Reliable email service has supported consistent communication and improved user training

I do use Cisco Secure Email, Grafis, and Proofpoint Email Protection when needed, but we were using Proofpoint before, and we are no longer using it. I am currently using Microsoft Exchange as our email solution. We are a client of Microsoft; there is no partnership between my company and Microsoft. My experience with Microsoft Exchange is as good as the generic email. I do not use Microsoft Exchange to synchronize emails across devices, and it is not part of my workflow. The protocols I mostly use with Microsoft Exchange for integration are SMTP. I do not use the shared calendars feature in Microsoft Exchange. Data loss prevention is something we are not really using or utilizing at the moment. My overall review rating for Microsoft Exchange is 8.

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:

"Microsoft Exchange has good performance and is user-friendly."

"With the cloud coming in, scalability is not an issue even for Microsoft."

More Microsoft Exchange pros

"For an SMB, it is a recommendable email solution."

"For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy."

"Zimbra Collaboration's sharing features are most valuable."

"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."

"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."

"The solution is easy to implement."

"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."

More Zimbra Collaboration pros

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."

"The default storage capacity is too small."

"At the end of the day, the biggest area for improvement is having better and more knowledgeable support technicians."

"The pricing could be better, and it could have an easier implementation."

"Its search functionality can be better. It is currently not really easy."

"From a security point of view, Microsoft should enhance the new features. Technical support could also be better."

"In the version we have, I would like to see better communication between the end device and the Exchange server."

"In terms of Microsoft Exchange, I think maybe what can be done is to make it more user-friendly."

More Microsoft Exchange cons

"I would like to see a Microsoft schedule function added."

"There are some security issues."

"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."

"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."

"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."

"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."

"The solution’s forums don't have much information or documentation on administration tasks."

"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."

More Zimbra Collaboration cons

Pricing and Cost Advice

"Microsoft Exchange is a very well-priced solution."

"I have Outlook 365 Professional, and Exchange comes in the bundle with other solutions, such as Word and OneDrive. I pay for the use of the bundle monthly and I can imagine if you are a company with many licenses the pricing model would be a lot different."

"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."

"Microsoft Exchange itself does not require a license, but users who will have mailboxes will require a license. It depends on the number of users to choose which license. If you exceed 2,000 mailboxes, it's preferable to get the enterprise license."

"The product pricing is reasonable if you utilize its full suite of features."

"Licensing fees are paid monthly."

"Its price is fair."

"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."

More Microsoft Exchange pricing and cost advice

"The price of the solution is low."

"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."

"Zimbra Collaboration offers a good price-to-feature ratio."

"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."

"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."
