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 initial setup is quite a straightforward process; I don't think it is a very complicated solution, as plenty of things could be more complex, but the ordinary, general settings are quite simple."
"It's so much of a part of what I do every day that I don't give it a lot of thought. It just works, for the most part, until it doesn't, in which case I call tech support."
"The solution can scale well."
"Microsoft Exchange is highly stable for the end-user systems."
"The email management system is very easy to set up, configure, and use."
"The latest versions have gotten much better about balancing the load on the backend."
"It is easy to set up."
"Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The configuration is simple."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"The most valuable feature of Zimbra Collaboration is the cost."
"The web interface is powerful and easy to use."
"The product is easy to set up."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"The product is very stable."
 

Cons

"Load balancing is lacking."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"There can be occasional challenges during the product's implementation phase, making it an area where improvements are needed."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"Microsoft needs to make some modifications to meet the current needs of the environment. For example, they need to add more cell service features because people work from home during the pandemic, and certain elements should be available as a mobile service."
"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."
"The pricing could be better, and it could have an easier implementation."
"The solution's hybrid deployment process could be improved, particularly for customers who initially started in the cloud and may want to return to an on-premises setup. Microsoft could make this transition more flexible."
"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 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."
"It would be great if a group chat feature were created to allow for a team environment."
"I would like to see a Microsoft schedule function added."
"The installation is not straightforward, it can take two days for the full implementation."
"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."
"There are security and performance issues which is one of the concerns of using an open-source product."
"Zimbra Collaboration's video conferencing could be improved."
 

Pricing and Cost Advice

"Microsoft Exchange is a very well-priced solution."
"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 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."
"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."
"I rate Microsoft Exchange's pricing a six out of ten."
"The product is quite cheap."
"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's licensing structure is too complex, but its prices are affordable, though not cheap."
"Zimbra Collaboration offers a good price-to-feature ratio."
"The solution is not expensive compared to other products."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
"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."
"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 competitively priced."
