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

"Using EWS support, we have created a custom UI to display meeting info on our local portal to utilize and manage meeting and conference rooms effectively."
"It is a product that is simple to manage, and easy to use."
"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."
"Our customers are satisfied with the features included in Microsoft Exchange."
"It's pretty easy to manage."

Cons

"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources. Configuration needs to be much more streamlined and administratively automated."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"It is important to have the updated version for scalability."
"In terms of probability, every now and then there are changes coming and going."

"I would like to see a Microsoft schedule function added."

"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"The product must be more customizable."

"Zimbra is not very stable, but it's okay."
 

Pricing and Cost Advice

"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Microsoft Exchange is a very well-priced solution."
"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."
"The product pricing is reasonable if you utilize its full suite of features."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"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 do not pay for licenses to use this solution."
"The solution is competitively priced."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"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."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
