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.

"This is a good email solution and it's open-source which is great and the most important feature for us."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"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."
"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."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."
 

Cons

"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."
"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. In fact, many of the files we had moved to the cloud had disappeared. There also seems to be a problem with the retention of information."
"The price of Microsoft Exchange could improve, it is priced high."
"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"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 can be a little finicky, sometimes, or flakey."
"An area for improvement would be the convenience of working with Azure services from Exchange on-premise installations."
"Microsoft could make it easier to combine comments in the GUI. It isn't easy to do certain things in Exchange, primarily if the administrator isn't used to the command line, so I think the customer interface could be improved."
"There are some bugs we found that could be fixed."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
"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."
"I would like to see a Microsoft schedule function added."
"Zimbra is not very stable, but it's okay."
"Zimbra Collaboration's video conferencing could be improved."
"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."
"It does have a few bugs."
 

Pricing and Cost Advice

"The product pricing is reasonable if you utilize its full suite of features."
"It would be nice if it used less resources to run on-premise."
"I rate Microsoft Exchange's pricing a six out of ten."
"The product is quite cheap."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"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."
"The solution's pricing is fine...I do think the tool offers value for money."
"The price of the solution is low."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"Zimbra Collaboration offers a good price-to-feature ratio."
"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."
