Effective collaboration achieved with versatile features and good customer service
There are always improvements needed. My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary. I am not an IT person; I am an educator, a trainer, a user. I want to get the work done. However, I find that the Exchange Server and possibly the way our company has set up access permissions require extensive programming knowledge. It might take six to eight weeks to get a programmer's time to build something, whereas I can use something like Smartsheet that will do everything I want without needing a programmer. Smartsheet is more end-user friendly compared to a Microsoft product. Microsoft believes an expert IT person should manage everything, however, I want to manage things on my own in a simplified way. That is not easy using the Exchange Server or Microsoft Office. It is not end-user friendly for development, and a programmer is needed. Once set up, using them as an end-user is fine. I find that the automations are not robust, and the FedRAMP systems are not robust. I have a few issues with Exchange and Office, but there's nothing I can do about it.

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

"Message trace is the most valuable feature of the product."
"It has helped us because we don't have to worry about servers crashing."
"The most valuable feature is being able to assign an individual a task."
"The platform's security and compliance features are good."
"It's pretty reliable. We haven't had any issues with it."
"The solution generally works well. We can send and receive emails just fine."
"Tech support has been great, when necessary."
"The most valuable features of Microsoft Exchange Online are spam filtering, 50 GB of email storage, good integration with Outlook, and ease of management."
"Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management. Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution."
"The most valuable feature of Zimbra Collaboration is email functionality."
"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."
"Good email solution and it's open-source."
"The product is easy to set up."
"The backup and storage management features of Zimbra Collaboration are valuable."
"It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing."
"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."
 

Cons

"The solution’s technical support could be improved."
"We'd like to have the ability to recall emails on the web. I'm not sure if that is available yet."
"There is an annual enterprise subscription could improve by having more features."
"I would prefer an anti-malware functionality in at least the basic version."
"From an IT perspective, we need clearer documentation to understand the product’s configuration process."
"The stability of the solution has room for improvement."
"The ActiveSync services and the mapping services could be improved."
"The solution should have more integration with other platforms."
"Some issues cause the solution not to function correctly or to cause downtime once a month."
"File sharing permissions with Nextcloud integration need improvement."
"In the next release, Zimbra Collaboration should include a security feature to allow access for mobile device administrators."
"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."
"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."
"We have had an issue with security."
"The solution’s forums don't have much information or documentation on administration tasks."
"The solution could use more integration with third-party tools."
 

Pricing and Cost Advice

"The product is very cheap."
"The licensing price is ok, I'd rate it as four out of five."
"The pricing for Microsoft Exchange Online is quite reasonable, in my opinion. Many licensing options are available so that we can choose based on the customer's needs. For example, if a customer only requires mailbox features, we can recommend Plan One or Plan 2. We can suggest an E3 or E5 license if they need the entire Office suite. There are also premium subscriptions for enterprise customers, offering additional security features. Overall, I don't find the pricing costly because Microsoft provides many features and security capabilities, making it reliable for all customers, depending on their requirements."
"I think it's just awesome. There's no argument about how much value you get on the per user, for user expenditure. It's really great, I don't have any issues with it. I think it's excellent."
"The pricing is based on a yearly contract and a floating license option is offered."
"The pricing is a bit more expensive than other solutions."
"I am using Office 365 and Microsoft Exchange Online comes as the package. It cost approximately $13 per month."
"The price of the license depends on a lot of factors, such as the number of licenses and company specifics."
"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."
"If you choose the network edition, it is a little pricier. They have the open-source edition too which is only community supported."
"There is an annual standard licensing fee to use Zimbra Collaboration and there is no other cost."
"The price of the solution is low."
"The solution is not expensive compared to other products."
"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."
"I use Zimbra Collaboration's community version. We may move to the enterprise version since prices are affordable."
