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

"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"Customers can benefit from this new pricing model because it's expensive and now with the subscription they can budget for this."
"It gives me benefit in terms of integration with other services such as SharePoint, Microsoft Teams, and OneDrive. It makes my work much easier."
"It's so much of a part of what I do every day that I don't give it a lot of thought. It just works, for the most part, until it doesn't, in which case I call tech support."
"Exchange's interface is good. All of our engineers like it and are accustomed to using it."
"The backup and archiving features are valuable, it is user friendly too."
"The availability group settings are better, so it has inherent scalability. In 2010, they added several sensible rules."
"It is a product that is simple to manage, and easy to use."
"Good email solution and it's open-source."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"Zimbra Collaboration's sharing features are most valuable."
"The most valuable feature of Zimbra Collaboration is the cost."
"The backup and storage management features of Zimbra Collaboration are valuable."
"The Zimbra Collaboration's most valuable feature is web access."
"The solution is easy to implement."
"Network NG Modules are valuable to us."
 

Cons

"Load balancing is lacking."
"If it was the same product, and slightly cheaper, that would be amazing."
"The price of Microsoft Exchange could improve, it is priced high."
"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."
"The solution's hybrid deployment process could be improved, particularly for customers who initially started in the cloud and may want to return to an on-premises setup. Microsoft could make this transition more flexible."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"I do not have any notes for improvement."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"The product must be more customizable."
"I would like to see a Microsoft schedule function added."
"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."
"We have had an issue with security."
"The solution could improve by making it easier to use."
"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."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"The solution’s forums don't have much information or documentation on administration tasks."
 

Pricing and Cost Advice

"Its price is okay."
"Its price is fair."
"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."
"It's a little bit expensive."
"The pricing is expensive."
"It is not expensive."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"The product pricing is reasonable if you utilize its full suite of features."
"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."
"The solution is competitively priced."
"We do not pay for licenses to use this solution."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
