Hesham Hussain - PeerSpot reviewer
A good solution for large enterprises, but is expensive when compared to other solutions
Regarding the decision of increasing the number of users, it depends on the organization's choice, whether to opt for CapEx or OpEx. Both options involve expenses over the years. Building an in-house Exchange solution requires investing in hardware, storage, connectivity, and administrative resources. Office 365 shifts the budget solely to OpEx as a subscription service. Scalability is another factor. Starting a new company favors Office 365 due to cost efficiency. As the organization grows, the choice depends on available resources and technical expertise. An internal Exchange setup is feasible with skilled engineers, while Office 365 suits those lacking in-house resources.

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 used feature of Microsoft Exchange is the email capability, especially since it integrates with the calendar."
"The functionality on the user side is quite good. Exchange provides an excellent platform for collaboration between users."
"It is very well integrated with other Microsoft programs, teams, and so on. They work well together."
"Support is very good."
"The product works very well."
"The most valuable feature of Microsoft Exchange is the email storage is on the cloud. We don't have to delete emails often."
"The availability group settings are better, so it has inherent scalability. In 2010, they added several sensible rules."
"Microsoft Exchange is a powerful solution. It can easily integrate with Active Directory and other business applications. It does not require any training, it is flexible and simple to use. When comparing Microsoft Exchange to other solutions, such as Lotus Note, it is more straightforward for business."
"Zimbra Collaboration has integrated a lot of their party tools and they have good documentation available."
"Network NG Modules are valuable to us."
"We can control all the data in my IT infrastructure."
"The configuration is simple."
"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."
"The most valuable feature of Zimbra Collaboration is email functionality."
"The most valuable feature of Zimbra Collaboration is the cost."
"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."
 

Cons

"The platform could be more user-friendly."
"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."
"Microsoft Exchange needs to improve how it handles and assigns policy and security."
"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."
"They could offer simultaneous features for Exchange Online and on-premises versions. Specific features such as litigation hold and audit setups should be available on-premises."
"There are limitations in terms of the number of emails that can be sent in a minute, which makes it a little difficult for the marketing folks."
"When an update wants to come, it should just come maybe once or twice rather than having us deal with constant updating."
"Sometimes the client part generates some trouble. It can be very slow, though this might be related to our company's installation and configuration rather than the product itself."
"It would be great if a group chat feature were created to allow for a team environment."
"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."
"It is good and competent, but you have to pay for video and group chat features."
"We have had an issue with security."
"It does have a few bugs."
"The solution could use more integration with third-party tools."
"The tool should improve its multi-cloud feature."
"They should enhance its online meeting features."
 

Pricing and Cost Advice

"They are flexible when it comes to pricing, unlike most of the other vendors I have dealt with."
"It would be nice if it used less resources to run on-premise."
"Since my company is on Microsoft Cloud, we pay for the licenses per user. Compared to volume licensing, I would say the present licensing cost is not expensive."
"Compared to the other options in the market, the licensing costs attached to Microsoft Exchange seem reasonable."
"The solution's pricing is fine...I do think the tool offers value for money."
"The product is quite cheap."
"Its price is okay."
"The platform has a reasonable price."
"We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis."
"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 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."

"The solution is competitively priced."
"We do not pay for licenses to use this solution."
"The price of the solution is low."
