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

"On-premises Microsoft Exchange is good because it protects data privacy."
"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."
"It gives me benefit in terms of integration with other services such as SharePoint, Microsoft Teams, and OneDrive, and it makes my work much easier."
"The exchange functionalities are good."
"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"Microsoft Exchange is a user-friendly product that is easy to manage and configure."
"It is easy to use and we can allow many users because now our users are scattered, they cover a wide area, and we can use it from anywhere, which is the main benefit for us."
"With the cloud coming in, scalability is not an issue even for Microsoft."
"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."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"The web interface is powerful and easy to use."
"The Zimbra Collaboration's most valuable feature is web access."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"Good email solution and it's open-source."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"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

"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"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."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"The licensing model could be improved."
"For new users, it might take them some time to get used to the product."
"The solution could improve by making it easier to use."
"Zimbra is not very stable, but it's okay."
"We have had an issue with security."
"There are security and performance issues which is one of the concerns of using an open-source product."
"The antispam and antivirus features are hard to understand on mobile devices."
"It would be great if a group chat feature were created to allow for a team environment."
"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."
"The product must be more customizable."

"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"The price of the solution is low."
"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.
