Efficient email management with seamless integration
We previously used Microsoft Exchange but have moved to an MDN email solution due to cost and user growth Microsoft Exchange is a user-friendly and easy-to-deploy solution, which is beneficial for handling emails even without professional support. It is effective in managing email integration…

One of the premium features was customized rooms tailored to the collaboration needs
Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"The exchange functionalities are good."
"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"Scalability-wise, I rate the solution a ten out of ten."
"The initial setup is quite a straightforward process. I don't think it is a very complicated solution. Plenty of things could be more complex, but the ordinary, general settings are quite simple."
"Its technical implementation is quite good, it is stable and can be accessed through all kinds of devices, and it performs pretty well."
"Microsoft Exchange is a very well-priced solution."
"It is a very stable tool...It is a very scalable tool."
"The configuration is simple."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
"Despite sticking with Gmail for over a decade in terms of business, Zimbra have impressed me with some other aspects as well; if the time comes, I would prefer Zimbra to my current solution."
"For an SMB, it is a recommendable email solution."
"Zimbra Collaboration's sharing features are most valuable."
"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 product is very stable."
 

Cons

"They keep making all these changes, and our system was down for four or five days."
"The calendar integration in Exchange is not that great. The email features are okay, but it doesn't integrate well with the calendar and appointments, especially Zoom appointments. It integrates fine with Microsoft Teams, but Zoom is a challenge."
"The product or service could be improved in terms of Microsoft Outlook client compatibility."
"I think it could be more scalable."
"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."
"Microsoft Exchange's customer support could be faster and more knowledgeable."
"The only thing that could be improved is the pricing."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The solution could improve by making it easier to use."
"Zimbra Collaboration's video conferencing could be improved."
"It would be great if a group chat feature were created to allow for a team environment."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"There are some security issues."
"File sharing permissions with Nextcloud integration need improvement."
"They should enhance its online meeting features."
 

Pricing and Cost Advice

"It would be nice if it used less resources to run on-premise."
"The product pricing is reasonable if you utilize its full suite of features."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."

"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The price of the solution is low."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
