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

"The deployment is a plug-and-play process."
"One of the most valuable features of Microsoft Exchange is its security."
"All of Exchange's features are valuable; for example, we can configure the MAPI profile, IM profile, or mobile profile."
"Its technical implementation is quite good, it is stable and can be accessed through all kinds of devices, and it performs pretty well."
"The best features are that Exchange is very customer-friendly, its interface is self-explanatory, it doesn't hang, and it keeps evolving."
"Our customers are satisfied with the features included in Microsoft Exchange."
"The exchange functionalities are good."
"The latest versions have gotten much better about balancing the load on the backend."
"The most valuable feature of Zimbra Collaboration is the cost."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"It is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions."
"The backup and storage management features of Zimbra Collaboration are valuable."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"The product is easy to set up."
 

Cons

"Microsoft Exchange could improve by being more secure. We are always looking to have more security."
"I think that improvements should be made in creating greater abilities for Microsoft Exchange in terms of Reasearch and Development."
"The calendar integration in Exchange is not that great. The email features are okay, but it doesn't integrate well with the calendar and appointments, especially Zoom appointments. It integrates fine with Microsoft Teams, but Zoom is a challenge."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources."
"The management of .pst files and archiving need improvement."
"The solution should be easier to deploy."
"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."
"I think it could be more scalable."
"It does have a few bugs."
"We have had an issue with security."
"File sharing permissions with Nextcloud integration need improvement."
"Zimbra Collaboration's video conferencing could be improved."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"The support was lacking in my experience."
"I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many."

Pricing and Cost Advice

"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."
"We pay for the license annually."
"We are currently using enterprise licenses for the solution. They are different pricing models available. There are individual, cloud-based, and enterprise licenses all with different pricing models. The larger the number of users, the lesser the price. For small to medium companies like us, we feel it is expensive."
"This solution is expensive."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"Its price is okay."
"The product is quite cheap."
"Licensing fees are paid monthly."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We do not pay for licenses to use this solution."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"Zimbra Collaboration offers a good price-to-feature ratio."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"We pay yearly licenses for Zimbra Collaboration."
"The solution is competitively priced."
