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

"The most valuable feature is the UI."
"I prefer to work with HCL and not with Exchange because it's easy to manage, easy to set up, and easy to migrate."
"The most valuable feature is the access that it provides to documents. This offers us an easy way to make changes."
"Office 365 offers a better interface and categorization of emails, along with options such as mail suggestions and AI features."
"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."
"People criticize Notes because its appearance is outdated, and I agree, but behind that lackluster look is an extremely substantial platform for knowledge management, information sharing, monitoring, workflow, etc."
"In summary, this is a good product but there are always some areas for improvement."
"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."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
"Zimbra Collaboration has a good web interface."
"This is a good email solution and it's open-source which is great and the most important feature for us."
"The product is easy to set up."
"For an SMB, it is a recommendable email solution."
"A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra."
"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."
"It is the best open source collaboration suite that I know, because it provides high availability and more performance than the other solutions."
 

Cons

"One minor issue was that using Notes to connect to clients not running on Domino, such as Gmail or Outlook, is not particularly great."
"I would like to see integration with other solutions."
"It is a heavy program and uses more resources than an email client should."
"Notes needs a major upgrade for the UI."
"I would like HCL to update Notes' development tool and make it more attractive like Microsoft Visual Studio and similar products."
"I would like to see integration with other solutions."
"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."
"We had trouble connecting this solution to the database from Microsoft. We have done it, although it can be easier."
"There are security and performance issues which is one of the concerns of using an open-source product."
"File sharing permissions with Nextcloud integration need improvement."
"The solution could improve by making it easier to use."
"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."
"The support was lacking in my experience. However, recently the support I received was good. Perhaps they have improved."
"The installation is not straightforward, it can take two days for the full implementation."
"We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming."
"Zimbra Collaboration does not have a solution roadmap as aggressive as the new collaboration mail solutions. Additionally, they can have a better interface and integration with single sign-on."
 

Pricing and Cost Advice

"The solution is expensive. There are many components or features which make the price very high."
"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."
"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."
"It was reasonably priced, but the product itself was not worth the cost."
"The price of the solution is low."
"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."
"Zimbra Collaboration is expensive, and there is no perpetual license option."
"We pay yearly licenses for Zimbra Collaboration."
"We do not pay for licenses to use this solution."
"Zimbra Collaboration offers a good price-to-feature ratio."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
