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.

Integrated email security has improved phishing response and provides better threat visibility
Microsoft Exchange Online could be improved with more intuitive administration workflows, better troubleshooting visibility, and simpler mail flow analysis for complex environments. We would also appreciate more granular reporting, faster access to detailed message tracking data, and improved alerting around suspicious mailbox activity to help security and messaging teams investigate issues more efficiently. One area where Microsoft Exchange Online could improve is the administrative user experience. Some advanced mail flow, compliance, and troubleshooting tasks still require navigating multiple Microsoft portals. A more unified management interface and deeper integration visibility across Exchange, Defender, and Microsoft 365 security tools would make day-to-day operations more efficient for administrators and SOC teams.

Quotes from Members

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

Pros

"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."
"IceWarp offers very extended cross-platform communication solutions."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"The solution's voice services work well for our company."
"IceWarp has multiple applications that are easy to use for many people."
"An effective, functional, very good tool for controlling resources at a low cost."
"It has great communication capabilities for team chatting and web conferences."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"Microsoft Exchange Online has great functionality."
"Integration with the Microsoft applications is the key for us."
"The solution is stable."
"I am using Microsoft Exchange Online for efficient mail deployment and additional file security, and we can also do collaboration."
"The most valuable feature is the cloud environment."
"The features and flexibility in Microsoft Exchange Online cannot be found in any other email solutions—everything we need is there, and we do not have any complaints about it."
"It helps us manage the email focus from our side."
"It has helped us because we don't have to worry about servers crashing."
 

Cons

"Customer service is not always helpful."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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."
"Our customers sometimes have problems receiving mail."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"Support is not good and it is challenging to receive a timely response."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"The ActiveSync services and the mapping services could be improved."
"The cost is more expensive than other online email solutions."
"For non-technical people, some configurations might be a little bit difficult. We can use it on our laptops or our portable devices like mobiles and others gadgets, but we have had repeated problems with syncing. That is, when using different gadgets and devices, there are issues with syncing. The configuration could definitely be improved."
"The interface is a bit confusing."
"I would prefer an anti-malware functionality in at least the basic version."
"This is a single solution and if it's the first time you've used Exchange, it's extremely difficult to get users onboard because it's much more complicated than you'd have with 365, for example."
"I would like to see better security added to Microsoft Exchange Online in the area of phishing or spam emails."
"The stability of the solution has room for improvement."
 

Pricing and Cost Advice

"Our licensing is on a yearly basis. There were no additional costs."
"It is definitely one of the lowest price solutions."
"The license is based on the number of users."
"Pricing and licensing is very competitive and in some cases, cheap."
"The solution is priced well."
"I would rate the pricing and eight out of ten."
"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 inexpensive which is its main benefit."
"The product is expensive and has an annual subscription."
"Microsoft Exchange Online is an affordable solution."
"This solution requires a license."
"I think that the price is a little high, especially considering that Google have a similar, free email solution."
"I pay approximately $120 or $150 per year, and as long as I pay that amount, they will do regular updates so that I always have the most recent and greatest version of the application."
"The pricing is really high. It's higher compared to other services."
"The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use."
"I am using Office 365 and Microsoft Exchange Online comes as the package. It cost approximately $13 per month."
