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.

Cons

"Some users encounter stability issues. I connect with the support team through my local partner, which takes time."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"For new users, it might take them some time to get used to the product."
"Its stability is not so great. We can't move mailboxes because of a corrupt file or random issues, which causes headaches."
"Deployment should become a bit easier, the process is a bit complicated. There are a lot of complications compared to Gmail For Business, which is a bit easier when it comes to configuration."
"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."
"In terms of configuring the product, that's definitely an area in which they can make some improvements on."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources."
"It does have a few bugs. However, they are small and can be worked around."
"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."
"The antispam and antivirus features are hard to understand on mobile devices."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"The support was lacking in my experience."
"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."
"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."
 

Pricing and Cost Advice

"We pay for the license annually."
"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."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"Its price is okay."
"It's a little bit expensive."
"This solution is expensive."
"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."
"It is not expensive."
"We pay yearly licenses for Zimbra Collaboration."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The solution is competitively priced."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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 do not pay for licenses to use this solution."
