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 is enterprise-friendly, and many organizations use it."
"It's very well integrated with OneDrive and Teams Calendar."
"The most valuable features of Microsoft Exchange are it is always online and has broad email and file-sharing capabilities."
"Microsoft Exchange's most valuable feature is that it's old-fashioned communication, meaning it's good for people who aren't able to work comfortably in a cloud environment."
"Microsoft support is very good."
"The setup program is straightforward, but there are hiccups when you try to move it between computers."
"It's an excellent product from Microsoft. It provides more flexibility to the end-users. As it's connected with Teams, it also enables collaboration."
"For me, it's always worked quite well, and because of that, I haven't given anything about it much thought."
"Zimbra Collaboration has a good web interface."
"The backup and storage management features of Zimbra Collaboration are valuable."
"For an SMB, it is a recommendable email solution."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"The product is easy to set up."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
"The most valuable feature of Zimbra Collaboration is the cost."
"The configuration is simple."
 

Cons

"The licensing could be better."
"The platform could be more user-friendly."
"I see some drawbacks and areas for improvement; the quarantining is not fantastic because it lets a lot of spam through, and when it is notified of spam, it does not particularly alter its behavior quickly."
"The security for the email technology could be improved."
"Microsoft Exchange could improve the archiving of emails and the performance."
"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."
"In terms of probability, every now and then there are changes coming and going."
"More AI features would be good."
"Server deployment and the GUI for emails should be better."
"The product must be more customizable."
"There are security and performance issues which is one of the concerns of using an open-source product."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"There can be difficulties resolving problems on the server side when problems arise."
"We have had an issue with security."
"We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming."
"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"We pay for the license annually."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Licensing fees are paid monthly."
"Exchange is better for medium to large businesses because it can be quite costly for SMB, which may not need all the options the product provides."
"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."
"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"Its price is okay."
"The solution is competitively priced."
"The solution is not expensive compared to other products."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The price of the solution is low."
"We pay yearly licenses for Zimbra Collaboration."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
