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

"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"We have always used Exchange, that's a strategic choice for our company, and we are confident in Microsoft because their support is always there for us."
"It integrates well with other tools."
"It's user-friendly."
"Because I have a lot of experience using Exchange, I would rate it between eight and nine out of ten."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"It is user friendly."
"Microsoft Exchange is stable."
"The web interface is powerful and easy to use."
"The most valuable feature of Zimbra Collaboration is the cost."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"Network NG Modules are valuable to us."
"For an SMB, it is a recommendable email solution."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"We can control all the data in my IT infrastructure."
"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

"The setup is difficult so could be easier."
"In terms of probability, every now and then there are changes coming and going."
"The pricing could be better, and it could have an easier implementation."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"The licensing model could be improved."
"We would prefer to be able to manage the solution on the cloud."
"While this solution is cost-effective, in general, the price could be better."
"The tool should improve its multi-cloud feature."
"They should enhance its online meeting features."
"Zimbra is not very stable, but it's okay."
"There are some bugs we found that could be fixed."
"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 security and performance issues which is one of the concerns of using an open-source product."
"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."
"We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming."
 

Pricing and Cost Advice

"We pay for the license annually."
"The pricing is expensive."
"I rate Microsoft Exchange's pricing a six out of ten."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Its price is fair."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The price of the solution is low."
"The solution is competitively priced."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"We do not pay for licenses to use this solution."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The solution is not expensive compared to other products."
