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…

Deploys quickly and has a good web interface
Zimbra Collaboration has a good web interface When it comes to administration tasks like configuring specific filters or group signatures, I have to dig into the configuration since there's nothing in the graphical or web interface. The solution’s forums don't have much information or…

Quotes from Members

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

Pros

"We have found it to be a stable solution. It is scalable and easy to install."
"This solution handles all of our primary functionality including email, message delivery, message archiving and calendars."
"It is easy to use and we can allow many users because now our users are scattered They over a wide area. We can use it from anywhere. That is the main benefit for us."
"The most valuable feature of Microsoft Exchange is its communication capabilities."
"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."
"The solution can scale up to whatever number of users one desires."
"In general, this is a good product and I am happy with it."
"With the cloud coming in, scalability is not an issue even for Microsoft."
"We can control all the data in my IT infrastructure."
"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"Zimbra Collaboration's sharing features are most valuable."
"The solution is easy to implement."
"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 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 most valuable feature of Zimbra Collaboration is email functionality."
 

Cons

"Microsoft could improve on Exchange's hybrid deployment or HCW. They need to improve on that because I was having many issues with HCW in our environment at times."
"I think it could be more scalable."
"Sometimes we don't get support quickly enough - for example, if there's some global hacker attack, we don't get served as quickly. The skills of the technical staff can also vary, and Microsoft could perhaps improve their training."
"An improvement would be to combine Exchange and Teams so that emails, calls, and chats can be integrated into one window."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources."
"The solution could be more user-friendly."
"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."
"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 would like to see a Microsoft schedule function added."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The tool should improve its multi-cloud feature."
"It would be great if a group chat feature were created to allow for a team environment."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"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."
"Zimbra Collaboration's video conferencing could be improved."
"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."
 

Pricing and Cost Advice

"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"The platform has a reasonable price."
"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"It is not expensive."
"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."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"The pricing is expensive."
"The price of the solution is low."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"The solution is not expensive compared to other products."
"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."
"Zimbra Collaboration offers a good price-to-feature ratio."
"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."
