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 easy to use and we can allow many users because now our users are scattered, they cover a wide area, and we can use it from anywhere, which is the main benefit for us."
"Technical support is good."
"The email management system is very easy to set up, configure, and use."
"Exchange is very scalable, it's one of the most important things about this software."
"Now, we manage to serve almost 99% of the information."
"Exchange has helped us with encryption."
"On-premises Microsoft Exchange is good because it protects data privacy."
"Microsoft Exchange is a powerful solution, it can easily integrate with Active Directory and other business applications, it does not require any training, it is flexible and simple to use, and when comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."
"The web interface is powerful and easy to use."
"For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy."
"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."
"The stability is good and keeps getting better with each new update."
"The backup and storage management features of Zimbra Collaboration are valuable."
"The pricing of the solution is excellent; it's a newer solution with a modern interface and dashboard, the interface itself is very responsive and easy to navigate, the initial setup is very simple and straightforward, the stability is good and keeps getting better with each new update, and the solution really does scale very easily."
"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."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
 

Cons

"While this solution is cost-effective, in general, the price could be better."
"For the next release, there are some features on the cloud-based Exchange that aren't included on-prem. It would be great if these features were made available in the next release. For instance, integration between Exchange and its on-prem calendar is not available for the on-prem solution."
"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Research and Development."
"The solution should be easier to deploy."
"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."
"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."
"Its search functionality can be better. It is currently not really easy."
"It would be great if a group chat feature were created to allow for a team environment."
"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."
"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."
"File sharing permissions with Nextcloud integration need improvement."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"It does have a few bugs."
"I would like to see a Microsoft schedule function added."
"Zimbra is not very stable, but it's okay."
 

Pricing and Cost Advice

"This solution is expensive."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"The solution's pricing is fine...I do think the tool offers value for money."
"Microsoft Exchange is an inexpensive application."
"Microsoft Exchange itself does not require a license, but users who will have mailboxes will require a license. It depends on the number of users to choose which license. If you exceed 2,000 mailboxes, it's preferable to get the enterprise license."
"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."
"I don't have enough information about the licensing costs of Microsoft Exchange, but I do know that you need two types of licenses to run it. You need the product key and the client access key to activate Microsoft Exchange. This means that apart from the standard Microsoft Exchange licensing fees, you have to pay additional costs."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We pay yearly licenses for Zimbra Collaboration."
"The solution is not expensive compared to other products."
"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."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The solution is competitively priced."
