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

"Lotus Domino is an excellent platform for making groupware applications that are natively integrated with email."
"The most valuable feature is the access that it provides to documents, which offers us an easy way to make changes."
"HCL Notes has a non-structured database and fantastic native security, which is extremely strong, providing built-in security without needing external products."
"The security and performance of the solution are good even though our platform is variable, except for the mail services."
"It offers unique capabilities, excellent security, and replication features."
"The solution is practical, good interface, and performs well."
"The most valuable feature is security. It's very easy to manage security on records, views, and tables."
"It is one of the best products in the world for workflow applications."
"Good email solution and it's open-source."
"Zimbra Collaboration's best feature is its compatibility with Microsoft's ActiveSync protocol, which allows users to use Outlook on Windows or MacOS."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The most valuable feature of Zimbra Collaboration is the cost."
"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."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"The stability is good and keeps getting better with each new update."
 

Cons

"The loading time can be excessive."
"There is a chat component but it does not work properly."
"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."
"Some people complain that they want something more modern and jazzy."
"The interface could be more user-friendly. Some additional trainings could be added as well."
"We had trouble connecting this solution to the database from Microsoft. We have done it, although it can be easier."
"I would like to see integration with other solutions."
"It would be great if a group chat feature were created to allow for a team environment."
"There are security and performance issues which is one of the concerns of using an open-source product."
"The installation is not straightforward, it can take two days for the full implementation."
"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."
"They should enhance its online meeting features."
"The support was lacking in my experience."
"Zimbra Collaboration's video conferencing could be improved."
"The antispam and antivirus features are hard to understand on mobile devices."
 

Pricing and Cost Advice

"The solution is expensive. There are many components or features which make the price very high."
"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."
"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."
"We pay annually for the use of the solution."
"We pay licensing fees on a yearly basis."
"The price is reasonable."
"It was reasonably priced, but the product itself was not worth the cost."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"The solution is not expensive compared to other products."
"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."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"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."
"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."
