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 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."
"IceWarp has multiple applications that are easy to use for many people."
"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."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution has a very good log-in to the UI when compared to other solutions."
"The groupware module is the most valuable feature."
"The solution's voice services work well for our company."
"IceWarp offers very extended cross-platform communication solutions."
"It is easy to set up."
"Customers can benefit from this new pricing model because it's expensive, and now with the subscription, they can budget for this."
"The most used feature of Microsoft Exchange is the email capability, especially since it integrates with the calendar."
"Technical support is good."
"The most valuable feature of Microsoft Exchange is the collaboration tools."
"The initial setup is very simple."
"Microsoft Exchange has good performance and is user-friendly."
"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."
 

Cons

"Customer service is not always helpful."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The database query for creating new database and querying about activities are too simplistic."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"I think it could be more scalable."
"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."
"More AI features would be good."
"Microsoft Exchange and other Microsoft solutions like Office 365 need to provide more detailed information for customers regarding the features and functionalities included in their plans, as some features are only available at an additional cost."
"Exchange's management could be improved a bit, and its troubleshooting tools are limited at times."
"Unfortunately, the quality of support is very low."
"I would like to see the search capability of the Outlook client improved"
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
 

Pricing and Cost Advice

"There are various licensing plans available based on geographic zone."
"Our licensing is on a yearly basis. There were no additional costs."
"The solution is inexpensive which is its main benefit."
"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 would rate the pricing and eight out of ten."
"The solution is priced well."
"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."
"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."
"The price of Microsoft Exchange is reasonable."
"Microsoft Exchange is an inexpensive application."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"The product pricing is reasonable if you utilize its full suite of features."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"The platform has a reasonable price."
