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's pretty easy to manage."
"The most used feature of Microsoft Exchange is the email capability, especially since it integrates with the calendar."
"Exchange is very scalable, it's one of the most important things about this software."
"The product can scale."
"The product works very well."
"I find the Outlook client very valuable. It allows me to connect to the Exchange Server and send and receive emails easily. The graphical interface is user-friendly and has a good look and feel."
"I find the desktop version of Microsoft Exchange looks better than the online version. You can make it a white background. You might be able to make the online background white, but I have no idea how to do that. I know how to do it only on the desktop version"
"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."
"The web interface is powerful and easy to use."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"Zimbra Collaboration has a good web interface."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The configuration is simple."
"The most valuable feature of Zimbra Collaboration is the cost."
"Network NG Modules are valuable to us."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
 

Cons

"I'd like the archiving process to be faster."
"In our current situation, the disappearance of sanctions would be a tangible improvement. We are basically cut off from technical support and it's very difficult to obtain any updates."
"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."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"I think it could be more scalable."
"Microsoft Exchange and other Microsoft solutions like Office 365 need to provide more detailed information for customers regarding the features and functionalities included in their plans, as some features are only available at an additional cost."
"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."
"The biggest issue with Microsoft Exchange is its high cost, especially in pricing for license upgrades and expansion to more users."
"The tool should improve its multi-cloud feature."
"The installation is not straightforward, it can take two days for the full implementation."
"There are some security issues."
"We have had an issue with security."
"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 solution could improve by making it easier to use."
"The antispam and antivirus features are hard to understand on mobile devices."
"The product must be more customizable."
 

Pricing and Cost Advice

"It would be nice if it used less resources to run on-premise."
"Its price is okay."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"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."
"It's a little bit expensive."
"Licensing fees are paid monthly."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"Microsoft Exchange itself does not require a license, but users who will have mailboxes will require a license. It depends on the number of users to choose which license. If you exceed 2,000 mailboxes, it's preferable to get the enterprise license."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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."
"Zimbra Collaboration offers a good price-to-feature ratio."
"The solution is not expensive compared to other products."
"We do not pay for licenses to use this solution."
"We pay yearly licenses for Zimbra Collaboration."
"The price of the solution is low."
