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

"It's scalable and stable."
"An effective, functional, very good tool for controlling resources."
"It has great communication capabilities for team chatting and web conferences."
"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."
"IceWarp has multiple applications that are easy to use for many people."
"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."
"The solution's voice services work well for our company."
"The solution is stable."
"The most valuable features of Microsoft Exchange Online are spam filtering, 50 GB of email storage, good integration with Outlook, and ease of management."
"The most valuable feature of Microsoft Exchange Online is if you have people that are geographically distributed from each other is good. For example, if you have people in the United States, Europe, Africa, Asia, and Australia, having an online solution works best because then you can reach the scale of the data centers that are available by Microsoft. Additionally, if you're only going to have two to three people using the solution the cost is a lot less than having an onsite server and licensing. It is highly beneficial in these areas."
"I would rate Exchange Online's stability nine out of ten."
"I have not had issues with stability of the product."
"Microsoft Exchange Online has great functionality."
"Tech support has been great, when necessary."
"Microsoft Exchange Online's resiliency is its most valuable feature."
 

Cons

"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 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."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"The solution needs improvements in security, particularly regarding document management."
"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 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."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"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."
"The support could improve their response time and sometimes the phone lines are not clear because of static or noise. However, the agents are knowledgeable and very helpful."
"The mail-blocking feature is not great and could be improved."
"The integration could be better if it could integrate well with other products and software."
"The pricing could be a bit lower."
"I would like to have the option to have my electronic signature posted on my emails by default. I am able to add it manually but cannot get it by default."
"In the past, we had issues with DB in mailboxes."
"I don't really like the response time of the web GUI for administration."
 

Pricing and Cost Advice

"The solution is inexpensive which is its main benefit."
"I would rate the pricing and eight out of ten."
"The license is based on the number of users."
"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."
"Costs far less than other solutions."
"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."
"It is a reasonable solution."
"The product is very cheap."
"Our organization pays for a corporate license to use the solution."
"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."
"The pricing for Microsoft Exchange Online is quite reasonable, in my opinion. Many licensing options are available so that we can choose based on the customer's needs. For example, if a customer only requires mailbox features, we can recommend Plan One or Plan 2. We can suggest an E3 or E5 license if they need the entire Office suite. There are also premium subscriptions for enterprise customers, offering additional security features. Overall, I don't find the pricing costly because Microsoft provides many features and security capabilities, making it reliable for all customers, depending on their requirements."
"The pricing could be improved."
"The license for the solution is cheap, but it could be more affordable in the long term."
"Initially, we had issues with the licensing agreement, but we worked it out with Microsoft."
