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 user friendly."
"It is stable."
"It gives me benefit in terms of integration with other services such as SharePoint, Microsoft Teams, and OneDrive. It makes my work much easier."
"What I love about Microsoft Exchange is the good integration since 2013, particularly its integration with the calendar and other software such as Zoom, TeamViewer, AnyDesk, etc."
"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."
"Support is very good."
"Customers can benefit from this new pricing model because it's expensive and now with the subscription they can budget for this."
"Scalability-wise, I rate the solution a ten out of ten."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The stability is good and keeps getting better with each new update."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The solution is easy to implement."
"Good email solution and it's open-source."
"We can control all the data in my IT infrastructure."
"The most valuable feature of Zimbra Collaboration is the cost."
"The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
 

Cons

"From a security perspective, Microsft Exchange can be improved. All that needs to be added is security, but that's an internal hierarchical problem from the product itself and not the end-users."
"Microsoft Exchange's customer support could be faster and more knowledgeable."
"If it was the same product, and slightly cheaper, that would be amazing."
"Exchange can be a little finicky, sometimes, or flakey. Last week, for example, I had gone into my calendar to check on some briefings that I had established, and then went back into my inbox, and suddenly the view had changed. I had no idea what it was that I had done, and I couldn't figure out how to get that view back. I took a productivity hit as a result of that, trying to fix it, due to the fact that it just wasn't what I wanted. It wasn't what I was used to working with. Two different tech support people had to work with me in order to get the view back to what I wanted just so I could be productive."
"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"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."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"It would be great if a group chat feature were created to allow for a team environment."
"File sharing permissions with Nextcloud integration need improvement."
"The antispam and antivirus features are hard to understand on mobile devices."
"The product must be more customizable."
"I would like to see a Microsoft schedule function added."
"The tool should improve its multi-cloud feature."
"The solution could improve by making it easier to use."
"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."
"The solution's pricing is fine...I do think the tool offers value for money."
"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."
"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."
"Microsoft Exchange is an inexpensive application."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Its price is fair."
"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."
"The price of the solution is low."
"Zimbra Collaboration offers a good price-to-feature ratio."
"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."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The solution is competitively priced."
