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

"Customers can benefit from this new pricing model because it's expensive, and now with the subscription, they can budget for this."
"Exchange is very scalable, it's one of the most important things about this software."
"Exchange is easy to use. It also has a built-in calendar for all the stuff I'm supposed to be looking at and doing. Exchange tells you if you have a doctor's appointment or a scheduled call. It also has a place to store and manage your contacts. If I want to add a new contact, it will put in information about that contact stored anywhere within the Microsoft Suite."
"It is a product that is simple to manage, and easy to use."
"Microsoft Exchange has good performance and is user-friendly."
"If you don't really mind the cost then go for Microsoft."
"It is enterprise-friendly, and many organizations use it."
"Microsoft Exchange is stable."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"The most valuable feature of Zimbra Collaboration is the cost."
"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."
"The pricing of the solution is excellent; it's a newer solution with a modern interface and dashboard, the interface itself is very responsive and easy to navigate, the initial setup is very simple and straightforward, the stability is good and keeps getting better with each new update, and the solution really does scale very easily."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The backup and storage management features of Zimbra Collaboration are valuable."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."
 

Cons

"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."
"Microsoft Exchange is highly stable. However, after receiving some updates it can be unstable."
"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."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"The only thing that could be improved is the pricing."
"One thing for improvement would be to have an offline version of Exchange available for use if our connection goes down."
"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."
"I think it could be more scalable."
"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 installation is not straightforward, it can take two days for the full implementation."
"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."
"There are some bugs we found that could be fixed."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"File sharing permissions with Nextcloud integration need improvement."
 

Pricing and Cost Advice

"Its price is fair."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"Microsoft Exchange is a very well-priced solution."
"Licensing costs for Microsoft Exchange have increased, but are still fair. For some users, the cost is high considering the number of functions and features they will use."

"It is not expensive."
"The price of Microsoft Exchange is reasonable."
"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 price of the solution is low."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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."
"The solution is not expensive compared to other products."
