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

"I find Exchange's basic mail features to be highly valuable."
"The deployment is a plug-and-play process."
"The latest versions have gotten much better about balancing the load on the backend."
"If you don't really mind the cost then go for Microsoft."
"The initial setup was straightforward and fast."
"I like the logistics and the Microsoft protocol of reaching Outlook anywhere."
"Exchange has helped us with encryption."
"It's user-friendly."
"For an SMB, it is a recommendable email solution."
"For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy."
"The logs, troubleshooting, and tracking we have found to be the most valuable features, and when we have any issues with lost messages these features are useful because it is very easy to track and log."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"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."
"The stability is good and keeps getting better with each new update."
"Zimbra Collaboration has a good web interface."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
 

Cons

"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"The management of .pst files and archiving need improvement."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"The security for the email technology could be improved."
"The only thing that could be improved is the pricing."
"Microsoft needs to make some modifications to meet the current needs of the environment."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."
"The product must be more customizable."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The tool should improve its multi-cloud feature."
"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."
"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."
"The log files need to be improved; they need to show us more information because a lot of detail is lacking and that's not very helpful or insightful."
"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."
 

Pricing and Cost Advice

"It is not expensive."
"It would be nice if it used less resources to run on-premise."
"The pricing is expensive."
"Its price is fair."
"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."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"The product is quite cheap."
"I have Outlook 365 Professional, and Exchange comes in the bundle with other solutions, such as Word and OneDrive. I pay for the use of the bundle monthly and I can imagine if you are a company with many licenses the pricing model would be a lot different."
"We do not pay for licenses to use this solution."
"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."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"The solution is not expensive compared to other products."
"We pay yearly licenses for Zimbra Collaboration."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
