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's very well integrated with OneDrive and Teams Calendar."
"The most valuable feature of Microsoft Exchange is the collaboration tools."
"One of the most valuable features of Microsoft Exchange is its security."
"All features are useful; they meet the purpose of an email server."
"We have found it to be a stable solution. It is scalable and easy to install."
"Exchange is easy to use. It also has a built-in calendar for all the stuff I'm supposed to be looking at and doing. Exchange tells you if you have a doctor's appointment or a scheduled call. It also has a place to store and manage your contacts. If I want to add a new contact, it will put in information about that contact stored anywhere within the Microsoft Suite."
"The best features are that Exchange is very customer-friendly, its interface is self-explanatory, it doesn't hang, and it keeps evolving."
"It integrates well with other tools."
"The solution is easy to implement."
"Network NG Modules are valuable to us."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"Good email solution and it's open-source."
"The stability is good and keeps getting better with each new update."
 

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."
"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."
"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."
"There are issues when you add your domain to Microsoft Tenant, and you try to create that. Which is a problem for me."
"The setup is difficult so could be easier."
"If it was the same product, and slightly cheaper, that would be amazing."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"Microsoft Exchange needs to improve how it handles and assigns policy and security."
"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."
"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."
"File sharing permissions with Nextcloud integration need improvement."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"I would like to see a Microsoft schedule function added."
"There are some security issues."
"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."
"The installation is not straightforward, it can take two days for the full implementation."
 

Pricing and Cost Advice

"Microsoft Exchange is a very well-priced solution."
"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."
"We pay for the license annually."
"Microsoft Exchange is an inexpensive application."
"We are currently using enterprise licenses for the solution. They are different pricing models available. There are individual, cloud-based, and enterprise licenses all with different pricing models. The larger the number of users, the lesser the price. For small to medium companies like us, we feel it is expensive."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"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."
"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"
"We pay yearly licenses for Zimbra Collaboration."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The price of the solution is low."
"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."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
