Quotes from Members

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

Pros

"We've been using Exchange as an email platform; our clients require multi-country, multi-regional email collaboration with controlled mail flow, and the most valuable feature is the capability of message tracking and the protection of user data."
"Microsoft support is very good."
"Microsoft provides you with an ease of control and management and sets certain expectations from the software that you can't have if you implement other, cheaper solutions that are likely to be more difficult to manage or that are unable to adapt to new demands."
"It gives me benefit in terms of integration with other services such as SharePoint, Microsoft Teams, and OneDrive, and it makes my work much easier."
"It's a very user-friendly application. The mail server is also valuable when compared to other services like SquirrelMail."
"It's so much of a part of what I do every day that I don't give it a lot of thought. It just works, for the most part, until it doesn't, in which case I call tech support."
"It's an excellent product from Microsoft. It provides more flexibility to the end-users. As it's connected with Teams, it also enables collaboration."
"This solution has improved the collaboration between our organization and our partners and contractors."
"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."
"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
"Good email solution and it's open-source."
"The pricing of the solution is excellent; it's a newer solution with a modern interface and dashboard, the interface itself is very responsive and easy to navigate, the initial setup is very simple and straightforward, the stability is good and keeps getting better with each new update, and the solution really does scale very easily."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"Zimbra Collaboration's sharing features are most valuable."
"The logs, troubleshooting, and tracking we have found to be the most valuable features, and when we have any issues with lost messages these features are useful because it is very easy to track and log."
 

Cons

"When we started using Exchange on the cloud, we had a lot of initial problems relating to our main database and we also experienced issues with the accidental deletion of inboxes, amongst other things."
"Exchange's management could be improved a bit, and its troubleshooting tools are limited at times."
"Microsoft Exchange needs to improve how it handles and assigns policy and security."
"Its search functionality can be better. It is currently not really easy."
"I'd like the archiving process to be faster."
"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."
"Microsoft Exchange could improve by adding artificial intelligence."
"The filtering of spam needs significant improvement, as many spam emails are not getting detected."
"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."
"There are some security issues."
"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."
"The solution could improve by making it easier to use."
"Zimbra is not very stable, but it's okay."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"Server deployment and the GUI for emails should be better."
"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."
 

Pricing and Cost Advice

"This solution is expensive."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"I have Outlook 365 Professional, and Exchange comes in the bundle with other solutions, such as Word and OneDrive. I pay for the use of the bundle monthly and I can imagine if you are a company with many licenses the pricing model would be a lot different."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."

"The solution is not expensive compared to other products."
"Zimbra Collaboration offers a good price-to-feature ratio."
"We pay yearly licenses for Zimbra Collaboration."
"When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange."
