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…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a very stable tool...It is a very scalable tool."
"We have always used Exchange, that's a strategic choice for our company, and we are confident in Microsoft because their support is always there for us."
"We've been using Exchange as an email platform; our clients require multi-country, multi-regional email collaboration with controlled mail flow, and the most valuable feature is the capability of message tracking and the protection of user data."
"The most valuable feature of Microsoft Exchange is its ease of use."
"All features are useful; they meet the purpose of an email server."
"It is very well integrated with other Microsoft programs, teams, and so on; they work well together."
"We have found it to be a stable solution, it is scalable and easy to install."
"Microsoft support is very good."
"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 is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions."
"The product is easy to set up."
"Despite sticking with Gmail for over a decade in terms of business, Zimbra have impressed me with some other aspects as well; if the time comes, I would prefer Zimbra to my current solution."
"Good email solution and it's open-source."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"The most valuable feature of Zimbra Collaboration is email functionality."
"Network NG Modules are valuable to us."
 

Cons

"It's not always the finest solution in terms of integration with products that are not from Microsoft. It integrates very well with Microsoft products but not with third-party products."
"I don't have the best impression of customer service and support. It should be faster and more clear, and more human. T"
"We would prefer to be able to manage the solution on the cloud."
"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."
"The solution should be easier to deploy."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"In the version we have, I would like to see better communication between the end device and the Exchange server."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources. Configuration needs to be much more streamlined and administratively automated."
"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."
"There are security and performance issues which is one of the concerns of using an open-source product."
"The solution could improve by making it easier to use."
"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 solution could use more integration with third-party tools."
"Zimbra is not very stable, but it's okay."
"It does have a few bugs. However, they are small and can be worked around."
"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

"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."
"We can get Exchange in the cloud along with the Microsoft 365 license."
"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."
"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"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."
"It's working very well. There is no problem, but the price is not the best."
"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."
"Zimbra Collaboration offers a good price-to-feature ratio."
"We do not pay for licenses to use this solution."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The solution is not expensive compared to other products."
"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 solution is competitively priced."
"We pay yearly licenses for Zimbra Collaboration."
