"What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs. Microsoft Exchange Online is the best product in the world for me because I don't remember any other service that's so well-accepted."
"The initial setup is straightforward and is definitely easy."
"Microsoft Exchange Online is a stable product."

"Stability has increased exponentially since 2010."
"The most valuable feature of Microsoft Exchange Online is it helps the IT department with problems."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
"The most valuable feature of Zimbra Collaboration is the cost."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The configuration is simple."
"We can control all the data in my IT infrastructure."
"The web interface is powerful and easy to use."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"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."
"Our customers sometimes have problems receiving mail."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
"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."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Although the documentation is extensive and in depth, you must familiarize yourself with it before taking full advantage of the product."
"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."
"I don't really like the response time of the web GUI for administration."
"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."
"The configuration of the solution's on-premise version is a little bit difficult, and its troubleshooting is more difficult than the installation itself."
"We'd like to see more integration with other platforms."
"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 efficiency could improved."
"I would like to see better security added to Microsoft Exchange Online in the area of phishing or spam emails."
"Using this solution is initially quite complicated."
"The antispam and antivirus features are hard to understand on mobile devices."
"The installation is not straightforward, it can take two days for the full implementation."
"There are some security issues."
"The solution could use more integration with third-party tools."
"The solution could improve by making it easier to use."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"It is good and competent, but you have to pay for video and group chat features."
