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

"It is a very stable tool...It is a very scalable tool."
"The search tools are good."
"This solution handles all of our primary functionality including email, message delivery, message archiving and calendars."
"Scalability-wise, I rate the solution a ten out of ten."
"We use the solution for all communication exchanged with our team, customers, and all other internet exchanges."
"For me, it's always worked quite well, and because of that, I haven't given anything about it much thought."
"Our customers are satisfied with the features included in Microsoft Exchange."
"The functionality on the user side is quite good, and Exchange provides an excellent platform for collaboration between users."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"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."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"The backup and storage management features of Zimbra Collaboration are valuable."
"The most valuable feature of Zimbra Collaboration is the cost."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The solution is easy to implement."
 

Cons

"It doesn't work very well on a virtual machine. We had to move it around. There are also issues when you try to move it between computers."
"It's not always the finest solution in terms of integration with products that are not from Microsoft. It integrates very well with Microsoft products but not with third-party products."
"After 2022, users of Microsoft Exchange have to migrate mailboxes to Microsoft Exchange Online, and what I'd like to improve is for Microsoft to publish more on-premise versions for customers using Microsoft Exchange. Having more security is another room for improvement in the solution, particularly for mailboxes that develop the Exchange Edge rule to protect internal mailboxes. What I'd like to see from Microsoft Exchange in the future is for Microsoft to still update the latest, existing version which is 2022. I'd like Microsoft to still push more cumulative updates for Microsoft Exchange 2022."
"The default storage capacity is too small."
"Technical support could be improved. It takes you a while to get through to a technician, especially on the Microsoft side."
"Exchange can be a little finicky, sometimes, or flakey."
"Microsoft Exchange could improve the price."
"The price of Microsoft Exchange could improve, it is priced high."
"It would be great if a group chat feature were created to allow for a team environment."
"There are some bugs we found that could be fixed."
"The installation is not straightforward, it can take two days for the full implementation."
"The log files need to be improved; they need to show us more information because a lot of detail is lacking and that's not very helpful or insightful."
"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."
"The solution could improve by making it easier to use."
"It would be great if a group chat feature were created to allow for a team environment."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."

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.
