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

"The most valuable features of Microsoft Exchange are it is always online and has broad email and file-sharing capabilities."

"Communication is the most valuable feature of the solution."

"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."

"We've been using Exchange as an email platform; our clients require multi-country, multi-regional email collaboration with controlled mail flow, and the most valuable feature is the capability of message tracking and the protection of user data."

"It's an excellent product from Microsoft, providing more flexibility to the end-users, and as it's connected with Teams, it also enables collaboration and document sharing through emails with many user-friendly features."

"This is a good product but our version is reaching end-of-life."

"Exchange is easy to use. It also has a built-in calendar for all the stuff I'm supposed to be looking at and doing. Exchange tells you if you have a doctor's appointment or a scheduled call. It also has a place to store and manage your contacts. If I want to add a new contact, it will put in information about that contact stored anywhere within the Microsoft Suite."

"It is easy to set up."

More Microsoft Exchange pros

"We can control all the data in my IT infrastructure."

"The stability is good and keeps getting better with each new update."

"This is a good email solution and it's open-source which is great and the most important feature for us."

"The configuration is simple."

"Zimbra Collaboration is a good tool for video calls...Zimbra Collaboration's initial setup phase was easy."

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

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

"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."

More Zimbra Collaboration pros

Cons

"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."

"The support needs to be more knowledgeable."

"Deployment should become a bit easier, the process is a bit complicated. You have to have done it one or two times before you get it right. The first time you do it, it won't be perfect. There are a lot of complications compared to Gmail For Business, which is a bit easier when it comes to configuration."

"Microsoft Exchange and other Microsoft solutions like Office 365 need to provide more detailed information for customers regarding the features and functionalities included in their plans, as some features are only available at an additional cost."

"Exchange took time to be deployed. It requires extensive configuration and setting up servers and managing internal network access."

"The price of Microsoft Exchange could improve, it is priced high."

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

"I would like to see the search capability of the Outlook client improved"

More Microsoft Exchange cons

"Zimbra Collaboration's video conferencing could be improved."

"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."

"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."

"Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server. They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure."

"Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange."

"The tool should improve its multi-cloud feature."

"They should enhance its online meeting features."

"The solution could use more integration with third-party tools."

More Zimbra Collaboration cons

Pricing and Cost Advice

"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."

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

"Microsoft doesn't have a unit price, it's based on the quantity, and they offer great discounts."

"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."

"The solution's pricing is fine...I do think the tool offers value for money."

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

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

"The product is quite cheap."

More Microsoft Exchange pricing and cost advice

"The solution is competitively priced."

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

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

"Zimbra Collaboration is expensive, and there is no perpetual license option."

"We pay yearly licenses for Zimbra Collaboration."

"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."

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

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