Herad Howell - PeerSpot reviewer
Secure communications that prompts responses with room for improved user interface
I primarily value HCL Notes for its security features. The software's secure communication is particularly useful when dealing with professional entities. It ensures that business is conducted smoothly, allowing me to use my organization's email confidently, as opposed to my personal Gmail, which might not prompt responses from some entities.
Harry Murdani - PeerSpot reviewer
Helps with email services and communication with internal and external contacts
Everything is useful. The only useful thing Microsoft Exchange could do is give us more of a discount on pricing because it's so expensive. Regarding the calendaring functions of Exchange, there is a problem when scheduling an event for the whole day. When you click the whole day event, the scheduling doesn't really work. For example, if I schedule a meeting with you and block your whole day, instead of just putting a time from morning to afternoon, other people can still block your time, which results in double booking. It's kind of a bug that allows people to double-book. So, the scheduling isn't working properly yet. We also faced challenges with backup services. You need to use a third-party backup solution to back up the whole Exchange server properly. You can't use the native Windows backup services. It's like they're forcing me to buy another product, which means additional costs. The backup solution and the double booking issues. If Microsoft Exchange can fix these two things, then it will be very good.

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.

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Cons

"There is a chat component but it does not work properly."
"Some people complain that they want something more modern and jazzy."
"The loading time can be excessive."
"One minor issue was that using Notes to connect to clients not running on Domino, such as Gmail or Outlook, is not particularly great."
"GUI and replication can be improved."
"I love this product. I have used it for many years, and I have been a developer for it. If anything, it can be faster in the client version. The client version is a little bit hard. It is not fast. This is the only problem I see. Otherwise, it is a very good product."
"I would like to see integration with other solutions."
"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 main problem with Microsoft products is that we're constantly required to install patches and fixes."
"Nothing is perfect, that's why I am giving Microsoft Exchange a nine."
"The pricing could be better, and it could have an easier implementation."
"I do not have any notes for improvement."
"It doesn't work very well on a virtual machine. We had to move it around. There are also issues when you try to move it between computers."
"Currently, its administration is too cumbersome. It's unwieldy. It's slow. It consumes too many resources. Configuration needs to be much more streamlined and administratively automated."
"Microsoft needs to make some modifications to meet the current needs of the environment. For example, they need to add more cell service features because people work from home during the pandemic, and certain elements should be available as a mobile service."
"The price of Microsoft Exchange could improve, it is priced high."
"The new patches are, at times, not so good, so we don't install them, causing the tool to be not so stable overall."
"They should enhance its online meeting features."
"The installation is not straightforward, it can take two days for the full implementation."
"We have had an issue with security."
"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."
"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."
"The solution’s forums don't have much information or documentation on administration tasks."
"The tool should improve its multi-cloud feature."
 

Pricing and Cost Advice

"The price is reasonable."
"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."
"It was reasonably priced, but the product itself was not worth the cost."
"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."
"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 licensing fees on a yearly basis."
"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."
"Microsoft Exchange is a very well-priced solution."
"There is an annual cost to use Microsoft Exchange, and the price could be less expensive."
"Its price is very affordable, and basically, it is the standard of the industry. We have the Exchange 365 subscription, which includes the usage of Exchange Online. I don't know the specific cost, but it is the retail price of Microsoft 365 E3 licenses. Microsoft's licensing is not very easy to understand. Microsoft changes rules every other day, which makes it difficult for us to understand the licensing not only for Exchange but also for other products. It can sometimes be really complex to understand what you need to have in order to comply with Microsoft licensing."
"It would be nice if it used less resources to run on-premise."
"It's a little bit expensive."
"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 offers a good price-to-feature ratio."
"We pay yearly licenses for Zimbra Collaboration."
"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"
"It's very expensive. When we compare the cost with Google Workspace, it's so expensive."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
