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:

Pros

"It is a product that is simple to manage, and easy to use."

"Provides unlimited storage for our mailbox."

"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."

"The most valuable feature of Microsoft Exchange is its ease of use."

"It's a very user-friendly application. The mail server is also valuable when compared to other services like SquirrelMail."

"This solution handles all of our primary functionality including email, message delivery, message archiving and calendars."

"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."

"Exchange is a robust system that is well suited for an enterprise environment."

More Microsoft Exchange pros

"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 configuration is simple."

"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."

"Network NG Modules are valuable to us."

"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."

"The Zimbra Collaboration's most valuable feature is web access."

"The web interface is powerful and easy to use."

"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."

More Zimbra Collaboration pros

Cons

"The platform could be more user-friendly."

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

"The licensing model could be improved."

"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."

"It is overall all good, though technical support is just average."

"Microsoft Exchange could improve by being more secure. We are always looking to have more security."

"Its stability is not so great. We can't move mailboxes because of a corrupt file or random issues, which causes headaches."

"It is important to have the updated version for scalability."

More Microsoft Exchange cons

"Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes."

"It would be great if a group chat feature were created to allow for a team environment."

"There are security and performance issues which is one of the concerns of using an open-source product."

"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."

"The log files need to be improved; they need to show us more information because a lot of detail is lacking and that's not very helpful or insightful."

"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."

"Zimbra is not very stable, but it's okay."

More Zimbra Collaboration cons

Pricing and Cost Advice

"We can get Exchange in the cloud along with the Microsoft 365 license."

"Its price is okay."

"The solution is expensive to maintain because it requires frequent updates and ongoing server maintenance."

"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."

"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."

"It would be nice if it used less resources to run on-premise."

"Its price is fair."

"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."

More Microsoft Exchange pricing and cost advice

"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."

"The price of the solution is low."

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

"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."

"The solution is not expensive compared to other products."

"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"

"The solution is competitively priced."

"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
