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

"One of the most valuable features of Microsoft Exchange is its security."
"It has a feature that allows you to retain an email and recover it as an administrator. When you activate this feature, even if a user deletes an email, the email is still in the system, and we can retrieve it as an administrator. It is a very useful function. We turn this feature on for some of the mailboxes because we need to keep all the records. I like the way emails are classified in this solution. It makes it really easy to take a look at the most important messages. This is a really good functionality. Some of the emails directly exchanged with you are marked as important and shown in one tab, and everything else is in another tab. We usually don't have any issue with Exchange. It can be integrated with different solutions."
"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, tells you if you have a doctor's appointment or a scheduled call, and has a place to store and manage your contacts, automatically filling in information about a new contact stored anywhere within the Microsoft Suite."
"Exchange is very scalable, it's one of the most important things about this software."
"It's a very user-friendly application. The mail server is also valuable when compared to other services like SquirrelMail."
"The best features are that Exchange is very customer-friendly, its interface is self-explanatory, it doesn't hang, and it keeps evolving."
"On-premises Microsoft Exchange is good because it protects data privacy."
"It's very well integrated with OneDrive and Teams Calendar."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"Despite sticking with Gmail for over a decade in terms of business, Zimbra have impressed me with some other aspects as well; if the time comes, I would prefer Zimbra to my current solution."
"Good email solution and it's open-source."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"The most valuable feature of Zimbra Collaboration is the cost."
"The web interface is powerful and easy to use."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
 

Cons

"More AI features would be good."
"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."
"For new users, it might take them some time to get used to the product."
"It is overall all good, though technical support is just average."
"The calendar integration in Exchange is not that great. The email features are okay, but it doesn't integrate well with the calendar and appointments, especially Zoom appointments. It integrates fine with Microsoft Teams, but Zoom is a challenge."
"The setup is difficult so could be easier."
"They could improve on the search function, it takes too much time."
"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 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."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
"Zimbra is not very stable, but it's okay."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"The antispam and antivirus features are hard to understand on mobile devices."
"File sharing permissions with Nextcloud integration need improvement."
"The solution’s forums don't have much information or documentation on administration tasks."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."
 

Pricing and Cost Advice

"Its price is okay."
"The product pricing is reasonable if you utilize its full suite of features."
"Microsoft Exchange is a very well-priced solution."
"The product is quite cheap."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"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."
"The price of Microsoft Exchange is reasonable."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"We do not pay for licenses to use this solution."
"The solution is not expensive compared to other products."
"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."
"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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
