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

"Customers can benefit from this new pricing model because it's expensive and now with the subscription they can budget for this."
"I find Exchange's basic mail features to be highly valuable."
"It's an excellent product from Microsoft. It provides more flexibility to the end-users. As it's connected with Teams, it also enables collaboration."
"Exchange is a robust system that is well suited for an enterprise environment. It's always up, and we hardly face any technical issues. Exchange has a web interface and integrates perfectly with Microsoft Outlook. This web interface can be easily used to change the passwords from the domain controllers."
"The most valuable feature of Microsoft Exchange is the collaboration tools."
"The initial setup is very simple."
"Microsoft Exchange is highly stable for the end-user systems. When we move to Office 365, it will be even more stable even. There's less administration required and it's very robust. We are really quite happy in using that."
"The email management system is very easy to set up, configure, and use."
"Zimbra Collaboration has a good web interface."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
"The backup and storage management features of Zimbra Collaboration are valuable."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The most valuable feature of Zimbra Collaboration is the cost."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The configuration is simple."
"The web interface is powerful and easy to use."
 

Cons

"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
"They could continue to improve the consolidation and integration of mailbox services to make them more flexible, easier to deploy, and more manageable."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"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."
"I do not have any notes for improvement."
"Microsoft Exchange could improve by adding artificial intelligence."
"Zimbra Collaboration's video conferencing could be improved."
"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."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."
"The product must be more customizable."
"There are some security issues."
"The solution could improve by making it easier to use."
"The installation is not straightforward, it can take two days for the full implementation."
"The tool should improve its multi-cloud feature."
 

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."
"It's a little bit expensive."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Microsoft Exchange is a very well-priced solution."
"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."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"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."
"Zimbra Collaboration offers a good price-to-feature ratio."
"We do not pay for licenses to use this solution."
"The solution is competitively priced."
"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."
"The solution is not expensive compared to other products."
"We pay yearly licenses for Zimbra Collaboration."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
