Has improved email security through built-in encryption and supported offline work effectively
We don't use team workspace with HCL Notes; we use only Microsoft because it's incorporated with the Microsoft license. Based on my extensive experience with HCL Notes, I think HCL can make its product better by being more visible on the market because most companies don't support or use HCL anymore, and most integrators work with Exchange or Outlook rather than HCL Notes. Inside HCL Notes functionality, they have to be more visible in the market, which is very important.

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

"Security is the most valuable feature, better than you get in 365."
"It is easy to integrate the product with other services."
"The software's secure communication is particularly useful when dealing with professional entities."
"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."
"Notes is a perfectly adequate front end. It's clear and straightforward."
"The solution provides great security."
"It offers unique capabilities, excellent security, and replication features."
"It is one of the best products in the world for workflow applications."
"The web interface is powerful and easy to use."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"Zimbra Collaboration's sharing features are most valuable."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"One of the premium features was customized rooms tailored to the collaboration needs. Many of the clients customize features such as organization logos and scanners."
"The most valuable feature of Zimbra for our team's productivity is its efficiency in handling email communication."
"Good email solution and it's open-source."
 

Cons

"It is a heavy program and uses more resources than an email client should."
"Web support is very old and needs an upgrade. We can handle a different password for the client to access the mail services, compared to the web services. We need to implement many other components to get access to the web access. There could be a feature to interpret if the web access is available from any end-user equipment."
"The loading time can be excessive."
"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."
"My overall experience with HCL Notes is not good."
"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."
"I would like HCL to update Notes' development tool and make it more attractive like Microsoft Visual Studio and similar products."
"The only improvement that we're planning to do is that all our applications are still designed in the layout and format of Notes version 4, and our plan over the coming years is to modernize their look. One of the things they're developing or considering deploying is a program to automatically upgrade the look and feel of databases. If they deploy that, that will be revolutionary. In other words, we decide on a corporate look and feel for our database and press a button. We've probably got 50 different applications in Notes, and it would just go through the whole lot and upgrade all of them to look the same."
"Zimbra Collaboration's video conferencing could be improved."
"They should enhance its online meeting features."
"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 are security and performance issues which is one of the concerns of using an open-source product."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"The product must be more customizable."
"There are some bugs we found that could be fixed."
"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."
 

Pricing and Cost Advice

"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."
"The price is reasonable."
"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."
"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 not expensive compared to other products."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"We do not pay for licenses to use this solution."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the price a four"
"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."
"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."
