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 availability group settings are better, so it has inherent scalability. In 2010, they added several sensible rules."
"It is a very stable tool...It is a very scalable tool."
"Microsoft Exchange is comparable to the Outlook client, both are Microsoft products, and most people are familiar with Outlook, which is why the best feature of Microsoft Exchange is the ease of use, as it is more compatible with the client software, especially for Microsoft Outlook, and there are a lot of features available that are required for business users."
"We've been using Exchange as an email platform; our clients require multi-country, multi-regional email collaboration with controlled mail flow, and the most valuable feature is the capability of message tracking and the protection of user data."
"In general, this is a good product and I am happy with it."
"The best features are that Exchange is very customer-friendly, its interface is self-explanatory, it doesn't hang, and it keeps evolving."
"For me, it's always worked quite well, and because of that, I haven't given anything about it much thought."
"Exchange is very scalable, it's one of the most important things about this software."
"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 most valuable feature of Zimbra Collaboration is the cost."
"The product is easy to set up."
"The Zimbra Collaboration's most valuable feature is web access."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"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."
 

Cons

"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"Exchange's management could be improved a bit, and its troubleshooting tools are limited at times."
"It's not always the finest solution in terms of integration with products that are not from Microsoft. It integrates very well with Microsoft products but not with third-party products."
"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."
"I think it could be more scalable."
"One thing for improvement would be to have an offline version of Exchange available for use if our connection goes down."
"They keep making all these changes, and our system was down for four or five days. They finally got it up, but there are still lots of quirks."
"In terms of probability, every now and then there are changes coming and going. The changes are not that frequent because every month they got updates back, so that is an issue."
"Zimbra is not very stable, but it's okay."
"It would be great if a group chat feature were created to allow for a team environment."
"The product must be more customizable."
"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 antispam and antivirus features are hard to understand on mobile devices."
"It does have a few bugs. However, they are small and can be worked around."
"The solution could improve by making it easier to use."
"The installation is not straightforward, it can take two days for the full implementation."
 

Pricing and Cost Advice

"The platform has a reasonable price."
"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."
"It would be nice if it used less resources to run on-premise."
"I rate Microsoft Exchange's pricing a six out of ten."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Microsoft Exchange is a very well-priced solution."
"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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"We pay yearly licenses for Zimbra Collaboration."
"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 not expensive compared to other products."
"Zimbra Collaboration offers a good price-to-feature ratio."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
