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.

Effective collaboration achieved with versatile features and good customer service
There are always improvements needed. My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary. I am not an IT person; I am an educator, a trainer, a user. I want to get the work done. However, I find that the Exchange Server and possibly the way our company has set up access permissions require extensive programming knowledge. It might take six to eight weeks to get a programmer's time to build something, whereas I can use something like Smartsheet that will do everything I want without needing a programmer. Smartsheet is more end-user friendly compared to a Microsoft product. Microsoft believes an expert IT person should manage everything, however, I want to manage things on my own in a simplified way. That is not easy using the Exchange Server or Microsoft Office. It is not end-user friendly for development, and a programmer is needed. Once set up, using them as an end-user is fine. I find that the automations are not robust, and the FedRAMP systems are not robust. I have a few issues with Exchange and Office, but there's nothing I can do about it.

Quotes from Members

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

Pros

"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"It has great communication capabilities for team chatting and web conferences."
"The solution's voice services work well for our company."
"The groupware module is the most valuable feature."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"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."
"An effective, functional, very good tool for controlling resources."
"The solution has a very good log-in to the UI when compared to other solutions."
"There are many valuable features such as email, calendar, and the ability to share your calendar and documents with coworkers. Knowing that the emails go through the EOP filtering service is nice as well."
"The reliability factor is high."
"One of my favourite features is the Microsoft Calendar, which we use for booking appointments, scheduling calls, and managing resource rooms and devices. The Online Mailbox feature is also crucial because it allows us to communicate effectively within and outside the organization, contributing to our business growth."
"The solution is quite convenient because you can access the web version anywhere."
"The most valuable feature is the cloud environment."
"Microsoft Exchange Online is an easy-to -use email solution."
"It's pretty reliable. We haven't had any issues with it."
"Microsoft Exchange Online is easy to use. You have a common storage where people can store documents. It also helps with version control."
 

Cons

"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."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"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."
"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."
"Microsoft Exchange Online can improve message delivery. There are times we receive a message that the email failed to be delivered, and there is no reason given. We sometimes have emails that are flagged as spam that are not. We cannot do anything about it because it's not managed by us, it's managed by Microsoft."
"It will be much better if the tool is integrated with OpenAI."
"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 support from the vendor is fine. However, it could be faster, and some of the agents could be more knowledgeable, but it is a large solution, there's a lot of information that the agents have to work with. I can't always expect when I get connected to the first-level agent that they will know absolutely everything. Sometimes there's no replacement for pure experience."
"Exchange Online has issues with its mail flow and content search."
"We use different software for email spoofing filters and similar functions because Exchange is quite limited in this area."
"The integration could be better if it could integrate well with other products and software."
"The stability of the solution has room for improvement."
 

Pricing and Cost Advice

"It is definitely one of the lowest price solutions."
"The solution is inexpensive which is its main benefit."
"The solution is priced well."
"Pricing and licensing is very competitive and in some cases, cheap."
"There are various licensing plans available based on geographic zone."
"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."
"Our licensing is on a yearly basis. There were no additional costs."
"Costs far less than other solutions."
"We pay a yearly licensing fee for the solution."
"The product is very cheap."
"Microsoft Exchange Online is an affordable solution."
"The pricing could be improved."
"I think it's just awesome. There's no argument about how much value you get on the per user, for user expenditure. It's really great, I don't have any issues with it. I think it's excellent."
"There is an annual enterprise subscription to use Microsoft Exchange Online. The price is reasonable."
"There is a license for Microsoft Exchange Online and I have information on that, but there have been so many changes to the licensing and it's a completely different story nowadays. Microsoft has been pushing users to buy a package of products under one license. Users are becoming more dependent on Microsoft rather than independent, that you can't decide anymore, and from my point of view, that is bad."
"I have no opinion."
