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

"Exchange's best feature is single sign-on access using the Microsoft Identity framework."
"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."
"Exchange's interface is good. All of our engineers like it and are accustomed to using it."
"The functionality on the user side is quite good. Exchange provides an excellent platform for collaboration between users."
"Microsoft has a very good support team."
"It integrates well with other tools."
"It's pretty easy to manage."
"Exchange is very scalable, it's one of the most important things about this software."
"Zimbra Collaboration has a good web interface."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"The stability is good and keeps getting better with each new update."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"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 most valuable feature of Zimbra Collaboration is email functionality."
"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."
 

Cons

"The platform could be more user-friendly."
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"The setup is difficult so could be easier."
"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."
"The price of Microsoft Exchange could improve, it is priced high."
"I'd like the archiving process to be faster."
"If it was the same product, and slightly cheaper, that would be amazing."
"Microsoft Exchange needs to improve how it handles and assigns policy and security."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"I would like to see a Microsoft schedule function added."
"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 installation is not straightforward, it can take two days for the full implementation."
"The solution could improve by making it easier to use."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The solution’s forums don't have much information or documentation on administration tasks."
"The solution could use more integration with third-party tools."
 

Pricing and Cost Advice

"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."
"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."
"Microsoft Exchange is a very well-priced solution."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"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."
"Its price is fair."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"We pay yearly licenses for Zimbra Collaboration."
