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

"Customers can benefit from this new pricing model because it's expensive and now with the subscription they can budget for this."
"Exchange has helped us with encryption."
"It's pretty easy to manage."
"Microsoft has a very good support team."
"On-premises Microsoft Exchange is good because it protects data privacy."
"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."
"Microsoft Exchange is comparable to the Outlook client. Both are Microsoft products, and most people are familiar with Outlook. This is why the best feature of Microsoft Exchange is the ease of use. It is more compatible with the client software, especially for Microsoft Outlook. There are a lot of features available that are required for businesses users."
"Overall, I am satisfied with the product."
"The web interface is powerful and easy to use."
"Zimbra Collaboration has a good web interface."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"Network NG Modules are valuable to us."
"The most valuable feature of Zimbra Collaboration is email functionality."
"We can control all the data in my IT infrastructure."
"The stability is good and keeps getting better with each new update."
"The backup and storage management features of Zimbra Collaboration are valuable."
 

Cons

"They could improve on the search function, it takes too much time."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"Microsoft Exchange could improve by adding artificial intelligence."
"The solution could be more secure."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"Deployment should become a bit easier, the process is a bit complicated. There are a lot of complications compared to Gmail For Business, which is a bit easier when it comes to configuration."
"In our current situation, the disappearance of sanctions would be a tangible improvement. We are basically cut off from technical support and it's very difficult to obtain any updates."
"If it was the same product, and slightly cheaper, that would be amazing."
"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"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."
"They should enhance its online meeting features."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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."
"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."
"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."
 

Pricing and Cost Advice

"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."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"It is not expensive."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"The price of Microsoft Exchange is reasonable."
"We pay yearly licenses for Zimbra Collaboration."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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."
"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 solution is competitively priced."
"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."
