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 solution's voice services work well for our company."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"It has great communication capabilities for team chatting and web conferences."
"The groupware module is the most valuable feature."
"It's scalable and stable."
"An effective, functional, very good tool for controlling resources."
"IceWarp has multiple applications that are easy to use for many people."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"This solution makes it very easy to receive and detect problems about the mail flow and offers very good reporting. In general, it's very easy to manage the organization's mailboxes."
"The solution is stable."
"The benefits are widespread and effective communication. We use Microsoft Teams for meetings within and outside our organization. Additionally, Teams can be used for chat, allowing us to track communication and see user activity"
"A valuable feature of the solution is its global usability."
"Microsoft has many consultants who can provide support."
"When you used to write to someone, you would often begin typing their name and their email address would appear; you would simply click and you would have the correct email address. That has been working for a while, but having the location address appear was a pleasant surprise. It was amazing."
"It has helped us because we don't have to worry about servers crashing."
"It is a fantastic solution."
 

Cons

"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."
"The solution needs improvements in security, particularly regarding document management."
"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."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"It is difficult to disable user rights on the console so some users accidentally delete their documents or user details."
"Our customers sometimes have problems receiving mail."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"It should integrate better with social media formats."
"I would like to make the solution more user-friendly."
"In terms of areas for improvement, I think Microsoft could enhance security. Right now, there are limited options for security within Exchange Online, and much of it relies on third-party security and compliance tools. I'd like to see more security features directly integrated. One specific area that needs improvement is the configuration of SMTP for third-party applications. It's challenging to manage without an on-premise SMTP server, and this is an issue many organizations face, including ours. If Microsoft could offer better SMTP configuration for third-party applications within Exchange Online, it would greatly benefit us."
"The cost is very high, and not every customer can afford licenses."
"Using this solution is initially quite complicated."
"There is room for improvement in terms of security, as it could be better."
"I would like to let new users know that there are challenges regarding user provisioning, HRMS and the AD. Also, the data migration integrity needs to be checked in terms of the old data."
"I don't like it in general. It sort of has that Microsoft flavor to it, which is just the style they use and the way they color things and lay them out."
 

Pricing and Cost Advice

"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."
"I would rate the pricing and eight out of ten."
"It is definitely one of the lowest price solutions."
"There are various licensing plans available based on geographic zone."
"The solution is priced well."
"Our licensing is on a yearly basis. There were no additional costs."
"Pricing and licensing is very competitive and in some cases, cheap."
"Costs far less than other solutions."
"I find it reasonably priced."
"This solution requires a license."
"It is a cluster solution."
"The price of Microsoft Exchange Online security could improve. The overall price of the solution is reasonable."
"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."
"They have raised their prices, and obviously, it hits our customers. Some of them are deciding to step back from Office 365. For customers who have bought the annual subscription, they are moving to the monthly subscription."
"Microsoft solutions are expensive."
"The price is not competitive."
