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

"Internal communication stability within Exchange is ensured by the stability of the internal network which is guaranteed by default."
"The most used feature of Microsoft Exchange is the email capability, especially since it integrates with the calendar."
"It is very well integrated with other Microsoft programs, teams, and so on. They work well together."
"I find Exchange's basic mail features to be highly valuable."
"Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."
"With the cloud coming in, scalability is not an issue even for Microsoft."
"The technical support services are good."
"It's so much of a part of what I do every day that I don't give it a lot of thought. It just works, for the most part, until it doesn't, in which case I call tech support."
"Zimbra Collaboration has a good web interface."
"We can control all the data in my IT infrastructure."
"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."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."
"Network NG Modules are valuable to us."
"Good email solution and it's open-source."
 

Cons

"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"Microsoft Exchange could improve by adding artificial intelligence."
"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."
"Microsoft Exchange could improve the price."
"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."
"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."
"Microsoft Exchange could improve by being more secure. We are always looking to have more security."
"The management of .pst files and archiving need improvement."
"It would be great if a group chat feature were created to allow for a team environment."
"The installation is not straightforward, it can take two days for the full implementation."
"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 should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"It does have a few bugs."
"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."
"We have had an issue with security."
 

Pricing and Cost Advice

"It's a little bit expensive."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"It would be nice if it used less resources to run on-premise."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"The solution's pricing is fine...I do think the tool offers value for money."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"We pay for the license annually."
"It's working very well. There is no problem, but the price is not the best."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"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."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"We do not pay for licenses to use this solution."
"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 pay yearly licenses for Zimbra Collaboration."
