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

"An effective, functional, very good tool for controlling resources at a low cost."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"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."
"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's scalable and stable."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"The solution is inexpensive which is its main benefit."
"It has great communication capabilities for team chatting and web conferences."
"It's so much of a part of what I do every day that I don't give it a lot of thought. It just works, for the most part, until it doesn't, in which case I call tech support."
"We have found the solution to be stable; there are no bugs or glitches, the performance is good, and we don't worry about it crashing or freezing."
"Microsoft Exchange is the leader in corporate communication."
"The technical support services are good."
"The platform's most valuable feature is the mailbox roles."
"The tool's most valuable feature is associated with the fact that it stands out for being beneficial for managing emails."
"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"The initial setup was straightforward and fast."
 

Cons

"The database query for creating new database and querying about activities are too simplistic."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"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 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."
"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"The cost could be cheaper."
"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."
"One major area for improvement is the need for repeated authentication when running a meeting."
"Microsoft Exchange could improve by adding artificial intelligence."
"In terms of probability, every now and then there are changes coming and going. The changes are not that frequent because every month they got updates back, so that is an issue."
"Load balancing is lacking."
 

Pricing and Cost Advice

"The license is based on the number of users."
"The solution is priced well."
"It is definitely one of the lowest price solutions."
"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."
"Pricing and licensing is very competitive and in some cases, cheap."
"Our licensing is on a yearly basis. There were no additional costs."
"The solution is inexpensive which is its main benefit."
"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."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"It would be nice if it used less resources to run on-premise."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."
"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."
"The pricing is expensive."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
