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

"Exchange is a robust system that is well suited for an enterprise environment. It's always up, and we hardly face any technical issues. Exchange has a web interface and integrates perfectly with Microsoft Outlook. This web interface can be easily used to change the passwords from the domain controllers."
"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 Exchange is a user-friendly product that is easy to manage and configure."
"It's a very user-friendly application. The mail server is also valuable when compared to other services like SquirrelMail."
"Exchange has helped us with encryption."
"I find Exchange's basic mail features to be highly valuable."
"The most valuable feature of Microsoft Exchange is its ease of use."
"With the cloud coming in, scalability is not an issue even for Microsoft."
"The solution is easy to implement."
"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."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The backup and storage management features of Zimbra Collaboration are valuable."
"The product is easy to set up."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"The configuration is simple."
 

Cons

"There is a problem when scheduling an event for the whole day."
"I would like to see Microsoft Exchange improve their documentation."
"The licensing model could be improved."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"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."
"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."
"In terms of what should be improved, they should probably move to a cloud option like Office 365. We would like to get this functionality without the need to deploy complex hardware and software solutions. This should be the next thing, making Exchange more related to Office products, which are more cloud-oriented, less on-premise or desktop-oriented solutions, like the direction Google is strongly moving towards."
"There can be occasional challenges during the product's implementation phase, making it an area where improvements are needed."
"The installation is not straightforward, it can take two days for the full implementation."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"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."
"Zimbra Collaboration's video conferencing could be improved."
"The solution could use more integration with third-party tools."
"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."
"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."
"File sharing permissions with Nextcloud integration need improvement."
 

Pricing and Cost Advice

"The product pricing is reasonable if you utilize its full suite of features."
"Microsoft Exchange is a very well-priced solution."
"This solution is expensive."
"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."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"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."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"The solution is not expensive compared to other products."
"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 do not pay for licenses to use this solution."
"The price of the solution is low."
"Zimbra Collaboration offers a good price-to-feature ratio."
"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."
"We pay yearly licenses for Zimbra Collaboration."
