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:

"In general, this is a good product and I am happy with it."
"Microsoft Exchange is a very well-priced solution."
"Our customers are satisfied with the features included in Microsoft Exchange."

"Microsoft support is very good."
"It integrates well with calendar, scheduling, etc. It's easy for employees to make meetings and plan their agendas."
"The flexibility that Microsoft has to offer, especially when it comes to email, is better."
"The stability is good and keeps getting better with each new update."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"The web interface is powerful and easy to use."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"The web interface is powerful and easy to use."
"The most valuable feature of Zimbra Collaboration is email functionality."
"Zimbra Collaboration has a good web interface."
"The Zimbra Collaboration's most valuable feature is web access."
 

Cons

"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."
"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."
"The desktop version of Microsoft Exchange receives emails a little slower than the online version."
"For new users, it might take them some time to get used to the product."
"They could offer simultaneous features for Exchange Online and on-premises versions. Specific features such as litigation hold and audit setups should be available on-premises."
"I think it could be more scalable."
"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."
"The solution should be easier to deploy."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The installation is not straightforward, it can take two days for the full implementation."
"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 product must be more customizable."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."
"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 solution could improve by making it easier to use."
 

Pricing and Cost Advice

"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"The product pricing is reasonable if you utilize its full suite of features."
"Its price is okay."
"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."
"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."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."
"I don't have enough information about the licensing costs of Microsoft Exchange, but I do know that you need two types of licenses to run it. You need the product key and the client access key to activate Microsoft Exchange. This means that apart from the standard Microsoft Exchange licensing fees, you have to pay additional costs."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
"The solution is competitively priced."
"We do not pay for licenses to use this solution."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"The price of the solution is low."
