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 email management system is very easy to set up, configure, and use."
"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."
"Exchange is an ever growing environment that will always have stronghold in the world of communicating and organizing information that is reliable."
"It is easy to use and we can allow many users because now our users are scattered They over a wide area. We can use it from anywhere. That is the main benefit for us."
"All features are useful; they meet the purpose of an email server."
"This solution handles all of our primary functionality including email, message delivery, message archiving and calendars."
"The solution can scale well."
"The search tools are good."
"The web interface is powerful and easy to use."
"Zimbra Collaboration has a good web interface."
"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."
"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 solution is easy to implement."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"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."
 

Cons

"Its stability is not so great. We can't move mailboxes because of a corrupt file or random issues, which causes headaches."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"It is important to have the updated version for scalability."
"It doesn't work very well on a virtual machine. We had to move it around. There are also issues when you try to move it between computers."
"We are not able to use Microsoft Teams due to connection issues. Thus, the product integration with Teams could be improved."
"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."
"When we started using Exchange on the cloud, we had a lot of initial problems relating to our main database and we also experienced issues with the accidental deletion of inboxes, amongst other things. In fact, many of the files we had moved to the cloud had disappeared. There also seems to be a problem with the retention of information."
"I think it could be more scalable."
"I would like to see a Microsoft schedule function added."
"The product must be more customizable."
"File sharing permissions with Nextcloud integration need improvement."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The support was lacking in my experience."
"It does have a few bugs."
"Zimbra Collaboration's video conferencing could be improved."
"The solution could improve by making it easier to use."
 

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."
"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"It is not expensive."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The pricing is expensive."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"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."
"The product pricing is reasonable if you utilize its full suite of features."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"We pay yearly licenses for Zimbra Collaboration."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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 competitively priced."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
