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

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

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

"Its technical implementation is quite good, it is stable and can be accessed through all kinds of devices, and it performs pretty well."

"It has a feature that allows you to retain an email and recover it as an administrator. When you activate this feature, even if a user deletes an email, the email is still in the system, and we can retrieve it as an administrator. It is a very useful function. We turn this feature on for some of the mailboxes because we need to keep all the records. I like the way emails are classified in this solution. It makes it really easy to take a look at the most important messages. This is a really good functionality. Some of the emails directly exchanged with you are marked as important and shown in one tab, and everything else is in another tab. We usually don't have any issue with Exchange. It can be integrated with different solutions."

"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."

"It is easy to use and we can allow many users because now our users are scattered, they cover a wide area, and we can use it from anywhere, which is the main benefit for us."

"The integration of Microsoft Exchange with other tools allows for seamless collaboration and increased productivity within teams."

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

More Microsoft Exchange pros

"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."

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

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

"VMware Zimbra is an enterprise-class E-mail, calendar, and collaboration solution, built for both public and private clouds."

"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."

"The product is very stable."

"I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version."

More Zimbra Collaboration pros

Cons

"Microsoft needs to make some modifications to meet the current needs of the environment. For example, they need to add more cell service features because people work from home during the pandemic, and certain elements should be available as a mobile service."

"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."

"If it was the same product, and slightly cheaper, that would be amazing."

"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."

"Load balancing is lacking."

"The solution is stable, but it could improve. It's crashing if there is a big mail database. The Zimbra solution is better in this area."

"The filtering of spam needs significant improvement, as many spam emails are not getting detected."

"Areas of Microsoft Exchange that have room for improvement could use some deeper thinking."

More Microsoft Exchange cons

"We have had an issue with security."

"Some issues cause the solution not to function correctly or to cause downtime once a month."

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

"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."

"There can be difficulties resolving problems on the server side when problems arise."

"The solution could improve by making it easier to use."

"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 installation is not straightforward, it can take two days for the full implementation."

More Zimbra Collaboration cons

Pricing and Cost Advice

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

"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."

"Microsoft's licensing structure is too complex, but its prices are affordable, though not cheap."

"I rate Microsoft Exchange's pricing a six out of ten."

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

"There are different prices depending on the customer's use cases and amount of users. The price of the solution could improve."

"It is not expensive."

"The pricing is expensive."

More Microsoft Exchange pricing and cost advice

"The price of the solution is low."

"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."

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

"We do not pay for licenses to use this solution."

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

"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 competitively priced."

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