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

"I find Exchange's basic mail features to be highly valuable."
"Scalability-wise, I rate the solution a ten out of ten."
"What I love about Microsoft Exchange is the good integration since 2013, particularly its integration with the calendar and other software such as Zoom, TeamViewer, AnyDesk, etc."
"It's very well integrated with OneDrive and Teams Calendar."
"Technical support is good."
"Exchange is a robust system that is well suited for an enterprise environment. It's always up, and we hardly face any technical issues. Exchange has a web interface and integrates perfectly with Microsoft Outlook. This web interface can be easily used to change the passwords from the domain controllers."
"The most beneficial aspects of Microsoft Exchange are that it is solid, dependable, and reliable."
"I like the logistics and the Microsoft protocol of reaching Outlook anywhere."
"The backup and storage management features of Zimbra Collaboration are valuable."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"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."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
"We can control all the data in my IT infrastructure."
"Good email solution and it's open-source."
"The web interface is powerful and easy to use."
"The solution is easy to implement."
 

Cons

"I would like to see Microsoft Exchange improve their documentation."
"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."
"Its search functionality can be better. It is currently not really easy. It has the capability to search your mailbox, but it has some restrictions in terms of the number of results that you can retrieve. You can only get around 250 results. If you want to do a deeper search, you need to use different functionalities of the product. The policy that we have for handling emails is that we do not delete emails at all. If I insert the text that I am searching for in the Search field, it only retrieves a limited number of emails. To search for an email from 2010, I need to use different search functions to find what I am looking for. Microsoft can also improve its licensing for its products. Microsoft's licensing is not very easy to understand. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"Microsoft Exchange could improve security. They can elevate a lot of security features."
"The solution should be easier to deploy."
"One major area for improvement is the need for repeated authentication when running a meeting."
"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."
"The platform could be more user-friendly."
"The solution could use more integration with third-party tools."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"The installation is not straightforward, it can take two days for the full implementation."
"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."
"We have had an issue with security."
"The antispam and antivirus features are hard to understand on mobile devices."
"There are some security issues."
"I would like to see a Microsoft schedule function added."
 

Pricing and Cost Advice

"The price of Microsoft Exchange could improve. In Egypt, the price keeps increasing."
"We renew the product license with Microsoft every three years. The cost is included within a bundle of services. It's an enterprise agreement with Microsoft."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"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."
"We pay for the license annually."
"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate."
