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 is a product that is simple to manage, and easy to use."
"All of Exchange's features are valuable. For example, we can configure the MAPI profile, IM profile, or mobile profile."
"I find Exchange's basic mail features to be highly valuable."
"The most valuable feature of Microsoft Exchange is its ease of use."
"It integrates well with other tools."
"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"The integration of Microsoft Exchange with other tools allows for seamless collaboration and increased productivity within teams."
"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 most valuable feature of Zimbra Collaboration is the cost."
"Good email solution and it's open-source."
"We can control all the data in my IT infrastructure."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"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 Zimbra Collaboration's most valuable feature is web access."
 

Cons

"For the next release, there are some features on the cloud-based Exchange that aren't included on-prem. It would be great if these features were made available in the next release. For instance, integration between Exchange and its on-prem calendar is not available for the on-prem solution."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"The tool is not easy to use. Every person has to have at least administration-level experience to use the tool."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"The cost could be cheaper."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"In terms of probability, every now and then there are changes coming and going. The changes are not that frequent because every month they got updates back, so that is an issue."
"Microsoft Exchange could improve by adding artificial intelligence."
"The solution could use more integration with third-party tools."
"The installation is not straightforward, it can take two days for the full implementation."
"I would like to see a Microsoft schedule function added."
"The product must be more customizable."
"It would be great if a group chat feature were created to allow for a team environment."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The tool should improve its multi-cloud feature."
"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."
 

Pricing and Cost Advice

"The pricing is expensive."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"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."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"The product is quite cheap."
"It's working very well. There is no problem, but the price is not the best."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The solution is not expensive compared to other products."
"We pay yearly licenses for Zimbra Collaboration."
"The price of the solution is low."
"We do not pay for licenses to use this solution."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
