconnect between mailboxes and the cloud."

"The stability of the solution has room for improvement."

"When we need to purchase additional licenses for additional users, the process is slow."

"The support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience."

"What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like. Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement. I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one."

"The demo version we were provided had issues with emails bouncing or being delayed."
