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 solution can scale well."
"The most valuable features of Microsoft Exchange are its ease of use, and simplicity of communication, and we can track communications between teams."
"It is a very stable tool...It is a very scalable tool."
"It is a product that is simple to manage, and easy to use."
"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."
"The initial setup is quite a straightforward process. I don't think it is a very complicated solution. Plenty of things could be more complex, but the ordinary, general settings are quite simple."
"Microsoft Exchange has good performance and is user-friendly."
"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."
"Zimbra Collaboration's sharing features are most valuable."
"The stability is good and keeps getting better with each new update."
"The configuration is simple."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"We can control all the data in my IT infrastructure."
"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 product is easy to set up."
 

Cons

"I see some drawbacks and areas for improvement; the quarantining is not fantastic because it lets a lot of spam through, and when it is notified of spam, it does not particularly alter its behavior quickly."
"From a reliability perspective, they need to improve the search engine, it is not very powerful."
"They could improve on the search function, it takes too much time."
"There is a lot of spam email that comes in, so they should add functionality to help fix this problem."
"For the next release, there are some features on the cloud-based Exchange that aren't included on-prem. It would be great if these features were made available in the next release. For instance, integration between Exchange and its on-prem calendar is not available for the on-prem solution."
"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."
"Microsoft Exchange could improve by adding artificial intelligence."
"Exchange can be a little finicky, sometimes, or flakey. Last week, for example, I had gone into my calendar to check on some briefings that I had established, and then went back into my inbox, and suddenly the view had changed. I had no idea what it was that I had done, and I couldn't figure out how to get that view back. I took a productivity hit as a result of that, trying to fix it, due to the fact that it just wasn't what I wanted. It wasn't what I was used to working with. Two different tech support people had to work with me in order to get the view back to what I wanted just so I could be productive."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The solution could improve by making it easier to use."
"Zimbra Collaboration's video conferencing could be improved."
"The solution could use more integration with third-party tools."
"There are some security issues."
"The antispam and antivirus features are hard to understand on mobile devices."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
 

Pricing and Cost Advice

"The price of Microsoft Exchange is reasonable."
"Licensing fees are paid monthly."
"Microsoft Exchange is an inexpensive application."
"The solution's pricing is fine...I do think the tool offers value for money."
"The platform has a reasonable price."

"I rate Microsoft Exchange a four out of ten for pricing because it is quite cheap, and many companies use the solution."
"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."
"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."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The solution is not expensive compared to other products."
