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

"Exchange's interface is good. All of our engineers like it and are accustomed to using it."
"It ensures high availability and resilience, allowing seamless recovery from potential failures and making it a reliable option for business-critical operations."
"The solution can scale up to whatever number of users one desires."
"Now, we manage to serve almost 99% of the information."
"Exchange is very scalable, it's one of the most important things about this software."
"All of Exchange's features are valuable; for example, we can configure the MAPI profile, IM profile, or mobile profile."
"The initial setup is quite a straightforward process; I don't think it is a very complicated solution, as plenty of things could be more complex, but the ordinary, general settings are quite simple."
"Microsoft Exchange is a very well-priced solution."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"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."
"Network NG Modules are valuable to us."
"It is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The web interface is powerful and easy to use."
"The solution is easy to implement."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
 

Cons

"They could offer simultaneous features for Exchange Online and on-premises versions. Specific features such as litigation hold and audit setups should be available on-premises."
"It is overall all good, though technical support is just average."
"Microsoft Exchange could improve by adding artificial intelligence."
"The desktop version of Microsoft Exchange receives emails a little slower than the online version."
"Microsoft could improve on Exchange's hybrid deployment or HCW. They need to improve on that because I was having many issues with HCW in our environment at times."
"I'd like the archiving process to be faster."
"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."
"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."
"I would like to see a Microsoft schedule function added."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"Zimbra is not very stable, but it's okay."
"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."
"There are some bugs we found that could be fixed."
"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."
"We have had an issue with security."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
 

Pricing and Cost Advice

"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."
"It would be nice if it used less resources to run on-premise."
"This solution is expensive."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Its price is okay."
"The product pricing is reasonable if you utilize its full suite of features."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"The solution's pricing is fine...I do think the tool offers value for money."
"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."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"We do not pay for licenses to use this solution."
"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."
"The price of the solution is low."
"We pay yearly licenses for Zimbra Collaboration."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
