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 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."
"The most beneficial aspects of Microsoft Exchange are that it is solid, dependable, and 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."
"Microsoft has a very good support team."
"It is a product that is simple to manage, and easy to use."
"The availability group settings are better, so it has inherent scalability. In 2010, they added several sensible rules."
"It integrates well with calendar, scheduling, etc. It's easy for employees to make meetings and plan their agendas."
"The initial setup is quite a straightforward process. I don't think it is a very complicated solution. Plenty of things could be more complex, but the ordinary, general settings are quite simple."
"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."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"Zimbra Collaboration's sharing features are most valuable."
"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."
"Zimbra Collaboration has a good web interface."
"The most valuable feature of Zimbra Collaboration is the cost."
"The backup and storage management features of Zimbra Collaboration are valuable."
"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

"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."
"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 platform could be more user-friendly."
"The main problem with Microsoft products is that we're constantly required to install patches and fixes."
"Microsoft could make it easier to combine comments in the GUI. It isn't easy to do certain things in Exchange, primarily if the administrator isn't used to the command line, so I think the customer interface could be improved."
"One major area for improvement is the need for repeated authentication when running a meeting."
"The solution could be more secure."
"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."
"There are some security issues."
"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 solution’s forums don't have much information or documentation on administration tasks."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"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."
"The product must be more customizable."
"The installation is not straightforward, it can take two days for the full implementation."
"It does have a few bugs."
 

Pricing and Cost Advice

"The product pricing is reasonable if you utilize its full suite of features."
"Licensing fees are paid monthly."
"Microsoft Exchange is an inexpensive application."
"We pay for the license annually."
"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 rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"It's working very well. There is no problem, but the price is not the best."
"Zimbra Collaboration offers a good price-to-feature ratio."
"The price of the solution is low."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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 competitively priced."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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."
