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.

Reliable email service has supported consistent communication and improved user training
I do use Cisco Secure Email, Grafis, and Proofpoint Email Protection when needed, but we were using Proofpoint before, and we are no longer using it. I am currently using Microsoft Exchange as our email solution. We are a client of Microsoft; there is no partnership between my company and Microsoft. My experience with Microsoft Exchange is as good as the generic email. I do not use Microsoft Exchange to synchronize emails across devices, and it is not part of my workflow. The protocols I mostly use with Microsoft Exchange for integration are SMTP. I do not use the shared calendars feature in Microsoft Exchange. Data loss prevention is something we are not really using or utilizing at the moment. My overall review rating for Microsoft Exchange is 8.

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 inexpensive which is its main benefit."
"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."
"IceWarp has multiple applications that are easy to use for many people."
"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 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."
"As the license of our company is very affordable per year and per user, and considering the almost-zero administration needs, I would say that the cost is returned in the first three months, compared to other solutions."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"The functionality on the user side is quite good, and Exchange provides an excellent platform for collaboration between users."
"The most valuable feature of Microsoft Exchange is its ease of use."
"Microsoft Exchange is highly stable for the end-user systems. When we move to Office 365, it will be even more stable even. There's less administration required and it's very robust. We are really quite happy in using that."
"We have found it to be a stable solution. It is scalable and easy to install."
"In general, this is a good product and I am happy with it."
"The most valuable features of Microsoft Exchange are it is always online and has broad email and file-sharing capabilities."
 

Cons

"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"The Exchange compatibility mode is rather limited."
"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 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."
"Load balancing is lacking."
"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"The pricing could be better, and it could have an easier implementation."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"They could continue to improve the consolidation and integration of mailbox services to make them more flexible, easier to deploy, and more manageable."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"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."
 

Pricing and Cost Advice

"The solution is priced well."
"The solution is inexpensive which is its main benefit."
"I would rate the pricing and eight out of ten."
"Pricing and licensing is very competitive and in some cases, cheap."
"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."
"Costs far less than other solutions."
"Our licensing is on a yearly basis. There were no additional costs."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Microsoft Exchange is a very well-priced solution."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"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."
"We pay for the license annually."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The product is quite cheap."
"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."
