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

"It's scalable and stable."

"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."

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

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

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

More IceWarp pros

"The initial setup is straightforward and easy to configure."

"Exchange Online doesn't just do email, it allows for collaboration with inbuilt chat and calling facilities and document sharing."

"It is a stable, and highly scalable product."

"The most valuable feature of Microsoft Exchange Online is it helps the IT department with problems."

"The solution is stable."

"It's easy to use and there is more integration."

"I enjoy not having to maintain the local infrastructure, local servers, local whatever. You use the software and don't have to worry about the details."

"The online version is faster, as it is a cloud instance. We can have massive mailbox capacity: 100 GB per user, which is huge. We can't provision such capacity internally, as the company would get burnt out paying for mailbox storage."

More Microsoft Exchange Online pros

Cons

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

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

"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."

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

"Our customers sometimes have problems receiving mail."

"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."

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

More IceWarp cons

"In terms of areas for improvement, I think Microsoft could enhance security. Right now, there are limited options for security within Exchange Online, and much of it relies on third-party security and compliance tools. I'd like to see more security features directly integrated. One specific area that needs improvement is the configuration of SMTP for third-party applications. It's challenging to manage without an on-premise SMTP server, and this is an issue many organizations face, including ours. If Microsoft could offer better SMTP configuration for third-party applications within Exchange Online, it would greatly benefit us."

"Microsoft Exchange Online could improve the management usage, it should be more user-friendly."

"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."

"I would rate Exchange Online's stability eight out of ten - it has room for improvement."

"This solution involves a lot of work for an administrator. It is not always easy to find exactly what you are looking for within the system."

"When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid."

"I would like to have the option to have my electronic signature posted on my emails by default. I am able to add it manually but cannot get it by default."

"The UI could be improved to look more like the desktop version for ease of use."

Pricing and Cost Advice

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

"Costs far less than other solutions."

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

"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 solution is priced well."

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

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

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

More IceWarp pricing and cost advice

"The pricing is based on a yearly contract and a floating license option is offered."

"The price of the solution could be less expensive."

"It is a cluster solution."

"I am using Office 365 and Microsoft Exchange Online comes as the package. It cost approximately $13 per month."

"The price of Microsoft Exchange Online security could improve. The overall price of the solution is reasonable."

"The cost is around $12 to $16 per user."

"I would give the cost a five out of ten."

"This is an expensive solution."
