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

"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."
"It has great communication capabilities for team chatting and web conferences."
"It's scalable and stable."
"If you have a small to medium business and you require a professional collaboration server that focuses on the main services of emails and calendar scheduling, I recommend IceWarp."
"The solution is inexpensive which is its main benefit."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"IceWarp offers very extended cross-platform communication solutions."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"It has a feature that allows you to retain an email and recover it as an administrator. When you activate this feature, even if a user deletes an email, the email is still in the system, and we can retrieve it as an administrator. It is a very useful function. We turn this feature on for some of the mailboxes because we need to keep all the records. I like the way emails are classified in this solution. It makes it really easy to take a look at the most important messages. This is a really good functionality. Some of the emails directly exchanged with you are marked as important and shown in one tab, and everything else is in another tab. We usually don't have any issue with Exchange. It can be integrated with different solutions."
"Now, we manage to serve almost 99% of the information."
"It gives me benefit in terms of integration with other services such as SharePoint, Microsoft Teams, and OneDrive, and it makes my work much easier."
"It's very well integrated with OneDrive and Teams Calendar."
"Our customers are satisfied with the features included in Microsoft Exchange."
"Exchange is a robust system that is well suited for an enterprise environment."
"It is a product that is simple to manage, and easy to use."
 

Cons

"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Our customers sometimes have problems receiving mail."
"The Exchange compatibility mode is rather limited."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"The solution needs improvements in security, particularly regarding document management."
"Customer service is not always helpful."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"One major area for improvement is the need for repeated authentication when running a meeting."
"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."
"The product or service could be improved in terms of Microsoft Outlook client compatibility."
"Microsoft Exchange could improve the price."
"The solution could be more secure."
"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."
"The main problem with Microsoft products is that we're constantly required to install patches and fixes."
"Areas of Microsoft Exchange that have room for improvement could use some deeper thinking."
 

Pricing and Cost Advice

"The solution is inexpensive which is its main benefit."
"There are various licensing plans available based on geographic zone."
"It is definitely one of the lowest price solutions."
"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."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"Our licensing is on a yearly basis. There were no additional costs."
"The license is based on the number of users."
"I would rate the pricing and eight out of ten."
"It is not expensive."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"This solution is expensive."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"We pay for the license annually."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"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."
"It's a little bit expensive."
