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 exchange functionalities are good."
"Microsoft provides you with an ease of control and management and sets certain expectations from the software that you can't have if you implement other, cheaper solutions that are likely to be more difficult to manage or that are unable to adapt to new demands."
"All features are useful; they meet the purpose of an email server."
"Microsoft Exchange is highly stable for the end-user systems."
"We have found it to be a stable solution. It is scalable and easy to install."
"Our customers are satisfied with the features included in Microsoft Exchange."
"The deployment is a plug-and-play process."
"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."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The stability is good and keeps getting better with each new update."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy."
"Network NG Modules are valuable to us."
"Zimbra Collaboration has a good web interface."
 

Cons

"Microsoft Exchange could improve security. They can elevate a lot of security features."
"The support needs to be more knowledgeable."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"It is overall all good, though technical support is just average."
"The tool is not easy to use. Every person has to have at least administration-level experience to use the tool."
"One thing for improvement would be to have an offline version of Exchange available for use if our connection goes down."
"The filtering of spam needs significant improvement, as many spam emails are not getting detected."
"There can be difficulties resolving problems on the server side when problems arise."
"There are some bugs we found that could be fixed."
"There are some security issues."
"It would be great if a group chat feature were created to allow for a team environment."
"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."
"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."
"Zimbra Collaboration's video conferencing could be improved."
"File sharing permissions with Nextcloud integration need improvement."
 

Pricing and Cost Advice

"The pricing is expensive."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"I have Outlook 365 Professional, and Exchange comes in the bundle with other solutions, such as Word and OneDrive. I pay for the use of the bundle monthly and I can imagine if you are a company with many licenses the pricing model would be a lot different."
"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."
"This solution is expensive."
"It would be nice if it used less resources to run on-premise."
"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."
"I rate Microsoft Exchange's pricing a six out of ten."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The solution is not expensive compared to other products."
"The price of the solution is low."
"We do not pay for licenses to use this solution."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"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."
