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.

Pros

"It is a product that is simple to manage, and easy to use."
"The integration of Microsoft Exchange with other tools allows for seamless collaboration and increased productivity within teams."
"It's user-friendly."
"It is easy to set up."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"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."
"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 product is easy to set up."
"The most valuable feature of Zimbra Collaboration is the cost."
"Zimbra Collaboration's sharing features are most valuable."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The backup and storage management features of Zimbra Collaboration are valuable."
 

Cons

"One thing for improvement would be to have an offline version of Exchange available for use if our connection goes down."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"I think it could be more scalable."
"The security features could be improved. There should be a better policy management system."
"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"I would like to see the search capability of the Outlook client improved"
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"I'd like the archiving process to be faster."
"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."
"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."
"We have had an issue with security."
"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 solution could improve by making it easier to use."
"The installation is not straightforward, it can take two days for the full implementation."

Pricing and Cost Advice

"Its price is fair."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The price of Microsoft Exchange is reasonable."
"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."
"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."
"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."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"Zimbra Collaboration offers a good price-to-feature ratio."
"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."
"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."
