Challenges with efficiency and interface lead to transition while offering some useful organization features
Office 365 has advantages over HCL Notes, offering a better interface and better categorization of emails. We get different kinds of options, including mail suggestions and AI options that can help users. Meetings, calendars, everything is in one place, making it more efficient. Office 365 offers a better interface and categorization of emails, along with options such as mail suggestions and AI features. Meetings and calendars are all integrated in one place.

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 easy to integrate the product with other services."
"HCL Notes has fantastic built-in security. The email and personal communication components are excellent, but they are some applications provided by HCL that Notes previously provided when it was under IBM and Lotus. Everyone wants email, so that's just part of the product. However, more savvy users can build their own solutions for managing information, and that's the great thing about it."
"The most valuable feature is the UI."
"The security and performance of the solution are good even though our platform is variable, except for the mail services."
"Its security is absolutely stratospheric. In an application, you can lock down to field-level security. For example, I could log in and see a field in an HR database with salaries. When you log in, you see exactly the same database, but the field with the salary just isn't there. So, you can literally have field-level security on it, and you can also have secure encryption. For example, I could give you that database allowing you to see the salary, but a calculation that shows how much they get per month in another field is encrypted. So, you won't be able to see that because you don't have the encryption key. You can implement high-level security very simply."
"It offers unique capabilities, excellent security, and replication features."
"It is one of the best products in the world for workflow applications. It works very well for workflows or decisional processes where a task needs to be first approved by someone. After that, the task moves to the next or final stage where another person approves it with some notes or attached documents."
"The software's secure communication is particularly useful when dealing with professional entities."
"Good email solution and it's open-source."
"The configuration is simple."
"The most valuable feature of Zimbra Collaboration is the cost."
"The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
 

Cons

"Regarding additional functions, the front end of the databases on the home screen looks somewhat old-fashioned. It could be modernized by the development team."
"The loading time can be excessive."
"The solution could improve by adding some more features."
"It is a heavy program and uses more resources than an email client should."
"Some people complain that they want something more modern and jazzy."
"While HCL has made significant advances in the user interface and diverse platform compatibility, some improvements could be made in user-friendliness and graphical interface enhancements."
"One area for improvement would be making the interface more user-friendly."
"I would like to see integration with other solutions."
"We have had an issue with security."
"The product must be more customizable."
"They should enhance its online meeting features."
"There are some security issues."
"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 solution could use more integration with third-party tools."
"The solution could improve by making it easier to use."
"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."
 

Pricing and Cost Advice

"We pay annually for the use of the solution."
"It is far cheaper to license. It is a third of the cost of our Microsoft license for 10 times the amount of usage. Developing applications cost a fraction of anything else. There are two reasons for that. First of all, applications are very fast to build. All the security is already built into the platform, so you don't have to worry about security at all. The other thing is that because fewer people use it than, for example, Microsoft SharePoint, the salary commanded by programmers is slightly lower. So, it is not only faster; you also get cheaper programmers. So, you really win-win-win on it."
"We pay licensing fees on a yearly basis."
"The solution is expensive. There are many components or features which make the price very high."
"It was reasonably priced, but the product itself was not worth the cost."
"The price is reasonable."
"I don't remember how much we paid when we first bought the Domino license, but now, we pay only for the passport. For 30 client licenses, we pay about $1,500 per year, and we don't consider it very expensive for the quality of the product. In our case, we need 30 client licenses. So, we buy 30 client licenses independently of the server. It is very easy for us to choose and maintain this kind of license and get the passport advantage."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"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."
"The solution is not expensive compared to other products."
"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"
