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.

Offers flexibility and cost-effectiveness with multiple service options but could improve support and mobile features
There are many things to consider about email management in Microsoft Exchange Online. The online management is good, the storage is sufficient, and we use most of the features such as the custom rules in Microsoft Exchange Online, which we cannot find in any other email solution. That is a very good option, as we have many options to create custom rules in Microsoft Exchange Online. Regarding security features in Microsoft Exchange Online, we also use Defender for Exchange which includes the basic Exchange Online protection that has spam and threat controls. The use of Defender is beneficial for our security. The flexibility of choosing plans in Microsoft Exchange Online is good. We have chosen the best plan for our use, including multiple licenses such as plan one and business basics, which leads us towards cost-effectiveness, and the pay-as-you-go option is more flexible. Microsoft Exchange Online is very scalable.

"Customer service is not always helpful."
"The Exchange compatibility mode is rather limited."
"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 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 is a bit more expensive than other solutions."
"The solution's pricing is reasonable."
"We pay a yearly licensing fee for the solution."
"This is an expensive solution."
